We report the synthesis of poly((styrene-random-(2-azidoethyl acrylate)) through free radical polymerization and azidation for the stable dispersion of graphene. The polystyrene parts anchor on to the reduced graphene oxide (rGO) as a non-covalent functionalization. On the other hand, poly(2-azidoethyl acrylate) parts help in stabilizing as the functionalized rGO (f-rGO) in organic solvents. The SBR/f-rGO composite is finally prepared by the thermal crosslinking of azide groups of the poly(2-azidoethyl acrylate) parts with the unsaturated bonds of rGO and SBR (allyl group and vinyl groups) through nitrene reactions. Thus, a new method of producing of stretchable composites with good dispersion due to the covalent interaction between graphene and SBR has been successfully developed.
