Abstract
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 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 ≈ 80% of the original capacitance value was retained.
