碳纳米管／炭黑／天然橡胶复合材料的性能研究

研究碳纳米管／炭黑／天然橡胶复合材料的性能。结果表明：碳纳米管的加入能明显提高复合材料的定伸应力，具有一维教向排列且长径比较大的碳纳米管Flotube 7000对物理性能的提高作用明显；碳纳米管与炭黑并用对提高复合材料的导热性能具有一定的负协同效应。;The properties of carbon nanotube/carbon black/NR composites were studied. The rsults showed that carbon nanotubes could obviously increase the modulus of the composites，and Flctube 7000 with aligned structure and high length-diameter ratioimproved the physical properties si；nificantly. However， negative synergistic effect on the thermal conductivity of the composites was found by blending carbon nanotubes with carbon black
