Effect on the melting point and heat of fusion of PVDF in barium titanate (BaTiO3)/Polyvinylidene fluoride (PVDF) composites

The effect on melting point and heat of fusion of PVDF in Barium Titanate (BaTiO3)/Polyvinylidene Fluoride (PVDF) composites as a function of wt. fractions of BaTiO3 was studied by DTA. Although the melting point of PVDF was only slightly affected, its heat of fusion changed markedly with change in wt. fractions of BaTiO3. The results are explained on the basis of interactions between PVDF and BaTiO3 in the composites.
