| 摘 要： | 近年来由于不可再生资源的日益枯竭,以及全球能源危机等问题,生物质资源的研究和利用受到人们的广泛关注。以往材料的制备与合成往往以石油及其衍生物为原料,过程繁琐、成本高昂、原料不可再生,且对生态环境造成了不可逆转的破坏,而生物质基材料因绿色、可再生、环境友好等,其设计与构筑已成为基础科技研究的前沿与热点。在过去的研究中,国内外学者以相关生物质为基础构筑“基石”,利用其本征结构及特性原位合成或与异质单元复合,构筑了大量的功能光学材料。功能光学材料的应用领域包括但不限于催化、光动能转换、生物成像、光电器件、海水淡化、信息防伪等。笔者对生物质基光学功能性材料方面的代表性成果进行梳理与总结,主要包括林木芳香生物质荧光材料、多糖生物质荧光材料、林木生物质光热材料、纳米纤维素光子晶体材料、生物质基光热材料,以及以上材料在食品检测、生物成像、加密打印、发光器件、光 热 动能转换领域中的应用,并且对该领域内存在的问题及未来发展方向作了展望。

| Abstract: | In the past,the preparation and synthesis of materials often take petroleum and its derivatives as raw materials,which are tedious,costly,nonrenewable and cause irreversible damage to the ecological environment.To conquer these problems,the design and construction of biomass-based materials have become the frontier and hot spot of both the basic science and technic research because of their sustainability and environment-friendly properties.In recent years,more and more researchers have turned their interests to the use of biomass-based raw materials to prepare various materials to replace petroleum as raw materials.In the past research,scholars at domestic and abroad have constructed a“cornerstone”based on related biomass and constructed a large number of functional optical materials by in-situ synthesis or composite with heterogeneous units by using its intrinsic structure and characteristics.The applications of functional optical materials include but not limited to the catalysis,photo-electric energy conversion,biological imaging,optoelectronic devices,seawater desalination,information anti-counterfeiting,etc.In this review,the representative achievements of biomass-based optical functional materials are presented and summarized.Specifically,fabrication and the properties of aromatic biomass-derived fluorescent materials,polysaccharide biomass-derived fluorescent materials,cellulose-based photonic materials and biomass-derived photothermal materials would be systematically introduced and described.The structure-performance correlation would be analyzed in a detailed manner.After that,the selected applications of these aromatic biomass-derived fluorescent materials,polysaccharide biomass-derived fluorescent materials,cellulose-based photonic materials and biomass-derived photothermal materials in sensing food quality,bioimaging,encryption printing,light-emitting devices and light-to-mechanical motion would also be introduced.Finally,the existing problems,such as fluorescence wavelength,photothermal conversion efficiency,etc.in the field and the future development direction are proposed.This review article is expected to provide a detailed evolution mapping of biomass-based optical materials and give inspiration for scientists working on the design of sustainable high performance biomass-derived optical materials. |
