In this work, SnO2 nanoparticle dispersed Cashew nut shell liquid blended polyvinyl alcohol membrane was developed through dialdehyde crosslinking of PVA and CNSR, in addition to the preamble of mercapto succinic acid into the double bonds of CNSR. The CNSR was blended in polyvinyl alcohol at 10 wt% using DMSO as solvent. The blend membranes were analysed using SEM and FTIR analysis, further, 1%, 2% and 3% SnO2 NPs loaded PVA with CNSR (10wt%) nanocomposite membranes were prepared and characterized for their ion exchange capacity, swelling ratio, water uptake, oxidative stability and proton conductivity. The hydrophilic nature of the PVA was retained even after blending with CNSR with slight reduction in water uptake ratio. The incorporation of carboxylic acid groups through the rection between CNSR and mercaptsuccinic acid was found to enhance the ion exchange capacity. The PVA/CNSR found to have superior ion exchange capacity, water uptake and oxidative stability than that of neat polvinylalcohol membrane. The examination on proton exchange capacity reveals that the obtained PVA/CNSR has higher proton conductivity with a highest value of 0.011S cm-1.
