Tóm tắt

Effects of coupling agent on the structures and properties of nanocomposite materials based on unsaturated polyester resin and A200 silica nanoparticles were investigated. The viscosity of the resinl A200 silica mixtures increased with increasing coupling agent content because of forming core-shell structures and the mechanical properties of polymer nanocomposites generally were better than those without coupling agent and appeared a maximum in mechanical properties at 4.0 wt percent coupling agent content. IR analyze indicated that the coupling agent had reacted with unsaturated polyester resin and A200 silica nanoparticles. SEM, Fe-SEM and TG-SDC demonstrated more homogeneous dispersion of A200 silica nanoparticles in the polymer matrix and accompanied by lower glass transition temperature and melt temperature. Furthermore, it was also found that the best dispersion route involved a methanol dispersion technique.
