英文摘要：

Polystyrene （PS）/carbon nanotube （CNT） composites are novel polymer-based composites developed in recent years, wherein CNTs with unique 1 D nanometer structure are dramatically debundled and homogeneously dispersed in nanometer-scale in PS matrix. They usually exhibit greatly enhanced mechanical, electrical and thermal properties relative to the corresponding neat PS, and thus have potential applications in various fields. Here, the structural characteristics, preparation, purification and properties of CNTs are introduced briefly first. Then, the recent progress in the preparation, structure characterization and properties of the PS/CNT composites is reviewed in detail. The PS copolymer/CNT composites are also introduced.
