英文摘要：

The research on carbon nanotubes improved composite materials has become frontiers and hotspots in recent several years in the fields of nanomaterials for its ultrahigh characteristics and performances. And the dispersity of carbon nanotubes in the matrix exerts a significant influence on its functionality. The dispersion method（mechanical agitation, ultrasonic dispersion, electrical field-induced and chemical functionalization） and the research progress of the carbon nanotubes are summarized in detail, then the existing problems of current research is pointed out, some consi- derations such as weight loss and volume-dispersion in the future research are also analyzed.
