Structural and conductivity studies of polyacrylonitrile/methylcellulose blend based electrolytes embedded with lithium iodide

Two polymer electrolyte systems consisting of polyacrylonitrile (PAN)-methylcellulose (MC) blend have been prepared using solution cast technique. For undoped material, polymer blend based films have been prepared at various PAN-MC ratios. The hydrogen bonding interaction between the two polymers is...
