文摘

Crystalline/amorphous interphase is suggested based on FTIR and XRD results. Contrastive analysis of Cole-Cole and H-N function for relaxation processes. Dynamic heterogeneity matters much to relaxation behaviors of PVDF. αc relaxation process is found related to crystal lattice trapped dipoles. αAc relaxation process is suggested due to hopping transport process.
