摘要: Composite silica particles were synthesized by a two-step (acid-base) process in an aqueous solution with mixture of organoalkoxysilane monomers. The separates the hydrolysis and condensation procedures to easily control rate. In this study, silane monomers used phenyltrimethoxysilane (PTMS), vinyltrimethoxysilane (VTMS), methyltrimethoxysilane (MTMS), tetraethyl-orthosilicate (TEOS). physical properties resultant composite investigated change molar ratio size increased increasing RaSi(OR)3/RbSi(OR)3 or RaSi(OR)3/TEOS (Ra: phenyl; Rb: vinyl, methyl).
