摘　　要：研究了碳纳米管(CNTs)与炭黑(CB)对聚烯烃弹性体(POE)增强效果的影响。结果表明:CB用量为40 phr时,POE基体的增强效果较好。固定CB用量为40 phr,随着CNTs用量的增加,复合材料的拉伸强度先增大后减小,撕裂强度减小,100%定伸应力、硬度增大,回弹降低,表面电阻率降低,导热系数增大;当m(CNTs)∶m(CB)为4∶40时,体系分散性较好,复合材料力学性能优异。The effects of carbon nanotubes(CNTs)and carbon black(CB)on the reinforcing property of polyolefin elastomer(POE)were investigated.The results show that the reinforcing effect of POE is good when the amount of CB is40phr.The tensile strength of the composites goes up and down with the increase of CNTs when the amount of CB is controlled in40phr,meanwhile,the tear strength,rebound and surface resistivity of the material decreases,the thermal conductivity,modulus at100%(elongation)and hardness boost.The system performs excellently in dispersion and mechanical properties when the mass ratio of CNTs/CB is4∶40.
