Abstract

original image

Between the sheets: Polystyrene–polyacrylamide copolymer is covalently grafted onto graphene sheets by in situ living free-radical polymerization to give “amphiphilic” graphene nanoplatelets. The block copolymer disperses graphene nanoplatelets in a polar solvent (water; see picture, A versus C) and also stabilizes them in a nonpolar solvent (xylene; B versus D).
