Effects of Washing of Raw Material on Properties of Carbon Nanotube Containing Poly(Ethylene-Terephthalate) Composites

Abstract

Our interest has been focused on mechanical recycling of poly(ethylene-terephthalate) (PET) bottle waste, because recycling of plastic waste has crucial importance nowadays. The present article deals with the effects of washing of the secondary raw materials on properties of carbon nanotube (CNT) reinforced composites. In the first step advantageous washing compounds and their concentration were determined. After selecting the proper washing method extrusion moulding characteristics of PET granulates were investigated, and effects of carbon nanotubes as reinforcing additives and also application of coupling agents on the mechanical and rheological properties of composites were studied.
