Descrição

Descrição geral

Triethoxyvinylsilane(TEVS) is a silane coupling agent and an adhesion promoter which can be used for cross-linking and for providing an insulating layer with good mechanical and thermal properties. [1][2]

Aplicação

Development of a Hermetic Barrier Using Vinyl Triethoxysilane and Sol-gel Processing

TEVS can be used in the surface modification of silica nanoparticles (SiNPs) which can be reinforced on linear-low density polyethylene (LLDP) for food packaging applications.[3] It can be encapsulated with different pigments like protoporphrin XI[4] and methylene blue[5] to artificially sensitize the tissues for photodynamic therapy.

Triethoxyvinylsilane (TEVS) was used to modify nano-silica particles[6]and poly (vinyl acetate). [7] TEVS may undergo emulsion copolymerization with styrene (St), butyl acrylate (BA), and methacrylic acid (MAA).[8] The formation of random copolymers of TEVS with styrene (St) has been reported.[9] TEVS may undergo graft polymerization with styrene and methyl methacrylate over different silicates .[10] [11]
