Summary Membranes of Poly (vinylidenedifluoride‐co‐hexafluoropropylene) (PVDF‐co‐HFP) are prepared successfully and investigated for thermal, mechanical and electrochemical properties. A considerable influence in ionic conductivity by varying the time of sulfonation has been achieved. Membranes with higher degree of sulfonation exhibit higher proton transport at room temperature. Herein we prepared a series of PVDF‐co‐HFP membrane by varying sulfonation time (6, 8, 10, 13 & 15 hrs). Mechanical properties have been investigated by UTM (Universal Testing Machine) and thermal study has been done by TGA (Thermogravimeteric Analysis). The electro chemical properties of the membranes are found to be increase without compromising the thermal and mechanical characterises.
