Commercial Organofunctional Silanes Reagents for Coupling, Surface Modification and Thin-Film Deposition. Organofunctional silanes are widely used commer- cially due to their remarkable versatility. They are hy- brid molecules combining the functionality of a reac- tive organic group and inorganic functionality into a single molecule. This unique property is used as a molecular bridge to make inorganic materials organi- cally compatible. Typically, organofunctional silanes molecules have two reactive centers. One is characterized by at least one hydrolytically stable carbon-silicon bond, which allows the introduction of non-reactive or reactive organic functionality such as alkyl, aryl, arylalkyl, per- fluoropenylalkyl, amino, epoxy, aldehyde, ethylene and anhydride. Hydrolyzable groups, mainly chloro, alkoxy and amine, characterize the other reactive center of the silicon atom. The hydrolysable compo- nent of organofunctional silanes will hydrolyze readily with water to form silanols and allow silicon to cova- lently bond to inorganic surfaces via a condensation reaction to form a siloxane bond. In addition to forming covalent siloxane bonds with inorganic substrates, the hydrophobic nature of the silicon-carbon bond provides improved resistance to hydrolysis attack at the interphase between siloxane bond and substrate. This feature makes a matrix com- posite materials more hydrolytically stable; hence, increasing service life by providing protection against corrosion and enhancing its mechanical properties. The organofunctional silanes can be tri-functional, di-functional or mono-functional. Typical molecular structure for a tri-functional silane is: R X (CH 2 ) n Si R R R can an example be for chloro, dimethylamine or methoxy X can an example be for hydrogen, perfluorphenyl, phenyl, amino, oxy or cyano In order to initiate the hydrolysis reaction of organo- functional alkoxysilanes to subsequently form covalent siloxane bonds, a catalyst is generally required; typi- cally, a mild acid or base is sufficient. The most com- mon catalysts are acetic acid and ammonia. Chlorosi- lanes and aminosilanes are autocatalytic because the hydrolyzable groups will generate in situ hydrochloric acid or amine. The choice of hydrolyzable group de- pends on the desired rate of hydrolysis and application requirements. The tri-functional silanes, e.g. trimethoxysilanes, hy- drolyze first to form a silanol group and then condense with surface hydroxyl groups to form a hydrolytically stable covalent bond and crosslink to form a multilayer (silsequioxane) coating. This multilayer forms at the inorganic interphase and can diffuse into a porous matrix to create an interpenetrating network within the inorganic substrate; this, in turn, generates a more hydrolytically stable matrixcomposite material. The di-functional silanes, e.g. dimethothoxysilanes, also hydrolyze first to form a silanol group and then condense with surface hydroxyl groups to form hydro- lytically stable covalent bonds. The di-functional si- lanes can also form polymeric siloxane materials that

Gute Chemie. Commercial Organofunctional Silanes Reagents 2 | 3 can adhere to different types of surfaces. These types of organofunctional silanes are incorporated into for- mulations to tailor the mechanical properties of the matrix composite material. The mono-functional silanes, due to their single hydro- lyzable reactive group, form a self-assembled-monolay- er (SAM) on the inorganic substrate thus creating a uniform molecular layer on the inorganic substrate’s surface. This may offer advantages because the film thickness is easily controlled; whereas it is well known that for tri- and di-functional silanes, reproducibly con- trolling the film thickness can be quite challenging. vents are highly recommended. In order to facilitate analysis and process handling, these products are also offered as a solution in a non-polar solvent. In chromatography for example, mono-functional si- lanes are generally used to make bonded phases for analytical applications because results are more repro- ducible; whereas, due to the higher hydrolytic stability, the di- and tri-functional silanes are more commonly used to make bonded phases for sample-prep-scale chromatography, solid phase extraction (SPE) and pre- parative chromatography for the purification of active pharmaceutical ingredients (API). In addition, an important aspect of treating inorganic substrates is capping of unreacted hydroxyl groups left on the inorganic surfaces. These unreacted hydroxyl groups adversely affect performance and, therefore, are capped with a trimethysilyl group. Also, capping of hydroxyl groups eliminates hydrogen bonding and leads to free flowing particles. Hydroxyl and free water scavengers like trimethylchlorosilane and hexamethyl- disilazane are efficient; however, a customized solution of trimethylchlorosilane and hexamethyldisilazane has a higher reactivity and is more effective than either of the reagents alone. And, organofunctional silanes with a hydrolyzable dimethylamino group are versatile si- lylating reagents for capping hydroxyls. Due to it is ex- treme reactivity with hydroxyl groups, dimethylami- notrimethylsilane is a highly effective hydroxyl scavenger. The by-product formed, dimethylamine, can be easily removed by applying vacuum. It must be not- ed that dimethylamino silanes are extremely hydrolyti- cally sensitive, even more reactive than chlorosilanes. They will react almost instantaneously with moisture in the air; water contained in polar solvents, adsorbed on the surfaces of glass. When handling these types of products, the use of inert gases and anhydrous sol- Due to their versatility, organofunctional silanes in combination with metal alkoxide precursors are also used to make films and particles using sol-gel technol- ogy. Discovered and first used in the mid-1800s, a renewed interest in the sol-gel process emerged when it was found out that inorganic gels could be formed and turned into inorganic glasses without the use of a high temperature melting process. Today, the sol-gel process is extensively used for the synthesis of thin films, fibers, ceramic powders, and other organic-inor- ganic hybrid materials. Along with exceptionally low processing temperatures, this technique also creates a product with high chemical homogeneity and provides the ability to control precisely the size of its inter- spersed particles. Sol-gel technology makes possible the synthesis of materials that are otherwise difficult to obtain by regu- lar means due to problems of volatilization, high melt- ing temperatures, or crystallization. It creates hybrid materials with unique properties without the need for complex machinery or processes. Typically, reactions take place at room temperature with minimal sensitiv- ity towards atmospheric conditions and allow for fine

control of the product’s chemical composition and pu- rity; resulting in excellent homogeneity of the final gel. In particular, sol-gel technology is especially preferred for the toughness of its ceramic products, capable of withstanding much higher temperatures than conven- tional powders or coatings. The sol-gel process requires the use of appropriate chemical precursors and reagents in order to promote the growth of colloidal particles within the initial mix- ture solution. The “sol” referred to in the sol-gel pro- cess is a liquid containing a stable suspension of colloidal particles and/or monomers formed after hydrolysis and condensation of the metal alkoxide precursor solution. Through gelation, the monomers within the sol eventually link up and polymerize to form larger particles. The controlled growth of these particles causes the sol to thicken into a porous, three- dimensional gel network, which then can be dried in different ways to form the final “gel”. As listed below, the process (figure 1) can be broken down into the following major steps: hydrolysis and condensation of the metal alkoxide precursors with or without the use of a catalyst, gelation of the homogeneous sol mixture, and the removal of excess solvent and unre- acted precursors in order to dry and form the final oxide structure. Chemical precursors: These are the starting materials for the sol-gel process, the most common of which are metal alkoxides due to their high reactivity with water. They consist of a positively charged metal ion and a negatively charged alcohol part. Other organic or inor- ganic precursors include acetates, lactates, pentanedi- onates, nitrates, or chlorides. These are initially mixed with water during hydrolysis to form a solution that can then undergo a condensation reaction in order to en- courage polymerization. Precursors such as organo- functional silanes and metal alkoxides play a major role in the final gel’s effectiveness by directly affecting its porosity, refractive index, hardness, and other physical characteristics. Hydrolysis and condensation: When using a silicon- based precursor, the addition of water initiates a hy- drolysis reaction and causes the mixture solution to react and form silanol groups. Then they undergo a water condensation reaction that produces siloxane bonds in the sol that promote its polymerization. As the number of siloxane bonds begins to increase, more molecules aggregate together within the sol, turning it into a continuous gel network. The structure of the resulting gel can be anywhere from discreet colloidal particles within the mixture to a continuous polymer network. It is possible to control the structure and properties of the final gel product by carefully regulat- ing pH, temperature, and reagent concentrations throughout the reactions. Catalysts: Varying effects on gelation time, porosity, bulk, and apparent density of the final gel can be ob- tained through the use of a catalyst. Although catalysts for hydrolysis and condensation reactions are not typi- cally required, some metal alkoxides, such as alkoxysi- lanes, hydrolyze much more quickly with the addition of either an acidic or basic catalyst. If no catalyst is used during hydrolysis, the reaction may not finish complete- ly by the time condensation begins. Mineral acids, am- monia, alkali metal hydroxides, and fluoride anions are the most common types of catalysts used. It is the strength and concentration of either acid or base cata- lyst that determines the speed of the reaction. Drying: Once the gel product is obtained, it undergoes a drying process where the remaining solvent liquid is removed at room temperature and atmospheric pres- sure. This stage causes a significant amount of shrink- age and densification of the gel, creating a dried

When the gel is dried under supercritical conditions, a highly porous and lighter aerogel is produced. Specific uses for these gels are derived from the different material shapes obtained when processing the final gel product. These shapes include monoliths, films, fibers, and nanoparticles. Sol-gel derived materials have a diverse set of applica- tions. The most widespread commercial use of sol-gel products is in the fabrication of specialized material coatings. They can be either protective or decorative coatings applied to glass, metal or other types of sub- strates. These coatings provide a number of functions such as protection from corrosion and abrasion, en- hancing optoelectronic properties, and increasing con- ductivity. Sol-gel technology is used in the formation of ceramic fibers and thin glass films with practical appli- cations that include thermal insulation and fiber optic sensors, respectively. Increasing varieties of materials for dental and biomedical applications are being devel- oped using the sol-gel technology.
