Disclosed is a free-standing hybrid nanomembrane capable of energy storage. The free-standing hybrid nanomembrane includes carbon nanotube sheets and a conducting polymer coated on the carbon nanotube sheets. The carbon nanotube sheets are densified sheets formed by evaporating an alcohol from carbon nanotube aerogel sheets. The conducting polymer is coated on the carbon nanotube sheets by vapor phase polymerization. Further disclosed is a method for fabricating the free-standing hybrid nanomembrane.

Free-standing hybrid nanomembrane as energy storage electrode and the fabrication method thereof

The present invention relates to a yarn-type micro-supercapacitor fabricated by twisting a hybrid nanomembrane coated with a conducting polymer on a carbon nanotube sheet. Thus, the yarn-type micro-supercapacitor has superior performance. Particularly, since a 2-ply electrode manufactured by being twisted together with a metal wire has very high power and energy density in liquid or solid electrolyte and also has superior mechanical strength and flexibility, the yarn-type micro-supercapacitor may be variously deformed&#x2014;for example, bent, twisted, or woven&#x2014;to maintain superior electrochemical performance.
