Effect of Carbon Black Loading on Electrical Conductivity and Thermal Degradation of Poly (vinyl chloride)/Poly (ethylene oxide) Conductive Films

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