Characterizations and electrical conductivity of (poly[vinyl chloride])/(poly[ethylene oxide]) conductive films: The effect of carbon black loading and poly(ethylene glycol) diglycidyl ether

The effect of carbon black (CB) loading filled (poly[vinyl chloride])/(poly[(ethylene oxide]) (PVC/PEO) conductive films with and without poly(ethylene glycol) diglycidyl ether (PEGDE) was studied. The PVC/PEO/CB and PVC/PEO/PEGDE/CB conductive films were prepared by a solution casting method. The results indicate that the addition of PEGDE of PVC/PEO/CB/PEGDE conductive films exhibited higher tensile properties, electrical conductivity, and thermal stability compared with PVC/PEO/CB conductive films. The scanning electron microscope micrographs of PVC/PEO/PEGDE/CB conductive films showed a rough surface and a good distribution of CB on the surface of PVC/PEO/CB conductive films. Fourier‐transform infrared spectrum showed that the interaction between the PVC/PEO films and the CB‐PEGDE phase on the surface of the conductive films does not change the functional group of the PVC/PEO/PEDGE/CB conductive films.
