摘要: In this study, flexible and low-cost graphite sheets modified by atmospheric pressure plasma jet are applied to reduced-graphene-oxide/polyaniline supercapacitors. Surface treatment can make the hydrophobic surface of into a hydrophilic improve adhesion screen-printed on sheets. After fabrication supercapacitors with polyvinyl alcohol/H2SO4 gel electrolyte, pseudo-capacitance electrical double capacitance be clearly identified measurement cyclic voltammetry. The fabricated supercapacitor exhibits specific value 227.32 F/g areal 28.37 mF/cm2 potential scan rate 2 mV/s. Meanwhile, retention reach 86.9% after 1000-cycle voltammetry test. A light-emitting diode lit supercapacitors, which confirms that function well potentially used in circuit.
