Research Progress and Applications of Cellulose Aerogels

气凝胶凭借其独特的三维网络结构，作为目前已知世界上密度最低且微观尺度极小的固体材料，在材料科学及相关领域引发了广泛关注。纤维素气凝胶无疑是与可持续发展理念相契合的新型材料，它不仅具备高孔隙率和大比表面积等优异特性，还具有可被微生物降解以及与多种物质良好兼容等优势。文章介绍了制作纤体素凝胶的方法，常压干燥，冷冻干燥，超临界干燥等特征论述。在应用上，对纤素气凝胶所展现的广阔前景进行了探索，并展望了它的发展前景。Aerogels, with their unique three-dimensional network structure, have attracted widespread attention in materials science and related fields as the lowest density solid materials known in the world with extremely small microscopic scales. Cellulose aerogels are undoubtedly a new type of material that aligns with the concept of sustainable development; they not only possess excellent characteristics such as high porosity and large specific surface area but also have advantages such as biodegradability and good compatibility with various substances. This article introduces methods for producing cellulose aerogels, discussing features such as ambient pressure drying, freeze-drying, and supercritical drying. In terms of applications, it explores the broad prospects demonstrated by cellulose aerogels and anticipates their future development.to the Hans standard, which illustrates all the formats.
