摘　　要：近年来,随着资源枯竭和塑料污染问题越来越严重,以纤维素为代表的生物质资源得到关注。纤维素作为自然界储量最丰富的可再生资源,具有生物可降解性及较好的生物相容性。但是,其在加工时存在由强氢键网络引起的溶解和成型问题。在介绍纤维素透明薄膜发展现状的基础上,基于不同尺寸和形态的纤维素对纤维素透明薄膜进行了分类介绍,并且,展望了其研究的发展方向,主要包括再生纤维素薄膜、纤维素纳米纸、全纤维素复合薄膜及透明木材薄膜。关于再生纤维素薄膜的研究集中于绿色溶剂的开发及力学性能的优化,纤维素纳米纸实现了高强度与高透光性,全纤维素复合薄具有较好的力学性能及生物降解性,透明木材薄膜在保留其天然结构的同时,提高了透明性与强度。大量研究表明,不同类型的纤维素薄膜有较好的光学性能、力学性能及环境友好性,在包装、光电器件及柔性电子等领域具有广阔的应用前景。In recent years,the depletion of resources and the increasing concerns regarding plastic pollution have propelled cellulose-based biomass resources into the spotlight.As the most abundant renewable resource in nature,cellulose features biodegradability and good biocompatibility.However,cellulose cannot be melt-processed and its dissolution requires special solvents mainly due to the strong hydrogen bond network.Based on the introduction of the development status of transparent cellulose films,categorizes and presents an overview of transparent cellulose films made of cellulose of different sizes and forms,including regenerated cellulose films,cellulose nanopapers,all-cellulose composite films and transparent wood films.The research on regenerated cellulose films focused on the development of green solvents and the optimization of mechanical properties.Cellulose nanopapers exhibit high mechanical strength and high optical transmittance,all-cellulose composite films demonstrate excellent mechanical properties and biodegradability,while transparent wood films achieve a unique combination of transparency and strength by retaining the natural anisotropic structure.Numerous studies have demonstrated the exceptional optical properties,mechanical characteristics,and biodegradability of these diverse cellulose films,indicating their extensive potential in the applications for packaging,optoelectronic devices,and flexible electronics.
