Electrically conductive polymer/rGO (reduced graphene oxide) films based on styrene and n-butyl acrylate are prepared by a variety of aqueous latex routes involving ambient temperature film formation. Techniques miniemulsion polymerization using GO as surfactant "physical mixing" approaches (i.e., mixing an polymer with dispersion) employed, followed heat treatment the to convert rGO. The distribution sheets electrical conductivity depend strongly preparation method, conductivities in range 9 × 10–4 3.4 102 S/m. Higher obtained physical compared polymerization, which is attributed former providing higher level self-alignment rGO into larger linear domains. present results illustrate how within these hybrid materials can some extent be controlled judicious choice thereby attractive means nanoengineering for specific potential applications.
