摘要：Miniaturization of supercapacitors offers an attractive route to the fabrication of portable and wearable electronic devices, but still suffers from limited areal capacity. Herein, we utilize a facile stamping approach to fabricate flexible paper-based micro-supercapacitors that are based on the ternary composite containing polyaniline (PANI) as patterned interdigital electrode materials. The ternary composites are composed of PANI, metal-organic frameworks derived from porous carbon (C800) and low-oxidized graphene (LGE). Benefiting from the synergy of C800 and LGE, the electrical conductivity and capacitance retention of PANI composites were enhanced, obviously. The resultant composites displayed high areal capacitance of 162 mF cm(-2), remarkable energy density of 24.9 mu Wh.cm(-2), 90 % capacitance over thousands of charge-discharge cycles and excellent stability against bending even at large angles.
