Effect of Carbon Black Loading on Electrical Conductivity and Thermal Degradation of Poly (Vinyl Chloride)/Poly (Ethylene Oxide) Conductive Films

Abstract

In this paper, the effect of carbon black loading on the electrical conductivity and thermal degradation was studied. Conductive polymer films based on carbon black filled PVC/PEO (50/50 wt/wt %) were prepared by solution casting technique. The result shows that the electrical conductivity increased with the increase of carbon black loading. The analysis of thermal degradation of the PVC/PEO conductive blends was performed using thermogravimetric analysis (TGA). The data from TGA indicates that the addition of carbon black into the blend has improved the thermal stability of the PVC/PEO blends.
