中文摘要：

以石蜡和经硝酸处理过的碳纳米管（CNTs）为原料，苯为溶剂，采用真空渗透法制备了石蜡填充CNTs纳米胶囊复合材料，并设计了一个简易的热界面装置，对石蜡填充CNTs材料在电子设备热管理中的应用能力进行了测试。结果表明：石蜡成功填充到CNTs管内，且在CNTs管外基本没有残留的石蜡。在传热界面未涂抹二甲基硅油时，内外两侧最高温度的温差为4．7℃，而分别涂抹二甲基硅油、未经酸处理（20％）CNTs／Z．甲基硅油、酸处理后（20％）CNTs／二甲基硅油、（20％）石蜡填充CNTs／二甲基硅油时，其内外两侧最高温度的温差分别为3．8℃，3．1℃，3．1℃，2．2℃，说明将石蜡填充CNTs作为二甲基硅油中的散热填充物具有更好的散热效果，且增加了界面间的热反应速度和热稳定性。

英文摘要：

Paraffin- filled carbon nanotube composites were successfully synthesized by a vacuum infiltration process using paraffin and treated muhiwalled carbon nanotubes （CNTs） as raw materials and benzene as regent. A simple thermal interface device was designed to test the ability of the application in electronic thermal management of carbon nanotubes filled with paraf- fin. It was found that paraffin was successfully infiltrated into the inner space of CNTs, which was proven by TEM observations. The temperature difference between outside and inside was 4.7℃ without painting simethicone on the thermal interface. When painting simethicone, CNTs/simethieone, acid treated CNTs/simethicone and paraffin confined in CNTs/simethicone on the in- terface, the temperature differences were 3.8℃ ,3. 1℃ ,3. 1℃ and 2.2℃ respectively. It indicates that the paraffin confined in CNTs material has an excellent heat transfer ability as the filler of thermal grease.
