Synthesis and Characterization of Poly(Vinylidene Fluoride).
Abstract
Poly (vinylidene fluoride) (PVF2) has been widely studied due to potential applications based on its ferroelectric nature, with both piezoelectric and pyroelectric devices possible. Structural analysis of PVF2, which involves characterization of both the polymorphism and the detailed molecular structure, has been a major area of research. One major thrust under this contract has been to examine the influence of head-to-head defects on the crystallization and melting behavior of PVF2.The first project of interest was to examine lamellar thickening during the alpha crystallization. In a second study, Hoffman-Weeks plots of melting temperature versus crystallization temperature were prepared in order to determine the equilibrium melting temperature. In the third study on crystallization and melting behavior, high temperature crystallization experiments were performed in order to determine the influence of the H/H content and the molecular weight on the solid state transformation from the alpha to the gamma phase. The second major thrust of our research has been an examination of the thermal degradation of PVF2 in solution.
