Assessment Effect of Surface Modification of Nano Alumina with Vinyl Trimethoxy Silane to Mechanical Properties of Vinyl Ester Resin
Rostam M
This paper reports Surface treatment of nano alumina with vinyl silane coupling agents was performed. Modification with silane coupling agents is commonly method by which the interfacial interaction of particles can be enhanced with resin. Surface treatment of nano alumina was implement under hydrolysis and condensation condition at different silane concentration. The surface characteristics of the unmodified and modified aluminum pigments were investigated by means of CH and FTIR analyses. The Mechanical properties of vinyl ester resin was investigated by the Dynamic mechanical thermal Analysis (DMTA). Results revealed that vinyl silane adsorbed on the surface of alumina under sol-gel reaction. Also, the mechanical properties of the vinyl ester composite was significantly enhanced with surface treated particles.
