摘要
本文对碳纳米管与环氧树脂(Epoxy-EP)复合材料的导热性能进行了定量的研究,探索了CNTs/EP复合材料的制备方法,运用Hotdisk热常数分析仪研究了CNTs/EP复合材料的导热系数;利用CNTs/EP两相复合材料的导热理论模型得到了室温下单壁碳纳米管(Single-Wall Carbon Nanotubes-SWCNTs)的导热系数为3980 W/(m.K),双壁碳纳米管的导热系数(Double-Wall Carbon Nanotubes-DWCNTs)为3580 W/(m.K),以及多壁碳纳米管(Multi-Wall Carbon Nanotubes-MWCNTs)的导热系数为2860 W/(m.K)。
The thermal conduction performance of carbon nanotubes / epoxy resin （CNTs/EP） composites materials were investigated quantificationally. The preparation method of CNTs/EP composites materials was obtained. Thermal conductivities of CNTs/EP composites materials were measured by hotdisk thermal constants analyser. Thermal conductivity of the two-phase composites materials could be predicted by the theoretical model. Finally, the numerical solution of the theoretical model could be obtained. The thermal conductivity of single-wall carbon nanotubes （SWCNTs）, double-wall carbon nanotubes （DWCNTs and multi-wall carbon nanotubes （MWCNTs） were 3980 W/（m·K）, 3580 W/（m·K） and 2860 W/（m·K） respectively.
