In this study, surface modification of nano α-alumina with Surface modifier was silane coupling agent namely vinyl tri methoxy silane (VTMS) was implement. Salinization reaction under hydrolysis, condensation condition and different concentration of silane coupling agent with spot of isoelectric point of nano alumina was performed. After surface modification, to characterizing amount of grafting on the nanoparticles, Elemental analysis (CH), Fourier transform infrared (FTIR) spectroscopy were utilized. Vinyl Ester nanocomposites were prepared using various loadings of silane modified alumina nanoparticles. To quantitative interfacial interaction between treated nano particles and vinylester resin using tests SEM for assessment dispersion and surface fracture behavior, Dynamic mechanical thermal analysis (DMTA), Degree of cure, Haze value, Abrasion resistance (Tabber), acid chemical resistance and Pull Off adhesion. Results from FTIR and Elemental analysis revealed that the organic functional groups of the silane coupling agent layers were successfully grafted on the surface of the nanoparticles. The mechanical properties results of the vinyl ester revealed that, because of good interaction between particles and vinyl ester resin, were enhanced using 3 wt% alumina nanoparticles modified with 0.48 g silane compared with other samples.
