Co-Continuous Phase Structure and Properties of Poly(vinylidene Fluoride)/Epoxidized Natural Rubber Blends

Abstract:

Thermoplastic elastomer based on poly (vinylidene fluoride) (PVDF) and epoxidized natural rubber (ENR) blends at 50/50 by weight with different type of ENR (i.e., ENR with 25 and 50 mol% epoxide which are called as ENR-25 and ENR-50, respectively) has been prepared by melt blending method. Difference content of epoxide groups in ENR molecules on dynamic mechanical properties, dielectric properties and morphological properties of blends were investigated. The morphology reveals the co-continuous phase structure of PVDF and ENR phases. Furthermore, ENR-50/PVDF blend showed finer grain morphology and the glass transition (T_g) of the rubber phase was shifted to lower temperature. The structure of the blends correlated well with permittivity (ε) in dielectric properties with the permittivity of PVDF/ENR-50 higher than that of PVDF/ENR-25.
