This study investigates flexible quasi-solid-state SnO2/CNT nanocomposite supercapacitors fabricated using a dc-pulse nitrogen atmospheric-pressure plasma jet (APPJ). The optimal APPJ processing time is merely 15 s. Cyclic voltammetry (potential scan rate = 2 mV/s) shows an areal capacitance of 3.86 mF/cm(2) when flat and 4.42 mF/cm(2) under bending (bending radius R = 0.55 cm), indicating good functionality under flexing. The capacitance retention rate is 98.3% as evaluated after a 1000-cycle cyclic voltammetry test under bending (R = 0.55 cm), suggesting good operational stability. (C) 2017 Elsevier Ltd.
