β-phase polyvinylidene fluoride (
PVDF)–BaTiO
3 nanocomposite samples have been prepared by solution mixing method. XRD data represent that the crystallinity of
PVDF decreases with increase in loading level of BaTiO
3 nanoparticles. DSC curve represents that the melting point of
PVDF is lightly affected by loading concentration of BaTiO
3. The morphology and microstructure of
PVDF and
PVDF embedded by BaTiO
3 nanofillers were investigated by using inverted contrast microscopy (ICM) and scanning electron microscopy (SEM).
FTIR interferrometry is proven that
PVDF and BaTiO
3 are not chemically interacting; therefore, interaction of BaTiO
3 is van der Waals type of interaction. The thermally stimulated discharge current (TSDC) of
PVDF and
PVDF–BaTiO
3 nanocomposites sample was characterized by single peak. The observed TSDC peak is discussed on the basis of dipolar and interfacial polarization.
