摘要：Currently there is a need to develop new devices capable of storing energy which should belightweight, flexible and friendly to the environment. The aim of this research was to present the synthesis andcharacterization of cassava starch conducting polymer and polypyrrole films which were used in thedevelopment of an electrochemical accumulator. The starch films were chemically synthesized from nativecassava starch adding plasticizers and lithium perchlorate. Moreover, polypyrrole films were electrochemicallysynthesized and doped with p-toluenesulfonic acid and indigo carmin. The characterization was carried outusing electrochemical techniques of cyclic voltammetry and electrochemical impedance spectroscopy. Theresults indicate excellent electrochemical behavior of cassava starch films and polypyrrole films and good redoxactivity which allow the accumulation of charge in the electrochemical accumulator device. This opens thepossibility of using these organic devices as an electrochemical charge accumulators.
