| Supercapacitor is awarded as one of the greatest innovations of the20th century. It provides opportunities for fabricating novel kinds of energy storage apparatus, and has made deep influences to the development of industrial technique of human kind.As the rapid progresses of new materials discoveries and related applications, researchers'interest on supercapacitors is growing every day. These new materials such as carbon nanotubes (CNT)and electro conductive polymers (ECP)are all so called super materialswhich have promising potential for commercial applications and high value for scientific research. Therefore, it causes more attention as we combine these new materials to fabricate supercapacitors. As a result, reports on this subject explode in recent years. However, research on flexible supercapacitors is still the academic frontier in this subject, few reports have been published.Under this context, we make the first try on the research of using CNT and ECP to fabricate supercapacitors in China.In order to introduce stretchability to the supercapacitor electrode, we use the poly(dimethylsiloxane), PDMS, as the substrate of the electrode. PDMS has the splendid capability of stretch. As to the choice for active materials, we choose CNT which has strong mechanical property, high conductivity and huge specific surface area. In addition, we combine ECP such as PPy and PANI with CNT to increase the capacitive performance.We have carried out a serial of electrochemical tests and morphology characterization to evaluate the electrode's capacitive and stretching capabilities. The results show that the electrode has excellent performance both on capacitive and stretching properties. The stability of the electrode is outstanding which is critical for potentially commercial applications.Conclusively, the stretchable electrode we present in this article has promising potential for commercial applications and high value for scientific researches. |
