Abstract:	In this study, the PVDF (Poly (vinylidene fluoride))/silica hybrid composites are prepared by mixing PVDF and silica, which was synthesized by sol-gel process. We changed R (the molar ratio of water/TEOS) during the sol-gel process, and made a film. The crystallinity of PVDF in the hybrid is measured by DSC (Differential scanning calorimetry), and the morphologies are observed with SEM pictures. We found that the silica particles could be well dispersed in PVDF, and R-value influenced the particle size and the crystallinity of PVDF. The concentration of TEOS also influenced the particle size and shape of silica. Higher concentration of TEOS made the silica particles have round shape and also lowered the crystallinity of PVDF.
