摘　　要：利用熔融共混法制备了AlN/ABS复合材料。研究了AlN的添加量对复合材料导热性能及电性能的影响。结果表明,随AlN含量的增加,复合材料的热导率逐渐增加。而经表面处理过的AlN填充的复合材料的热导率明显提高。当AlN体积分数为15%时,复合材料的的热导率为0.56W/(m.K)。复合材料的热导率的计算模型可描述为:lnk=Φ1lnk1+Φ2lnk2+Φ3lnk3。AlN的加入几乎没有改变复合材料的电绝缘性能。Aluminium nitrate/ABS （AIN/ABS） composite was prepared by means of melt blending. The effect of AIN content on the thermal and electrical conducting properties of the composite was studied. The results showed the thermal conductivity of the composite increased gradually with the increase of ALN content, and the thermal conductivity of the composite filled with surface-treated AIN was obviously improved. The thermal conductivity of the composite was 0.56 W/ （m·K） when the volume fraction of AIN was 15%. The calculating model for the thermal conductivity of the composite could be described as ln k=Φ1ln k1＋Φ2ln k2＋Φ3 lnk3. The addition of AIN did not change the volume and surface resistivity of the composite.
