Kurzbeschreibung (Abstract)
We investigated the dielectric properties of crystalline poly(vinylidene fluoride) (PVDF)/poly(methyl methacrylate) (PMMA) blends in a wide range of frequency f at various temperatures T A large peak of the dielectric loss epsilon''(f) due to the interfacial polarization was found in the blend below the frequency region of the alpha(c), process. Such a peak was not observed in neat PVDF. The difference may be ascribed to the existence of a large amount of PMMA at the crystal-amorphous interphase in the blend. We also demonstrated that a low T peak in epsilon''(T), which was thought of as an interfacial peak, is not related to the alpha(a)Li. process of PVDF in the interphase, but to the beta process of PVDF.
