What is silane treatment?
Silane treatments of surfaces involve a liquid phase or vapor phase chemical reaction , and are straightforward to perform and of low cost. A typical silane surface modification reaction is illustrated in Figure I.2.12.4 (although some details of this reaction have been questioned, see Schlecht and Maurer, 2011). Silane reactions are most often used to modify hydroxylated surfaces. Since glass, silicon, alumina, titania, and quartz surfaces, as well as other metal oxide surfaces, are rich in hydroxyl groups, silanes are particularly useful for modifying these materials. Numerous silane compounds are commercially available, permitting a broad range of chemical functionalities to be incorporated on surfaces (Table I.2.12.4). The advantages of silane reactions are their simplicity and stability, attributed to their covalent, cross-linked structure. However, the linkage between a silane and a hydroxyl group is also subject to hydrolysis, and film breakdown under some conditions must be considered (Wasserman et al., 1989 ).

Why is silane important?
Water molecules at the interface tend to replace the resin–fiber covalent bond by weaker hydrogen bonds, hence silane plays an important role in reducing water absorption in cellulosic–fiber-reinforced composites.

However, the linkage between a silane and a hydroxyl group is also subject to hydrolysis, and film breakdown under some conditions must be considered (Wasserman et al., 1989 ).
Can silanes form a film?
Silanes can form two types of surface film structures. If only surface reaction occurs (perhaps catalyzed by traces of adsorbed surface water), a structure similar to that shown in Figure I.2.12.4 can be formed.
Is silane a pyrophoric compound?
One consequence of this reversed polarity is the greater tendency of silane to form complexes with transition metals. A second consequence is that silane is pyrophoric — it undergoes spontaneous combustion in air, without the need for external ignition. However, the difficulties in explaining the available (often contradictory) combustion data are ascribed to the fact that silane itself is stable and that the natural formation of larger silanes during production, as well as the sensitivity of combustion to impurities such as moisture and to the catalytic effects of container surfaces causes its pyrophoricity. Above 420 °C, silane decomposes into silicon and hydrogen; it can therefore be used in the chemical vapor deposition of silicon.

It is a colourless, pyrophoric, toxic gas with a sharp, repulsive smell, somewhat similar to that of acetic acid. Silane is of practical interest as a precursor to elemental silicon . " Silanes " refers to many compounds with four substituents on silicon, including an organosilicon compound.
Who discovered silane?
In 1857, the German chemists Heinrich Buff and Friedrich Woehler discovered silane among the products formed by the action of hydrochloric acid on aluminum silicide, which they had previously prepared. They called the compound siliciuretted hydrogen.
How is silane made?
For classroom demonstrations, silane can be produced by heating sand with magnesium powder to produce magnesium silicide (Mg 2 Si), then pouring the mixture into hydrochloric acid. The magnesium silicide reacts with the acid to produce silane gas, which burns on contact with air and produces tiny explosions.
Is silane a precursor to silicon?
While diverse applications exist for organosilanes, silane itself has one dominant application, as a precursor to elemental silicon, particularly in the semiconductor industry. The higher silanes, such as di- and trisilane, are only of academic interest.
What is silane coating?
2.3.6 Silane coatings. Silanes are a group of silicon-based organic–inorganic materials, which are biocompatible. In aqueous solution, silanes readily hydrolyze and form silanol groups (SiOH) that enable their attachment to any hydrated metal surface (metal-OH) through the formation of silicon (Si)–oxygen–metal bonds (Plueddemann, 1991 ).
What is silane coupling agent?
Organofunctional silane coupling agents function as adhesion promoters for PICA in a manner similar to that for fiberglass and mineral-filled composites. The general conditions are similar; that is, an organic polymer is bonded to an inorganic substrate. Bond failure mechanisms in PICA adhesion systems are similar to those in other adhesion promoter applications. Moisture attack in the bonded interfacial region is a leading cause of loss of adhesion. A silane coupling agent, with its dual functionality, operates at the interface to induce improved adhesion when the bond is initially formed, and then to “protect” the bonded system from moisture-induced debonding and increase its useful life.
What solvent is used to make silane?
Various solvents can be used: methanol, ethanol, isopropanol, an ether glycol, or sometimes a mixture of solvents.
Why is silane oligomer poor adhesion?
Poor adhesion is obtained if the silane coating is too thick. A thick, cross-linked silane oligomer is a weak layer and the bond would fail in the silane layer. Poor adhesion is also obtained if the silane coating is too thin because not enough silane is present to give improved bond strength and water resistance.
What is the best concentration of silane for primer?
A concentration of 0.5–10% silane in the solvent can be used in a primer, but usually levels of 2–5% are used.
How to apply silane to PICA?
Silane adhesion promoters are applied to PICA in two possible ways – adding as a primer on the substrate before the coating is applied or directly to the coating system. When used as a primer, the silane is diluted in a solvent and sprayed, dipped, or wiped onto the inorganic substrate. Various solvents can be used: methanol, ethanol, isopropanol, an ether glycol, or sometimes a mixture of solvents. Water, at levels of 1–5%, is sometimes added to an alcohol solvent to promote hydrolysis of the silane during attachment to the surface. Water can also be used as the solvent if the coupling agent is an aminosilane, because aminosilanes are soluble in water.
What solvents are used in primers?
Various solvents can be used: methanol, ethanol, isopropanol, an ether glycol, or sometimes a mixture of solvents. Water, at levels of 1–5%, is usually added to an alcohol solvent to promote hydrolysis of the silane in the primer.

Does silane have a hydrophobic surface?
As a result, the hydrocarbon chains provided by the reaction of the silane produce a cross-linked network due to covalent bonding between fibre and polymer matrix. This results in a hydrophobic surface in the fibre, which in turn increases the compatibility with the polymer matrix. As mentioned earlier silane coupling agents have been effective ...
