Due to the unique properties of CNTs its own scientists called a "super fiber" has an attractive prospect in the high-tech fields. In recent years, the research center of gravity of the CNTs composites have been transferred to the polymer / CNTs composite materials, and has made great progress. CNTs and polymer composite, CNTs from nanometer to the actual operation of an effective and efficient use of the unique properties of CNTs can be achieved with the advantage of raw materials to complement or strengthen. Polymer composite materials have broad application prospects in information materials, biomedical materials, high-performance structural materials, multifunctional materials.
