Effect of chlorine-containing polymer additive on dielectric performance of polymer dielectric films

A polymer dielectric film with chlorine (Cl)-containing polymer additives was fabricated to investigate the effect of additives on dielectric performance. Polychlorostyrene or polyvinyl chloride (PVC) was used as a polymer additive in the polymer film. At 0.1 V and 10 Hz, the polymer dielectric film with PVC had a dielectric constant of 23.6 with a dielectric loss of 0.04. This film exhibited a 73% increase in dielectric constant compared with the film without additives. The increment in the dielectric constant was attributed to the high polarisability of Cl atoms.
