摘　　要：天然纤维素具有生物可降解、生物相容性好以及来源广泛等优点,但高结晶度的紧密结构导致其功能单一、可操作性差、难以实现广泛的大规模应用。将纤维素溶解重构后获得的再生纤维素能够在再生过程中将分子链进行重新排列,赋予了再生纤维素可调控空间,以获得具有特定性质与功能的纤维素材料。本文综述了纤维素溶解与再生的生产原理和策略,从材料的选择与制备方法的角度详细介绍了其具有导电功能的方案,最后进一步综述了再生纤维素在柔性电子领域的多元化应用。本文为再生纤维素进一步的技术简化与发展及其在多领域的拓展应用提供理论基础与支撑。Natural cellulose has the advantages of biodegradability,good biocompatibility,and a wide range of sources,but its compact structure with high crystallinity leads to its single function,poor operability,and difficulty in achieving a wide range of large-scale applications.The regenerated cellulose obtained after the dissolution and reconstruction of cellulose can rearrange the molecular chain during the regeneration process,giving the regenerated cellulose a controllable space to obtain cellulose materials with specific properties and functions.In this review,the production principle and strategy of cellulose dissolution and regeneration were first reviewed,followed by a discussion of fabrication approaches for conductive cellulose from the perspective of material selection and preparation methods.Finally,the diversified applications of regenerated cellulose in the field of flexible electronics were described.This review provided a theoretical basis and support for further technological simplification and development of regenerated cellulose,as well as its expansion and application across various fields.
