Abstract
MWNT/DAAQ(1,5-diaminoanthraquinone) composites were prepared by chemical polymerization of DAAQ onto MWNT and their capacitance was evaluated by means of cyclic voltammetry in 1M $H_2SO_4$ electrolyte. The performances of such cells have been compared with pure MWNT and DAAQ based electrodes. The SEM image shows that DAAQ was coated onto MWNT during polymerization and thermal stability from th TG analysis. The highest specific capacitance values of 97F/g were observed with AC-MWNT/DAAQ composite electrode. And MWNT/DAAQ based composite electrode also showed relatively good electrochemical behaviors better than MWNT electrode in sulfuric acid electrolyte.
