Abstract
AbstractPoly(vinylidene fluoride) (PVDF) composites with different ratios of zinc phenylphosphonate (ZPP) were prepared by mixing in a kneader. The crystallization behavior of the composites from the melt was investigated by polarized optical microscopy (POM), differential scanning calorimetry (DSC), and wide‐angle X‐ray diffraction (WAXD). The POM observations directly showed that nucleation of the PVDF crystal was promoted by adding ZPP. The data obtained from DSC measurements also indicated that the crystallization temperature of the composites became higher than that of pure PVDF. These results suggested that ZPP acted as a good nucleating agent for PVDF. Nonisothermal crystallization behavior was analyzed by Avrami equation adopted by Jeziorny. The results of the analysis were found to be consistent with the POM observations for the composites. WAXD analysis suggested that the PVDF crystal structure was influenced by ZPP addition. These results proved that as a nucleating agent, ZPP increased the crystallization rate and temperature of PVDF. POLYM. ENG. SCI., 2013. © 2012 Society of Plastics Engineers
