^aMolecular weights and polydispersity indexes determined by SEC in DMF on the basis of polystyrene calibration. The number of grafted EDOT and the approximate polymerization degree of EDOT in each PEDOT chain were calculated on SEC results. ^b, the number of grafted EDOT, and the approximate polymerization degree of EDOT in each PEDOT chain were calculated on ¹H NMR results. ^c was calculated on speculative structure construction. ^dThe grafting number of PDMA-b-PMA in macromonomer precursors was calculated by the equation . ^eThe grafting number of PDMA-b-PMA in macromonomer precursors was calculated by the equation . ^fThe number of thiophene rings of macromonomer precursors was calculated on ¹H NMR results.
