碳纤维作为一种特殊纤维，除了具有高比强度、高比模量、耐热、耐化学腐蚀、耐摩擦、导电、导热、抗辐射、良好的阻尼、减震、降噪等一系列综合性能外，还具有柔软性和可编织性，使得它广泛应用于航空航天、国防军事等高尖领域。但是普通碳纤维由于其结构中仍存在大量缺陷使其力学性能与理论预测值相差甚远。而作为具有优异光、电、磁、热、机械和化学性能的碳纳米管，由于其特殊的石墨化结构，在增强原丝以及碳纤维力学性能方面有着很好的应用。通过能够制备高性能纤维的凝胶纺丝法将碳纳米管/聚丙烯腈纺丝原液纺丝，将碳纳米管的增强作用和凝胶纺丝法相结合，期望能够寻找一条新的制备取向度高，力学性能强，结构缺陷少的聚丙烯腈原丝的途径。为...As a special fiber, Carbon fiber in addition to its high strength, high modulus, heat resistance, chemical corrosion, abrasion, electrical conductivity, thermal conductivity, anti-radiation, sound damping, shock absorption, noise reduction properties, also has the flexibility and weaving. That making it widely used in the fields of aerospace, national defense and military. However, the huge amount...学位：理学硕士院系专业：材料学院材料科学与工程系_高分子化学与物理学号：2072006115206
