Preparation and Characterization of Conductive Polymer/Reduced Graphite Oxide (RGO) Composite via Miniemulsion Polymerization

Abstract

Polymer/reduced graphite oxide (rGO) composite nanoparticles were prepared via miniemulsion polymerization. The rGO was modified with a reactive surfactant, 2-acrylamido-2-methyl-1-propanesulfonic acid (AMPS). The AMPS-modified rGO was emulsified in the presence of styrene (St) and Methyl meth acrylate (MMA) monomers, and the stable miniemulsion was polymerized to form poly (St-co-MMA)/rGO composite latex nanoparticles. The structure and morphology of the composite were characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD), transmission electron microscopy (TEM) and particle size distribution of prepared composite by zeta seizer (ZS). The electrical conductivity of the reduced graphene polymer composite has been measured to be approximatel 2.5 S cm^-1
