The rapid development of society presents an increasing demand for polymer materials. It is impossible for new polymers prepared only by synthesis method to satisfy the ever-growing requirement. Polymer-d composite materials with high performance, multi-functionalization and intelligence show tremendous potential. Research on graphene modified polymer represents one of the most advanced technology developments, and the modified polymer exhibits great application prospect in enhancing the mechanical strength and thermal/electrical conductivity. It becomes the important way to promote the national competitiveness in graphene and polymer industry.
