Pure and VO2þ ions doped PVA/MAA:EA polymer blend films were prepared by a solution casting method. XRD pattern reveals an increase in amorphicity with increase in doping. The dTGA study shows an enhancement of thermal stability of the system with increase in dopant concentration. The optical absorp...
