Abstract
The polystyrene–silica hybrid materials have been successfully prepared
from styrene and tetraethoxysilane in the presence of silane-coupling agents by an in
situ sol-gel process. Triethoxysilyl group can be incorporated into polystyrene as side
chains by the free-radical copolymerization of polystyrene with silane-coupling agents,
and simultaneously polystyrene–silica hybrid materials with covalent bonds between
two phases were formed via the sol-gel reaction. The 3-(trimethoxysilyl)-propyl-methacrylate
(MPS) systems were found to be more homogeneous than the corresponding
allytrimethoxysilane hybrid system of equal molar content. In the MPS-introduced
system, the thermal properties of the materials were greatly affected by the presence of
MPS. FTIR results indicate successful formation of the silica networks and covalent
bonding formation of coupling agents with styrene. The homogeneity of polystyrene–
silica systems was examined by scanning electron microscope and atomic force
microscope.
