Dielectric study of polymer nanocomposite films for energy storage applications

Abstract

In the present study we have a novel report on the types of dielectric studies of the two blend polymer consisting of polyacrylonitrile (PAN) as the host polymer-polyethylene oxide (PEO) as a copolymer, LiPF6 as lithium salts and clay containing different weight percent of DMMT as modified montmorillonite. The polymer nanocomposite (PNC) films were prepared by using solution cast technique. However the pure PAN-PEO+LiPF6 film was prepared as a reference. Keeping in view of characterization of PNCs films were study by impedance spectroscopy technique. The high frequency range of dielectric measurement is 1 Hz-1 MHz. This technique is shown to be a viable and straight forward means of obtaining dielectric data on polymer electrolytes. Permittivity (??), dielectric loss (??) and a.c. conductivity variation with frequency was studied to estimate the relaxation times for PAN-PEO polymer electrolyte. ?
