Extensive research has been attempted to apply for conducting polymers as the electrodes of secondary batteries, because they have several important characteristics such as longer cyclic life, less self-discharge rate, endurance to overdischarge, lower cost, more flexible shape, and easier to make thin films. Among them, polyaniline(PANI) is the most promising candidate for the electrode materials since it has a good redox reversibility and easily prepared with low production cost. However, the polymer electrodes have low volume energy density. Here, PANI/multi-walled Carbon nanotube(MWCNT) composites were prepared by ex-situ and in-situ polymerization method to improve their electrical property. And the dc conductivities of PANI/MWCNT according to content and diameter size of MWCNT were measured by four-point probe. Also the morphology of the PANI/MWCNT composite was investigated by field emission scanning electron microscope(FE-SEM) and transmission electron microscope(TEM). |
