The effect of nano tio2 and nano boron nitride on mechanical, morphological and thermal properties of wf/pp composites

Abstract

This study evaluated the effect of nano boron nitride (BN) and nano titanium dioxide (TiO2 ) on some physical, mechanical and thermal properties of WF/PP composites. Polyproplene as a polymer matrix and wood fl our obtained from particleboards were used as reinforcing fi llers to prepare the composites by using a single screw extruder. It was observed that density in all composites did not change signifi cantly with the increasing of wood fl our. It was found that BMOR and BMOE of the composites increased with the increasing of the wood fl our content and nanoparticle types, while the TMOR and TMOE decreased. According to the results of thermal properties (TGA), thermal degradation of all composites was found to be lower compared with pure PP.
