摘　　要：通过添加表面活性剂和两步法的加工工艺,研究了未进行任何预处理的多壁碳纳米管对聚丙烯力学性能、阻燃性能和电性能的影响。结果显示,聚丙烯/多壁碳纳米管复合材料在具有一定抗静电能力的同时,其缺口冲击强度可达47.3 k J/m2,相对于纯的聚丙烯提高了414%。在聚丙烯溴系阻燃体系中,多壁碳纳米管比超导炭黑更适合作为导电填料,在燃烧时能抑制火焰和滴落物的产生,并能有效缩短续焰时间t1和t2,最终使复合材料具备抗静电性能,且达到V-0阻燃级别。The effects of multi-walled carbon nanotubes（ MWCNTs） without any pretreatment on the mechanical property,conductivity and flammability of PP / MWCNTs were studied through adding surfactant and two-step process.The results show that the notch impact strength of PP / MWCNTs antistatic composite is 47. 3 k J / m^2 and 414% higher than pure PP. Within the system of bromine flame retardants in PP,MWCNTs is superior to superconducting carbon black. The kind of flame-retarded and antistatic composite with MWCNTs don＇t produce flame and drops when burned,and its afterflame time is shorter,finally the composite can get V-0 rating.
