Capacitive behavior of latex/single-wall carbon nanotube stretchable electrodes
In this report single-wall carbon nanotubes (SWNTs) were coated onto latex using spray coating to produce a stretchable electrode. The electrochemical properties of the electrode were determined using cyclic voltammetry and electrochemical impedance spectroscopy and galvanostatic charge/discharge tests were also carried out. The impedance and charge/discharge curves of the latex/SWNTs electrode showed good capacitive behavior even after repetitive stretching to 100% strain. The highest capacitance value obtained for the unstretched SWNTs electrode was 119 F g(-1) in 1 M Na2SO4 at 5 mV s(-1). After the 100th stretch approximate to 80% of the original capacitance value was retained. (C) 2014 Elsevier Ltd. All rights reserved.
