摘要

A Graphene, a two-dimensional lattice of sp2-bonded carbon atoms, is one of the most exciting materials for intense research since 2004. The unique electronic properties of graphene sheets with a high specific surface area are promising for potential applications in the fabrication of various electronic devices, such as field-effect transistors, ultrasensitive sensors, and transparent electrodes, as well as novel nanocomposite materials. A great deal of effort has been made to prepare graphene nanosheets as thin as possible and homogeneously disperse them in the polymer matrix in order to obtain graphene-polymer nanocomposites with excellent mechanical and conducting properties. A good and facile approach is the molecular level dispersion of graphene into the polymer matrix via an environmentally benign modification process, even though the concentration of graphene oxide is low in the system. Among the various methods that are available for the preparation of nanocomposites, Torkelson et al employed a solid-state shear pulverization pathway that enhances the chemical and thermal properties of the product polymer-graphene nanocomposites. This method effectively synthesizes well-dispersed nanocomposites with major improvements in the mechanical properties at very low weight percentages for the polymer dispersion. Graphene-based polymer nanocomposites are very promising candidates for new high-performance materials, and therefore, graphene has attracted more attention as a potential reinforcement material in polymer matrixes. In this work, polyimide/GO nanocomposites were prepared and characterized.
