ABSTRACT Bio-based aerogels, which are poised as compelling thermal insulators, demand intricate synthesis procedures and have limited durability under harsh conditions. The integration of smart stimuli–response transitions in biomass aerogels holds promise a solution, yet remains challenge. Here, we introduce pioneering strategy that employs reversible-gel-assisted ambient-pressure drying without organic solvents to craft multifunctional bio-based aerogels. By exploiting the thermally reversible gelling propensity select biomasses, anchor emulsified bubbles within cross-linked hydrogels, circumventing surface tension issues during mild drying. resultant feature robust porous matrix is imbued with stable bubbles, yielding low conductivity, high flame retardancy resistance diverse rigors. This innovative approach facilitates paradigm shift intelligent fire protection transition from flexible response water stimuli, effectively shielding against hazards external forces. work opens up facile, eco-friendly way fabricate advanced stimuli-responsive transformation.
