Abstract
Relaxor-like behaviour was recently reported by Zhang et al. in P(PDF/TrFE) copolymers of (50/50) and (65/35) contents irradiated with high energy electrons in the paraelectric phase. To get more information on the nature of polymer relaxors we studied temperature dependence of complex dielectric permittivity of P(VDF/TrFE)(75/25) copolymer with Tc more distanced from the glass transition. Raman and IR spectra were used to characterize the conformational disorder.
