Three nonelectrolyte samples and one gel polymer electrolyte sample were prepared from poly(vinylidene fluoride) (PVDF), propylene glycol carbonate (PC), and LiClO 4 in the present article. Fourier transform infrared spectroscopy, dynamic mechanical analysis, differential scanning calorimetry, thermogravimetric analysis, X‐ray diffraction, and scanning electron microscopy were used to study morphology structure of all the samples. Results showed that there were great interactions among PVDF, PC, and lithium salt, which led to different morphology properties of different samples. Interactions between PVDF and PC mainly occurred on the surface area of PVDF crystalline, while interactions between PC, PVDF, and lithium salt mainly occurred in the amorphous area. © 2004 Wiley Periodicals, Inc.
