摘　　要：碳纳米管(CNTs)作为一种新型的纳米材料,因其独特的结构而具有特殊的物化特性。本文将多壁碳纳米管用浓硫酸与浓硝酸的混合强酸改性后,与铬鞣剂以不同的比例进行超声共混,研究经碳纳米管改性后铬鞣剂的复鞣性能。结果表明:相比于铬鞣剂复鞣,改性铬鞣剂复鞣革样的抗张强度、撕裂强度、崩破强度和三氧化二铬含量均有提高。As a new kind of nanometer material, carbon nanotubes(CNTs) had special properties due to their unique structure. Multi wall carbon nanotubes, modified by mixed acid of concentrated sulfuric acid and nitric acid, were mixed with chrome tanning agent in different proportion of ultrasound, and their retanning properties were studied. The results showed that the tensile strength, tear strength, bursting strength and the content of chromium oxide of the leathers retanned by modified chrome tanning agents were improved, compared to the leather which were retanned by pure chrome tanning agent.
