영문 초록

We have incorporated nanocarbon materials such as carbon nanotubes (CNTs) or reduced graphene oxide (rGO) on to a stretchable substrates using spray coating to produce stretchable supercapacitor. The physical properties of the nanocarbon materials were characterized by FT-IR and Raman spectroscopy. The Electrochemical properties of the stretchable supercapacitor were measured by cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS). Galvanostatic charge/discharge tests were also carried out. The impedance and charge/discharge curves of the nanocarbon based stretchable supercapacitor show good capacitive behavior even after repetitive stretching to 100% strain. The highest capacitance value obtained for the stretchable supercapacitors were 61.3 F g⁻¹ with polymer based electrolyte as a polyvinyl alcohol (PVA)/H₃PO₄. The stretchable supercapacitors retained 86% of its initial capacitance value at 100% strain.
