Comparative Study on Electrical Behavior of Silicon/Fullerene/CuI Dispersed Composite Polymer Electrolytes.

This paper presents the comparative study of electrical characterization for Si/C60/CuI dispersed composite polymer electrolyte thin films. Thin polymer films are prepared for different wt% of dispersoid with the host polymer electrolyte (PEO: NaI) matrix. Si and CuI are used as procured and C60 is prepared in the laboratory and the same has been verified with NMR data sheet. Furthermore, the prepared films are subjected to structural and electrical characterization. The composite nature of the films is verified with the X‐ray diffraction and Fourier Transform Infrared. The complex impedance spectroscopy is used to analyze the electrical conductivity of the samples. The polarization technique is performed to calculate the transference of ion (T¬ion). The concentration and mobility of charge carries are calculated to explain and to support the change in conductivity. [ABSTRACT FROM AUTHOR]
