Microstructural and electrical properties of $CoCl2$ doped HPMC/PVP polymer blend films

Solid polymer electrolyte (SPE) based on Hydroxypropylemethylcellulose (HPMC) and Polyvinylpyrrolidone (PVP) polymer blend films complexed with different weight ratio of $CoCl2$ were prepared using solution casting method and investigated using X-ray line profile analysis. An attempt has been made to study the changes in crystal imperfection parameters in HPMC/PVP blend films with the increase in concentration of $CoCl2$⁠. Results show that decrease in micro crystalline parameter values is accompanied with increase in the amorphous content in the film which is the reason for film to have more flexibility, biodegradability and good ionic conductivity. AC conductivity measurements in these films show that the conductivity increases as the concentration of $CoCl2$ increases. These films were suitable for electro chemical applications.
