In recent years, there has been some significant research papers on graphene-based composites with a polymer matrix. Jang and Zhamu (2008) reviewed the processing of graphene nanoplatelets (GNPs) for fabrication of composite materials [108]. Mack et al. (2005) prepared nanocomposites of polyacrylonitrile (PAN) nanofibers strengthened by GNP, which they demonstrated to have improved mechanical qualities [109].
