Microstructure and properties of silane monomer-modified styrene-acrylate nanocoatings
Microstructure and properties of silane monomer-modified styrene-acrylate nanocoatings by photopolymerization were investigated using TEM, TGA, FTIR and UV-Vis measurements. The transmittances of the microemulsions and final nanolatexes as well as the acid and base resistances of the final nanolatexes decrease and acid, base and water resistances of the nanocoatings increase with increase in the monomer to surfactant mass ratio and gamma-methacryloxypropyltrimethoxysilane (KH570) content. The polymer particles are nearly spherical and are very uniform with the number average particle size of 25.5 nm and Dw/Dn of 1.11. FTIR spectrum indicates the possible structure of the organosilicone modified styrene-acrylate copolymer.
