Abstract
Poly(vinyl alcohol) films, crosslinked by doping with potassium dichro mate and heat treatment, have been investigated dielectrically as a fu nction of curing temperature and curing time. It was found that increa se of either curing time or curing temperature lowers the charge carri er mobility and hence increases the charge-storage capacity of the fil ms. This is ascribed to complex formation, which gives rise to enhance d blacking of the segmental motion.
