Silanization

Silanization

Silanization is the covering of a surface through self-assembly with silane-like molecules.
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.

Properties

Silanized surfaces have the following properties:

Alkoxysilanes

The alkoxy groups usually used are the methoxy (-OCH3) and the ethoxy (-OCH2CH3) groups.

Aminosilanes

*APTES (3-aminopropyl)-triethoxysilane
*APDEMS (3-aminopropyl)-diethoxy-methylsilane
*APMES (3-aminopropyl)-dimethyl-ethoxysilane

Glycidoxysilanes

*GPMES (3-glycidoxypropyl)-dimethyl-ethoxysilane

Mercaptosilanes

*MPTS (3-mercaptopropyl)-trimethoxysilane
*MPDMS (3-mercaptopropyl)-methyl-dimethoxysilane
