Abstract

This study with aim of investigation the effect of Nano SiO2 on the physical, mechanical and morphological properties of hybrid Nano composite from polypropylene-wood flour was done. For this purpose, wood flour at 60% weight ratio with polypropylene in extrusion were mixed and Nano SiO2 with 0, 1, 3 and 5% as variable agent were used. Also 4% of MAPP in all compounds as a coupling agent was used. Then Nano composites were manufactured by using injection molding techniques. Then mechanical tests such as tensile and bending and physical tests such as water absorption and thickness swelling in short time according to the ASTM standard was done on the samples. Also To determine how to dispersion of nanoparticles in polymeric matrix was used of Scanning Electron Microscope (SEM). Results showed that increase of SiO2 Nano particles, has positive effect on the mechanical properties and caused the improve them. With Increase in the amount of SiO2 Nano particles the water absorption in Nano composites were increased, but this process for thickness swelling was decrease.
