Abstract

Nanomaterials of copper and cobalt were formed in alcohol in a novel way.  Incorporation of   these materials by simple solution casting technique in poly vinylidene fluoride-co-hexafluoropropylene (PVDF-HFP) polymer films significantly improves their electrical properties.

These films have higher dielectric permittivity and lower dissipation factor (tanδ) at room temperature, compared to the pure PVDF-HFP. The incorporation can be used to increase the dielectric constant of the pure film at 20 Hz frequency upto a maximum of four times.

Presence of α- and β-phases and spherulitic crystal structure of PVDF-HFP of these nanocomposite films have been detected by XRD, FTIR, DTA and FESEM studies.  The incorporation of the nanomaterial  in the polymer matrix  activates the transition of phase between α and β. This provides higher mobility of the charge carriers which participate in the interfacial polarization.

 These nanoparticles are easy to fabricate and environment friendly and their presence  in polymer matrix  to get enhanced  electrical properties will have a significant contribution in the present day research in electronics.
