石墨烯与纤维的高性能化

石墨烯是纤维材料的理想增强体，其在聚合物中的分散及与聚合物基体的相互作用是复合纤维制备的关键因素。从石墨烯／ 纤维复合纺丝工艺出发，介绍了国内外石墨烯纳米复合纤维的研究进展。主要包括石墨烯的性质及功能化改性工艺，石墨烯纤维以及石墨烯与聚合物复合制备复合纤维的制备方法，并讨论了石墨烯与柔性链聚合物纤维和刚性链聚合物纤维的纳米复合过程的不同。目前石墨烯／ 聚合物基复合纤维因成本高、制备工艺复杂，尚处于研究阶段，但随着工艺的不断发展，未来可在航天航空轻质复合材料、导电纤维及耐热纤维等领域发挥重要的作用。

Graphene and enhanced fibers

Graphene is an ideal reinforcing material for fibers, and the dispersion of graphene and the interfacial interaction between the graphene and the polymer matrix are the key factors for priparing the composite fibers. Herein, the paper briefly reviews the research progress of graphene-based composite fibers home and abroad, including properties and functionality of graphene, as wellas spinning proeess of graphene fiber and grapheve/polymer composite fibers, along with the fibers based on graphene/foexible chain polymers and graphene/rigid chain polymers. The graphene/polymer composite fibers are still in research due to the high cost and complicated preparatio process, and the composite system will play an important role in the fields of aviation lightweight materials, conductive fibers and heat resistant fibers with the fast development of preparation process.
