Effect of silver nanoparticles on the DC conductivity in chitosan-silver triflate polymer electrolyte

A solid polymer electrolyte composed of chitosan and silver triflate (AgCF(3)SO(3)) has been prepared by the solution cast technique. The formation of polymer-salt complex has been confirmed by X-ray diffraction. The DC electrical conductivity of chitosan-silver triflate electrolyte has been investi...
