Electrospun membranes of polyacrylonitrile are prepared, and the electrospinning parameters are optimized to get fibrous membranes with uniform bead-free morphology. The polymer solution of 16wt.% in N,N-dimethylformamide at an applied voltage of 20kV results in the nanofibrous membrane with average fiber diameter of 350nm and narrow fiber diameter distribution. Gel polymer electrolytes are prepared...
