(a) Transmission (T at λ = 550 nm) versus sheet resistance (Rs) measurements for ITO/PET (black rectangle) compared to the properties of a PEDOT-SWNTs film on a PET substrate (blue rectangle), PEDOT-SWNTs + (0.1 M) HClO4 (red rectangle). The solid line represents a fit to the experimental values obtained for the films on PET. Insert shows optical images of PEDOT-SWNTs + (0.1 M) HClO4 on a PET substrate. (b) Transmittance curves vs wavelength for the three different films (ITO, PEDOT-SWNTs and PEDOT-SWNTs + (0.1 M) HClO4); (c) Normalized sheet resistance of ITO/PET, PEDOT-SWNTs/PET, and PEDOT-SWNTs + (0.1 M) HClO4/PET at various bending cycles. Bending tests were performed at a curvature radius of 2 mm. All bending tests were performed at a bending frequency of 1 Hz under inner bending conditions with a thin layer of PEDOT-SWNTs. Insert shows digital photographs for a PEDOT-SWNTs + (0.1M) HClO4/PET electrode in the flat state and with a bending radius of 2 mm.
