摘　　要：本文在超高分子量聚乙烯(UHMWPE)凝胶纺丝过程中加入极少量的改性纳米活性炭(比表面积≥1000 m^2/g)来改善纤维的抗张强度。实验结果表明,在改性纳米活性炭比例为12.5,添加量达0.075 phr时,UHMWPE/改性纳米活性炭纤维的可延伸比数值达极大值398,抗张强度可达另一极大值7.8 Gpa。This paper aims to improve the ultradrawing and ultimate tensile properties of UHMWPE fibers by incorporating very small amounts of functionalized activated nanocarbon （FANC） fillers with specific surface areas higher than 1000 m2/g during gel spinning process of UHMWPE fibers. The experimental results show that the maximum achievable draw ratio obtained for the best prepared UHMWPE/FANC fiber reaches 398 and the ultimate tensile strength （σf） of the best prepared UHMWPE/FANC drawn fiber reaches around 7.8 GPa, when the mass fraction of FANC is 0.075 phr.
