SEBS-g-MA was dissolved in toluene at a concentration of 50 g L − 1 and a predetermined volume
fraction of PANI was added. Chemical reaction between the amine group of PANI and the maleic anhydride functional groups of SEBSgMA leads to a covalent amide bond between the middle block of the copolymer and the conducting polymer. The proof of the presence of the amide bond and the complete FTIR characterization is described in ref.
