Novel amphiphilic perylene-polyglycidol was successfully prepared for graphene dispersion. The intercalating of polyglycidol into graphene multilayers was achieved via pi-pi interactions between perylene core and multilayer graphene structure. The hybrid composite exhibits stable dispersion properties in both water and DMF even for over 2 months. (C) 2013 Elsevier B.V. All rights reserved.
