摘要
综述了超高分子量聚乙烯(UHMWPE)、碳纳米管(CNTs)、UHMWPE/CNTs复合体系及其纤维的研究现状,以及CNTs的添加对UHMWPE/CNTs复合体系及其纤维性能的影响;添加CNTs可有效提高UHM-WPE的耐磨性、电学性能、力学性能以及UHMWPE纤维的抗蠕变性能和热稳定性能;指出CNTs对UHM-WPE改性过程中存在的主要问题是CNTs分散性差,CNTs的生产成本高,UHMWPE/CNTs的改性机理有待进一步深入,并进一步拓宽UHMWPE/CNTs复合体系及其纤维的应用领域。
The research progress in ultrahigh molecular weight polyethylene （UHMWPE）, carbon nanotubes （CNTs） and UHMWPE/CNTs composite system and fibers was reviewed. The effect of the addition of CNTs on the properties of UHMWPE/CNTs composite system and fibers was described. The addition of CNTs can efficiently improve the wear resistance, electrical properties and mechanical properties of UHMWPE and the creep resistance and thermal stability of UHMWPE fibers. It was pointed out that the dominant problem of UHMWPE modification with CNTs was the poor dispersion and high production cost of CNTs and we should further study the modification mechanism of UHMWPE/CNTs and develop the application fields of UHMWPE/CNTs composite system and fiber.
