Abstract
Composite polymer electrolyte membranes PVdF-HFP/PVA were prepared by phase inversion technique. The prepared membranes were soaked in DI water and 6 M sulfuric acid in order to attain the porosity and functionality. The extended porosity was determined by scanning electron microscopy (SEM). Amorphous phase was enhanced by the inclusion of acid. Amorphous state provides a free path which causes the movement of ions leading to an increase in the conductivity. The infra-red spectroscopic measurements revealed the presence of acid moieties in the composite membranes and confirmed its functionality. Thermal gravimetric analysis showed high thermal stability of the membrane. The polymer membrane prepared with extended porosity [PVdF-HFP (7 wt.%)/PVA (4.6 wt.%)] exhibited maximum protonic conductivity due to the effect of high porous nature and the entrapment of acid moieties.
