摘　　要：应用导热系数测量仪,测量了中空微球填充聚丙烯复合材料的等效导热系数(keff),并对前期研究中所得到的等效导热系数公式进行了初步验证.结果表明,除个别点外,keff的理论估算值和实测值有较好的一致性.当中空微球体积分数φf≤20%时,随着φf的增加,keff大致呈线性减小.当φf较低时,keff随中空微球粒径的增加而有所下降.The effective thermal conductivity （keff） of hollow microsphere-filled polypropylene （PP） composite was measured by using a thermal conductivity instrument, and the equation of effective thermal conductivity published in the previous paper was preliminarily verified. The results show that the estimated values of keff are in good agreement with the measured ones except few points, and that keff decreases roughly linearly with the volume fraction （φf） of hollow microsphere when φf≤20%, while decreases slightly with the increase in particle diameter at lower φf.
