Fig. S6 Cyclic voltammetry of the GO-rr-P3HT
The GO-rr-P3HT films were coated on the ITO conductive glass. Platinum was used as the counter
electrode,
saturated
calomel
electrode
as
a
reference
electrode,
and
tetrabutylammoniumhexafluorophosphate (Bu4NPF6) in acetonitrile as the supporting electrolyte
（scanning range was from -3V to 3V, scanning rate was at 50 mV/s）.
TG analysis was used to quantify the proportion of rr-P3HT coupled to the GO. For convenient
comparison, the similar grafting efficiency is controlled. TG analysis of GO-rr-P3HT of different Mn
showed that the proportion of rr- P3HT coupled to the GO is ~55%. The TG thermograms of GOrr-P3HT are presented in Fig S7.
