摘　　要：近年来,为了发挥碳纳米管的真正效用,其研究方向以碳管纤维、薄膜、三维泡沫等宏观组装体为主。其中碳纳米管纤维不仅克服了单根碳管尺寸问题,更能体现碳管本身的优异性能。本文通过引入双马来酰亚胺聚合物在碳管纤维中构建交联网络结构,采用多种固化方式获得差异化碳管界面结构,实现碳管纤维热/电输运性能的调控。本文研究结果可为设计制备具有可调控能量输运特性的智能碳管纤维提供理论指导及实验评价手段。In recent years, in order to play the real role of carbon nanotubes, the main research direction of carbon tubes is carbon fiber, thin film, three-dimensional foam and other macro-assembly body, in view of the carbon nanotubes as a dispersed phase to improve the performance of matrix materials failed to play a carbon tube utility. In addition to overcoming the size of single carbon nanotubes, carbon nanotube fiber can also reflect the excellent performance of itself. In this paper,a cross linked network structure is constructed by introducing bismaleimide polymers into carbon nanotubes fibers. And we use a variety of curing methods to further obtain differentiated carbon tube interface structure, the control of the thermal/electrical transport performance of carbon fiber is realized according to these methods. The results of this study can provide theoretical guidance and experimental evaluation methods for the design and preparation of intelligent carbon nanotube fibers with controllable energy transport characteristics.
