Study the effect of cobalt chloride (CoCl2) on the structural, optical, and electrical properties of polymer electrolyte (PVA-CoCl2) films

Abstract

A study of non-ionic polymer Polyvinyl Alcohol (PVA) in pure and transition metal salt Cobalt Chloride (CoCl2) incorporated films with different weight percentages to change the optical, electrical, structural, and chemical structure also to make electrically conductive. To prepare the material in terms of film desired weight percentage of polymer PVA alone and for doped polymer different weight percentages of transition metal salts are dissolved in deionized water at a certain temperature and a solution cast technique is followed to get the desired thickness of film. Obtained films were transparent and achieved micro-thickness film. Experimentally confirmed for betterment in optical property to enhance in terms of absorbance, transmittance, direct and indirect energy band gap, extinction coefficient, reflectance property, refractive index, number of carbon clusters, and dielectric constant. The prepared film thickness is measured by using a Mittometer. Surface morphology studies are achieved by SEM analysis in terms of top view and sectional view also thickness of the sample is confirmed. Surface roughness and Maximum Height of the Profile are confirmed by profilometry studies. Electrical property is measured to find the desired range of IV value and to understand the sample behaviour as a resistor.
