Polarization profiles in P(VDF-TFE) copolymer studied by PPS and LIMM methods

Summary form only given. In this paper we report how the PPS and LIMM methods were applied to study distribution of polarization in RT poled 95/5 P(VDF-TFE) films of 20 /spl mu/m thickness. The samples were poled either in a corona triode, or by direct application of high poling field. Our results confirm that polarization is non-uniformly distributed if moderate poling field of about 60 MV/m is applied independently on the method of poling.
