Abstract

Multi-walled carbon nanotubes (MWNTs) were oxidized by single step acid functionalization. Various weight percentages (0wt% - 2wt%) of functionalized MWNTs (fMWNTs) were blended with polypropylene (PP) to fabricate fMWNT/PP composites. The pre UV and post UV irradiation composite samples were used to study the effects of UV exposure on the composite samples. The samples were then examined by using mechanical and thermal property tests. The morphology of fracture surfaces of composite samples were investigated by Scanning Electron Microscope (SEM). It was found that 1.5wt% of fMWNTs would have optimum reinforcement performance both for pre-UV and post-UV irradiation at low fMWNTs content. It was also found that even low content of fMWNTs would have significant positive reinforcement effect to PP after UV irradiation.
