In this study, influence of surface modification of nanosilica on the mechanical properties of
unsaturated polyester based nanocomposite was investigated. Silica nanoparticles were
modified by propylene glycol and maleic anhydride. FTIR spectroscopy confirmed the
presence of the coupling molecule on the surface of modified SiO2 nanoparticles. Unsaturated
polyester/SiO2 nanocomposites were prepared by in situ polymerization method and
mechanical properties of both modified and unmodified nanocomposite samples were
compared and discussed. The results showed that surface modification of SiO2 nanoparticles
improves mechanical properties of samples, and the amount of SiO2 nanoparticles has
influence on the mechanical properties of unsaturated polester/SiO2 nanocomposites.
