摘　　要：采用硅烷偶联剂对氧化锌晶须(ZnOw)进行了表面改性,并制备了氰酸酯树脂/氧化锌晶须复合材料。研究了ZnOw含量对复合材料的导热性能、电绝缘性能的影响,并运用扫描电子显微镜对材料的断面形貌进行了观察。结果表明,少量ZnOw的加入能有效改善复合材料的导热性能,且复合材料仍具有电绝缘和较低介电常数特性。其中,当晶须的体积分数达到11.7%时,复合材料的导热系数为0.79W·m-1·K-1,为纯树脂材料的2.7倍。Zinc oxide whisker was modified by silane coupling agent,and a series of cyanate ester resin composites containing the modified whisker were prepared. The effect of volume fraction of ZnO whisker on the thermal conductivity, electrical insulation properties of the composites was investigated. The morphology of fracture surfaces of the composites was also examined by scanning electron microscopy （SEM）. Results showed that addition of a little of ZnO whisker can im prove thermal conductivity of the composites effectively, while the composites still retain the relatively electrical insulation and low dielectric constant. When the volume fraction of ZnO whisker was 11.7%, the thermal conductivity of the compos- ites increased to 0. 79 W/（m . K） ,which was 2. 7 times of that of oure resin
