The developed membranes were extensively characterized by studying their physicochemical properties (water uptake, swelling ratio, and conductivity), thermal and electrochemical properties using differential scanning calorimetry (DSC), dynamic mechanical analysis (DMA), thermo-gravimetric analysis (TGA) and lectrochemical impedance spectroscopy (EIS).

The DSC study shows the presence of a single Tg in the membranes indicating compatibility of the two polymers in flexible and transparent films.

The membranes show good stability and ion conductivity suitable for separator applications.
