Non-Isothermal Crystallization of Poly(Vinylidenefluoride)/Hollow Glass Microspheres Composites

Abstract

The Poly(vinylidene fluoride)/Hollow glass microspheres(PVDF/HGMs) composites were prepared by the method of solution blending. The non-isothermal crystallization of the PVDF and its composites were investigated with a differential scanning calorimeter (DSC). The results showed that the crystallization peaks shifted to a lower temperature and became wider with an increasing cooling rate. The HGMs caused to increase in crystallization temperature and initial crystallization temperature. In addition, the Jeziorny and the Mo methods were used to analyze the non-isothermal crystallization kinetics. The results showed that the crystallization rate rose with the cooling rate rising, however, the HGMs decreased the crystallization rates of the PVDF.
