In this stady we use bulk polymerization to produce nanocomposites of vinly ester / nano silica. The synthesis of nanocomposites materials include vinyl ester, and nano silica (include non-modify and modify). To investigate the improvement on the static mechanical and physical properties, dynamic mechanical analyzer (DMA), heat properties of vinly ester / nano silica nanocomposites. The static mechanical properties include tensile strength and modulus, impact strength and hardness. In the heat properties include thermogravimetric analyzer (TGA) and different scanning calorimeter (DSC).
Different functional groups were grafted on the titanium oxide by Fourier transform infrared spectrometer (FTIR). The crystal structure of vinly ester / nano silica nanocomposites was determined at XRD and has no significant peak as that of pure vinly ester. It is observed that the modification influenced bound force between vinyl ester and nano silica by SEM, and discove modified nano silica best than non-modified nano silica of associativity. In the mechanical properties, the results had been down for tensile strength and impact strength because the Material has been Stiffening and Changes crisp. The non-modified nano silica was better than modified nano silica in the vinly ester / nano silica nanocomposites. The glass transition (tan δ peak) had been up, when vinyl ester filled of nano silica. In the heat properties, concentration of nano silica was refledted in amarked increase of heat-resistant.
