摘　　要：超高分子质量聚乙烯(UHMWPE)以其优越的耐磨性能、耐低温性能、抗冲击性能、生理惰性和无毒性等性能而广泛应用于医学、交通运输、化工、体育器械、造纸、纺织、采矿等领域。但在使用过程中,UHMWPE的线性结构使得UHMWPE导热系数非常低,热量常造成UHMWPE发生分子结构蠕变和强度疲劳。因此非常有必要提高UHMWPE材料的导热性能,改善材料耐蠕变性能,提高UHMWPE的使用寿命。从填料改性法和本体拉伸结晶取向改性法对UHMPWE的导热性能进行综述,为UHMWPE的研究提供一些借鉴。Ultra high molecular weight polyethylene(UHMWPE) with superior wear resistance, low temperature resistance, impact resistance, physiological inertness and non-toxicity is used in the medicine, transportation, chemical, sports equipment, papermaking, textile, mining and other fields. But in the using process, the linear structure of UHMWPE makes the thermal conductivity of UHMWPE very low. Therefore, it is necessary to improve the thermal conductivity, creep resistance and service life of UHMWPE. The thermal conductivity of UHMWPE is reviewed from the methods of filler modification and bulk tensile crystallization orientation modification. It is hoped to provide some suggestions for the research of UHMWPE.
