摘　　要：以不同比表面积的酸蚀纳米活性炭作为成核剂加入到超高分子量聚乙烯中,通过凝胶纺丝制备高性能纤维,并进行延伸性能和抗张性能研究。结果表明,比表面积为1400 m^2/g的纳米活性炭经酸蚀后,添加量为0.0875 phr时,制备的初丝延伸纤维最大比强力可达到6.28 GPa,是未添加任何纳米成核剂超高分子量聚乙烯的2.28倍。The acid treated activated nanocarbons with various specific surface areas are added into UHMWPE as a nucleation agents during the gel-spinning proceedings of UHMWPE composite fibers. The ultradrawing and tensile properties of the nanocomposite fibers were systematic studied in this paper. The results show that the maximum value of tensile properties reached 6.28 GPa when the optimal addition contents of acid treated activated carbons with 1400 m2/g specific surface areas at 0.0875 phr. This maximum value of tensile properties is 2.28 times of that of the plain UHMWPE fiber.
