Electroplating of MnO2 nanoparticles and conductive polymer polypyrrole thin layer
Figure S1. Schematic of three-electrode electroplating system
Electrochemical properties by normalized areal measurement
Figure S2. Areal capacitance of all textile electrodes In order to express electrochemical properties with normalized electrode area, cyclic voltammetry and charge-discharge test were performed. Fig. 1S show the results of electrochemical property normalized by the area of the electrode. The areal energy capacitance showed a positive correlation with the mass of active materials normalized energy capacitance. The highest areal energy capacitance was measured to be 38.3mF/cm2 of the polypyrrole, MnO2 coated CNT-cotton electrode (PMCCT), MnO2 coated CNT-cotton electrode (MCCT), and CNT-cotton electrode (MCCT) were measured to 38.3mF/cm2, 29.7mF/cm2 and 12.1mF/cm2, respectively.
