Abstract

A nanocomposite film based on Dawson-type polyoxometalate cluster (P2W18) carbon nanotubes (CNTs) and chitosan (CS) were prepared on quartz and ITO substrates by layer-by-layer (LbL) method. These lms were characterized by UV–vis spectroscopy, cyclic voltammetry (CV) and Scanning electron micrographs (SEM). It was shown that the multilayer film are uniform and stable. The multilayer film displays high supercapacitor performances by incorporation of CNTs into the P2W18 film. The combined activity of P2W18 and CNTs components in the composite film can store and release charge for electrochemical supercapacitors, leading to excellent specific capacitance value of 0.38 mF cm-2.
