| Abstract: | Polymer composite films of two types have been prepared by dissolving (i) MgSO4 and (ii) Li2SO4 in polyvinyl alcohol (PVA) matrix. Electrical conductivity exhibits enhancement with salt addition. Preliminary studies suggest that salt ions contribute to electrical transport. In case of PVA:[MgSO4], upto 10 wt % of salt could be dissolved in the polymer matrix. Whereas, in case of PVA:[Li2SO4] free standing composite films can be formed at least with ∼ 20 wt % of salt. Composite films have been found to be partially crystalline in nature and may be useful for Li+/Mg+ ion battery applications |
