[Display omitted] •Unique SI-ATRP modification of graphene oxide particles with poly(glycidyl methacrylate) chains.•Finely tuned electrical conductivity due to the surface reduction in the single step reaction.•Hybrid 2D particles with tunable surface properties due to presence of reactive glycidyl group.•Enhanced and tunable electro-responsive performance. Unique grafting of the poly(glycidyl methacrylate) from the surface of graphene oxide (GO) with the controllable reduction of GO particles was performed in a single-step reaction using atom transfer radical polymerization technique. The control of the GO surface reduction and modification can be achieved by appropriate selection of the ratio between tertiary amine and GO particle contents. Finely tuned electrical conductivity of the GO-PGMA particles enables simple tailoring of electro-responsive properties of their silicone oil suspensions.
