碳纳米管／环氧树脂复合材料的研究

Study on carbon nanotube/epoxy composite

研究了碳纳米管（CNTs）／环氧树脂复合材料的分散性能及电性能。探讨了碳纳米管的含量、管径和稀释剂的用量对环氧树脂电学性能的影响，并用透射电子显微镜（TEM）和扫描电子显微镜（SEM）对其进行表征。结果表明，碳纳米管的分散和含量对环氧树脂的电性能影响很大，而加入碳纳米管能够使环氧树脂由绝缘体变为导体（电阻率〈^10mΩ·cm）。

Dispersibility and electrical conductivity of carbon nanotube/epoxy composite are studied. Transmission electron microscope and Scanning electron microscope are employed to characterize the obtained CNTs/EP composite.The research results showed that the effects of carbon nanotube amount and dispersion on electrical performance of the carbon nanotube-reinforced composite are great epoxy can be made conductivity with the content of CNTs in composites.
