Beschreibung

Allgemeine Beschreibung

3-(Triethoxysilyl)propionitrile (TESPN) is an organosilyl sol gel that can be used as a silane based coupling agent to improve the adhesion between metal-polymeric composite. It is non-toxic and cost efficient which makes it a suitable alternative to the existing chromate treatment of metals. It can be used in surface modification of silica based surfaces.[1][2][3]

Anwendung

3-(Triethoxysilyl)propionitrile (TESPN) may be coated on quartz and aluminum by the sol-gel process.[4]

TESPN can functionalize silica nanoparticles for the fabrication of solid state electrolyte based dye sensitized solar cells (DSSCs) and for the development of PVDf based ultrafiltration membranes for antifouling applications.[5][6] It can also be used in the synthesis of SBA-15 for the formation of mesoporous silica for drug delivery applications.[7]
