Abstract
Functionalized carbon nanotubes (MWNT–COOH) was selected as conducting wrapping agent to prepare composites of MWNT–COOH and carbonized polyaniline (C–PANI), to improve the supercapacitive performance of C–PANI. The morphology was characterized by scanning electron microscope and transmission electron microscope which showed that C–PANI was trapped in the conductive network of MWNT–COOH. The electrochemical measurement results indicated the increased specific capacitance and enhanced cycling stability of C–PANI with the addition of MWNT–COOH. When the weight ratio of C–PANI and MWNT–COOH was 4:1, the specific capacitance of the composites was 149 Fg−1, and the capacitance retention was 93.7% after 1000 charge–discharge cycling.
