摘要:

相比于傳統的紡絲技術，液晶紡絲技術使用具有各向異性和高取向的液晶作為紡絲原液，能夠制備出力學性能更加優異的纖維，同時也使得石墨烯和碳納米管等先進材料纖維的制備成為可能。在此基礎上進行有機材料和無機材料的結合，能夠設計和制備應用于諸多領域的有機�矡o機雜化功能纖維，柔性超級電容器就是十分具有潛力的應用領域之一。首先介紹了液晶紡絲技術的相關基礎知識，闡述了基于液晶紡絲技術制備有機高分子纖維、無機纖維以及有機�矡o機雜化纖維的研究進展，并且介紹了有機�矡o機雜化纖維在柔性超級電容器中作為電極材料的應用進展，最后對液晶紡絲和柔性儲能器件目前存在的問題和未來的發展趨勢進行了分析和展望。

Abstract:

Macroscopic fibers with superior mechanical performance can be prepared by spinning process using anisotropic and highly oriented liquid crystal spinning dope instead of traditional one. This makes it possible to prepare fibers made from novel materials like graphene, carbon nanotube, and so on. Functional organic�瞚norganic hybrid fibers have been designed and synthesized for application in various areas on the basis of hybridization of organic materials and inorganic materials. Organic�瞚norganic hybrid fibers have great potential in assembling flexible supercapacitors. In this paper, basic knowledge of liquid crystal spinning technology was introduced firstly. Secondly, recent advances in the synthesis of macroscopic fibers assembled from organic and inorganic liquid crystals, particularly organic�瞚norganic hybrid fibers spun from liquid crystals, were demonstrated. Thirdly, recent researches of flexible supercapacitors fabricated with aforementioned hybrid fibers as fibrous electrodes were summarized. Finally, problems and future developments in the fields of liquid crystal spinning and fibrous flexible supercapacitors were discussed.
