摘要
全球人口增长和工业化加剧了不可再生能源危机和环境问题,从而激发了对生产环保材料的巨大需求。通常,以生物质材料为主要成分的生物质气凝胶(BAs)因其生物相容性、可降解性和可再生性等优异特性,在各个领域都显示出巨大的应用前景。为了提高生物质吸附剂的性能以满足不同应用场景的使用要求,过去几十年来,大量创新工作都强调了微观结构设计在调节宏观功能方面的重要性。受自然界从微观到中观和宏观尺度无处不在的随机或规则排列材料结构的启发,即使生物分子组成相似,构建不同的微观结构往往对应着完全不同的功能。本综述从凝胶骨架和孔隙结构的角度,重点介绍了具有不同多孔结构的生物碱的制备过程、设计理念、调控方法以及化学成分与微结构的协同组合。不仅全面介绍了各种微结构对 BA 物理性质的影响,还分析了 BA 在热管理、水处理、大气水收集、二氧化碳吸收、能量存储和转换、电磁干扰(EMI)屏蔽、生物应用等相应领域的潜在应用。最后,我们就生物曝气阱面临的挑战和未来的机遇提出了自己的看法。总之,我们的目标是通过对现有数据的全面分析,让研究人员透彻地了解 BA 的微观结构与性能之间的关系。
Renewable biomass-based aerogels: from structural design to functional regulation.
Global population growth and industrialization have exacerbated the nonrenewable energy crises and environmental issues, thereby stimulating an enormous demand for producing environmentally friendly materials. Typically, biomass-based aerogels (BAs), which are mainly composed of biomass materials, show great application prospects in various fields because of their exceptional properties such as biocompatibility, degradability, and renewability. To improve the performance of BAs to meet the usage requirements of different scenarios, a large number of innovative works in the past few decades have emphasized the importance of micro-structural design in regulating macroscopic functions. Inspired by the ubiquitous random or regularly arranged structures of materials in nature ranging from micro to meso and macro scales, constructing different microstructures often corresponds to completely different functions even with similar biomolecular compositions. This review focuses on the preparation process, design concepts, regulation methods, and the synergistic combination of chemical compositions and microstructures of BAs with different porous structures from the perspective of gel skeleton and pore structure. It not only comprehensively introduces the effect of various microstructures on the physical properties of BAs, but also analyzes their potential applications in the corresponding fields of thermal management, water treatment, atmospheric water harvesting, CO2 absorption, energy storage and conversion, electromagnetic interference (EMI) shielding, biological applications, etc. Finally, we provide our perspectives regarding the challenges and future opportunities of BAs. Overall, our goal is to provide researchers with a thorough understanding of the relationship between the microstructures and properties of BAs, supported by a comprehensive analysis of the available data.
