碳纳米管在聚合物复合材料中的分散及应用

Dispersion and application of carbon nanotubes in polymer composites

综述了碳纳米管在聚合物中的常用分散方法,并介绍了碳纳米管分散表征方法以及聚合物复合材料的合成工艺。加入碳纳米管可以不同程度地改善聚合物基体的性能,但对碳纳米管在聚合物中定向分散以及其结合机理研究甚少。最后介绍了聚合物/碳纳米管复合材料应用领域。随着碳纳米管的合成、化学修饰、分散工艺的不断改善,碳纳米管的应用将逐步向用量小、产生效益高的领域发展。

This paper reviewed conventional methods for dispersing carbon nanotubes in polymers with emphasis on techniques for characterizing dispersion of the carbon nanotubes and introduced synthetic processes of the polymer composites. The fact that adding carbon nanotubes can improve properties of polymer matrices to a certain degrees is already well-known, but the studies on directional dispersion of the carbon nanotubes in polymers and the combination mechanism between them are seldom published in the related literatures. The application fields of polymer/carbon nanotubes composites were introduced. As the carbon nanotubes＇ synthesis, chemical modification and dispersion techniques improves ceaselessly, their application will shift gradually towards the fields in which the composites is produced with low dosage of the carbon nanotubes for high economic profit.
