Description

General description

n-Propyltriethoxysilane (PTES) is a mesoporous hyperbranched organosilane that can be used as a grafting agent. It can be used in the functionalization of a variety of substrates by attaching the silane groups with the surface atoms.

Application

n-Propyltriethoxysilane was used for surface modification of titania particles and nanotubes. Propyltriethoxysilane may be used as an organosilicon precursor to prepare O₂ sensor platform. They were also used to coat mesoporous silica tablets by the sol-gel technique.
