ABSTRACT

Free-standing hybridized electrode consisting of double-walled carbon nanotubes (DWNTs) and activated carbon have been fabricated for fexible supercapacitor applications. The xanthan-gum, used in our methodology, showed high ability in dispersing the strongly bundled DWNTs, and was then efectively converted to activated carbon with large surface area via chemical activation. The homogeneously dispersed DWNTs within xanthan-gum derived activated carbon acted as both electrical path and mechanical support of electrode material. The hybridized flm from highly dispersed DWNTs and activated carbon was mechanically strong, has high electrical conductivity, and exhibited high specifc capacitance of 141.5 F/g at the current density of 100 mV/s. Our hybridized flm is highly promising as electrode material for fexible supercapacitors in wearable device.
