In this project, three classes of polymer nanocomposites were developed and their processing-structure-property relationships were systematically studied. Polymethylmethacrylate (PMMA)/expanded graphite (EG) and PMMA/untreated graphite (UG) composites were prepared by direct solution blending of PMMA with EG and UG fillers. A four-point resistivity probe system was used to measure the electrical conductivity of the composites. With the increase of filler content, the electrical conductivity of the composites showed the transition from an insulator to a semiconductor.
