Biopolymer aerogels were among the first aerogels produced, but only in the last decade has research on biopolymer and biopolymer-composite aerogels become popular, motivated by sustainability arguments, their unique and tunable properties, and ease of functionalization. Biopolymer aerogels and open-cell foams have great potential for classical aerogel applications such as thermal insulation, as well as emerging applications in filtration, oil-water separation, CO capture, catalysis, and medicine. The biopolymer aerogel field today is driven forward by empirical materials discovery at the laboratory scale, but requires a firmer theoretical basis and pilot studies to close the gap to market. This Review includes a database with over 3800 biopolymer aerogel properties, evaluates the state of the biopolymer aerogel field, and critically discusses the scientific, technological, and commercial barriers to the commercialization of these exciting materials.
生物聚合物气凝胶是最早生产的气凝胶之一，但直到最近十年，生物聚合物和气凝胶复合材料的研究才变得热门，这是出于可持续性论点、其独特和可调的性质以及易于功能化的动机。生物聚合物气凝胶和开孔泡沫在经典气凝胶应用（如隔热）以及新兴应用（如过滤、油水分离、CO 捕获、催化和医学）方面具有巨大潜力。今天，生物聚合物气凝胶领域由实验室规模的经验材料发现推动，但需要更坚实的理论基础和试点研究来缩小与市场的差距。本综述包括一个拥有超过 3800 种生物聚合物气凝胶特性的数据库，评估了生物聚合物气凝胶领域的现状，并批判性地讨论了这些令人兴奋的材料商业化面临的科学、技术和商业障碍。
