PANI/MnFe2O4 were prepared as thin films by electropolymerizing aniline monomers onto ITO glass slides pre- spin-coated with MnFe2O4 nanoparticles. A coloration efficiency of 92.31 cm2 C-1 was obtained for PANI/MnFe2O4 film, higher than pristine PANI film, 80.13 cm2 C-1, suggesting a synergistic effect between the MnFe2O4 particles and PANI matrix. An enhanced areal capacitance as 4.46 mF cm-2 was also achieved in PANI/MnFe2O4 film compared with that of 3.95 mF cm-2 in PANI film from CV. The enhanced capacitance of the composite films are attributed to the pseudocapacitive property of MnFe2O4 and the rougher morphology caused by the embedment of MnFe2O4 particles into the PANI matrix. H2SO4 concentration and temperature effects on the supercapative behavior of the two films were studied, suggesting positive effects of decreasing H2SO4 concentration and increasing temperature during a low temperature range, relative higher temperatures can destroy the PANI structure and cause the degradation of PANI.
