Non-covalent functionalization of graphene oxide by pyrene-block copolymers for enhancing physical properties of poly(methyl methacrylate)

Abstract

Pyrene-functionalized poly(methyl methacrylate)-<italic>block</italic>-polydimethylsiloxane (Py-PMMA-<italic>b</italic>-PDMS) copolymers were synthesized <italic>via</italic> ARGET ATRP method and further used to functionalize GO through the π–π interaction between pyrene and the carbon sheets.
