Two series of 3–12 multiarm star polymers and 4-miktoarm star copolymer of butadiene and styrene, in which the Mn of arm was higher than 20 kg mol−1, were synthesized with high efficiency (from 85.0% to 96.1%) via click chemistry.
A highly efficient and clean method for the production of reduced graphene oxide via UV irradiation of aqueous dispersions of graphene oxide (GO) containing small quantities of acetone and isopropanol is developed.
