摘要
自然界中的蛋白质材料具有天然丰度、多种化学成分、可调控的性能、优异的生物相容及可降解性能等特点,为柔性光电子器件的发展提供了新的机遇.然而,蛋白质化学稳定性差、机械柔性不可控等缺点使得传统加工技术难以应用在其表面,严重制约了其在柔性电子领域的应用.本文首先以丝蛋白和角蛋白为例介绍了天然蛋白材料的介观重构以及加工技术,阐述了天然蛋白质材料的多级网络结构与其物理性能的关系.在此基础上,侧重介绍它们在柔性传感、发光、晶体管及存储等器件中的应用,最后展望了蛋白基柔性材料在光电子器件发展中所面临的挑战以及发展机遇.
Protein materials in nature are abundant and have various chemical components,controllable properties,and excellent biocompatibility and degradability,which are useful characteristics for the development of flexible optoelectronic devices.However,due to the poor chemical stability and uncontrollable mechanical flexibility of proteins,the application of traditional processing technologies to the protein materials is difficult,which seriously restricts their use in the development of flexible electronic devices.This review firstly introduces the mesoscopic reconstruction and processing technologies of natural protein materials by taking silk protein and keratin as examples,and shows the relationship between the multi-level network structures of these materials and their physical properties.Then,the application of these materials in flexible sensors,light emitting devices,transistors,and memory devices is introduced.Finally,the challenges and opportunities of protein-based flexible materials in the development of optoelectronic devices are discussed.
