Effect of TCP Doping on the Remnant Polarization in Uniaxially Oriented Poly(vinylidene Fluoride) Films.

摘要

Uniaxially stretched films of poly (vinylidene fluoride) were doped (1 wt. %)with plasticizer, tricrecyl phosphate (TCP). This slight doping with TCP was found to enhance the amount of remnant polarization in the region of low poling fields and high poling fields. The pyroelectric coefficient has shown that the doping enhances a quite stable (up to about 140 C) remnant polarization after high field poling.
