Abstract

This research was conducted to evaluate the effect of chemical treatment of wood flour on physical, mechanical and morphological properties of polypropylene-nano SiO2 HYBRID NANOCOMPOSITE. For this purpose, wood flour was treated with sodium hydroxide and benzyl chloride and to ensure the chemical treatment, Fourier transform infrared (FTIR) spectroscopy tests was done on the treated and untreated wood flour. Wood flour (40%) with 60% weight ratio with polypropylene and 4% maleic anhydrate grafted polypropylene coupling agent was compounded in extrusion mixture. Also NANO SIO2 at 0, 1, 3 and 5% as filler was used. The specimens were manufactured using injection molding technique. Then mechanical tests such as bending resistance and modulus and physical tests such as water absorption and thickness swelling were measured according to the ASTM standard. Also morphological features of the Nano composites were determined using Scanning Electron Microscopy (SEM). Results showed that the bending resistance and modulus increased with by chemical treatment but water absorption and thickness swelling were decreased. With increasing the NANO SIO2 to 3% the mechanical properties increased but adding further amount reduced the mechanical properties. With increase of SiO2 Nano particles to 5% the water absorption of Nano composites were increased, but thickness swelling was decreased. The results of SEM showed an improvement in interface between filler and matrix by chemical treatment Adding 3% can be considered suitable.
