Raman spectra of GO and rGO-PEDOT:PTS hybrid films and position change in the C = C stretching band. (I) Raman spectra of GO and rGO-PEDOT:PTS hybrid films blended at a ratio of (a) 0.00:1, (b) 0.005:1, (c) 0.010:1, (d) 0.025:1, (e) 0.050:1, and (f) 0.100:1. (II, III) The position change in the characteristic strong C = C stretching band (1,436 cm-1) of the PEDOT:PTS molecule with rGO addition; the PEDOT:PTS peak at 1,436 cm-1 is blueshifted to 1,430 cm-1 when 0.05% (w/w) rGO is added. The peak position was small shifted toward longer wavenumbers at the higher rGO content of 0.10% (w/w).
