Manganese dioxide is synthesized by reduction reaction of potassium permanganate with hydrogen peroxide. The as-synthesized α-MnO2 is characterized by powder X-ray diffraction and infrared spectroscopy. The MnO2 particles are used to prepare composite films containing polybithophene (PBTh) on indium tin oxide (ITO) glass substrates. The composite films ITO/PBTh–MnO2 are obtained by electro-polymerization...
