[Display omitted] • Free-standing composite papers of SFCP@PANI were prepared. • The free-standing SFCP@PANI-2 paper was directly utilized as supercapacitive electrodes. • The SFCP@PANI-2 demonstrated an enhanced electrochemcial capacitive performance. Free-standing composite papers of SFCP@PANI were prepared by in situ polymerization of aniline on the surface of sisal fiber carbon paper (SFCP). The SFCP@PANI papers can be directly built into electrodes without the need for any binders or conductive agents. SFCP@PANI-2 exhibits excellent electrochemical performance in the three-electrode system and the coin-type symmetric supercapacitor (SSC), which indicates that it may be a promising electrode material for supercapacitor.

[Display omitted] • It is easier and cheaper to produce sisal fiber carbon paper supercapacitor electrodes in various shapes. • The free-standing SFCPs were directly utilized as supercapacitive electrodes. • SFCP-900 exhibited relatively good electrochemical properties in supercapacitor. Sisal Fiber Carbon Papers (SFCPs) with high specific surface area was obtained using a simple hydrothermal, pressing and carbonization method. The effects of calcination temperature on morphology, structure, pore structure and electrochemical properties of SFCPs were systematically studied. The free-standing SFCPs were directly utilized as supercapacitive electrodes, and the results revealed that the SFCPs calcinated at 900 °C (SFCP-900) exhibit a better specific capacity than SFCP-800 and SFCP-1000. These results suggested that the SFCP-900 has potential applications in supercapacitors. [ABSTRACT FROM AUTHOR]
