Study of thermal and some other physical properties of PVA: CuSo4 Polymer Compound

In this study, casting method has been used to create films by mixing hydrated copper sulfate CuSO4.5H2O with three different concentrations 0.5,1 and1.5 wt% with a combination of PVA/PVP in a 1:1 ratio. The three different samples of different concentration of 0.5, 1 and 1.5 have been denoted as case a, b and c respectively. In order to evaluate and confirm the crystalline quality of the final mixture, PPCu(PVA/PVP/CuSO4.5H2O), the required physical measurements were carried out, including x-ray investigations. Also, an FT-IR analysis was used to investigate the structure and chemical composition of the mixture for the three cases. The film's morphology was studied by use of SEM equipment, which showed that the PPCu mixture's particle distribution was uneven. The thermal conductivity of the mixture at different temperatures was measured using the hot disk technique. The results showed significant influence of CuSO4.5H2O concentration on thermal conductivity
