摘要: Abstract A solid polymer electrolyte composed of chitosan and silver triflate (AgCF3SO3) has been prepared by the solution cast technique. The formation polymer–salt complex confirmed X-ray diffraction. DC electrical conductivity chitosan–silver investigated between 303 423 K, using electrochemical impedance spectroscopy over frequency range from 50 Hz to 1000 kHz. was found increase with in AgCF3SO3 concentration at room temperature. obeys Arrhenius relationship up a particular temperature decreases higher temperatures due decrease ions as result nanoparticles. presence an additional semicircular arc Cole–Cole plot obtained above 328 K indicates existence grain boundaries, which can be attributed particles. particles also have proven XRD after heating 333, 363, 393 K where (1 1 1) peak Ag is observed were shown nanosize transmission electron microscopy (TEM).
