Abstract
A method for enhancing an interaction between graphene nanoparticles and a poly(styrene-co-methylmethacrylate), including modifying graphene with nitric acid to form graphene nanoparticles surface modified with one or more oxygen functionalities, melt blending the poly(styrene-co-methylmethacrylate) and the modified graphene nanoparticles to obtain a nanocomposite, and exposing the nanocomposite to microwave irradiation to form defects in the graphene nanoparticles. A blend composition, including graphene nanoparticles and a poly(styrene-co-methylmethacrylate), where the graphene nanoparticles are dispersed in the poly(styrene-co-methylmethacrylate), and the graphene nanoparticles are surface modified with oxygen functionalities.
Claims6
A graphene/polystyrene nanocomposite composition, comprising:
