The Uses of Trimethoxyphenylsilane

Phenyltrimethoxysilane is used for nanoelectronics and material science research. It is used as crosslinking agent for silicone resin and to produce polymer organic silicon compound.

The Uses of Trimethoxyphenylsilane

An organosilicate compound for nanoelectronics and material science research.

The Uses of Trimethoxyphenylsilane

TMPS can also be used in the preparation of polytrimethoxyphenylsilane (PTMS) that facilitates the removal of graphene after chemical vapor deposition (CVD). Molecularly imprinted sol gels can be synthesized by using TMPS for the fabrication of localized surface plasmon resonance (LSPR).

What are the applications of Application

Trimethoxyphenylsilane is an organosilicate compound for nanoelectronics and material science research

General Description

Trimethoxyphenylsilane (TMPS) is an organotrialkoxysilane that is used as a functional monomer in the sol-gel processing.

Flammability and Explosibility

Flammable

Purification Methods

Fractionate it through an efficient column but note that it forms an azeotrope with MeOH which is a likely impurity. [Kantor J Am Chem Soc 75 2712 1953 Beilstein 16 IV 1556.]

Advantages

The polymer molecule generated from phenyltrimethoxysilane contains a rigid hydrophobic group benzene ring and a water-permeable and breathable silica chain. It has surface activity and weather resistance and can be used as an additive in the coating industry, phenyl silica. Introducing chain links can significantly improve thermoelasticity, mechanical properties, and resin adhesion. Therefore, phenyl silicone resin is widely used as high-temperature-resistant electrical insulating paint, high-temperature-resistant coatings, and molding packaging materials.
