The fragility of early inorganic aerogels led to the exploration of organic counterparts, with cellulose aerogels standing out due to their natural abundance, biocompatibility, and tunable properties. Despite inherent limitations like flammability and low thermal stability, recent advancements in cellulose-based hybrid aerogels show promise. These hybrid aerogels, combining cellulose with organic and inorganic components, offer enhanced functionality and tunability. The review covers the historical background, scientific achievements, and the design principles behind cellulose-based hybrid aerogels, exploring their potential impact and future opportunities for improved scalability and multifunctional properties.
