What is "silanization"

n. (context chemistry English)The covering of a surface which contains hydroxyl groups (metal oxides, glass, etc) with a coating that contains silane-like molecules. Thus making the surface chemically inert.

Silanization is the covering of a surface through self-assembly with organofunctional alkoxysilane molecules. Mineral components like Mica, glass and metal oxide surfaces can all be silanized, because they contain hydroxyl groups which attack and displace the alkoxy groups on the silane thus forming a covalent -Si-O-Si- bond. The goal of silanization is to form bonds across the interface between mineral components and organic components present in paints, adhesives, etc. Silanization (or siliconization) of glassware increases its hydrophobicity and is used in cell culturing to reduce adherence of cells to flask walls.
