Thermal, electrical, and sensing properties of composite material from environmental and industrial wastage

Abstract

This work is an endeavour to contemplate a valueadded conductive plastic composite material derived as recycled plastic depending on Polyethylene (PP)/carbon black. We choose to add Carbon black (CB) as a filler material in order to enhance the electrical conductivity as well as other properties associated with the composite. Solution mixing method was adopted to develop this composite where the consequences of CB loadings on various parameters like processability, morphology and thermal stability of the composites were examined. Electrical conductivity increased with the increasing amount of the CB loading. The clearly perceived better filler-matrix interaction and filler dispersion were observed in images obtained from Scanning Electron Microscope (SEM). These are the underlying reason behind the improved electrical, thermal, sensing and dielectric properties of the prepared plastic composite material.
