Lightweight Ambient-Dried Biobased Aerogels with Superior Fire Safety and Mechanical Durability for Thermal Insulation

ACS Applied Materials & Interfaces, Год журнала: 2025, Номер unknown

Опубликована: Июнь 1, 2025

Biobased aerogels have emerged as promising thermal-insulation materials, offering a sustainable solution to mitigate global energy consumption. However, achieving with high environmental adaptability that combine thermal resistance, reliable fire safety, structural and mechanical durability, energy-efficient fabrication processes remains significant challenge. Herein, low-carbon aerogel is developed by integrating synergistic carbonization design green ambient drying techniques. Unlike traditional complex freeze-drying or hazardous solvent exchange methods, the strategic combination of thermoresponsive gel fixation mechanical-assisted air templates enables transformation water-based foamy hydrogels into porous via process, in which gellan gum melamine-formaldehyde resin serve carbonizable interpenetrating matrices, while boric acid acts catalytic carbonization/hybridization agent participates molecular cross-linking. The as-developed exhibits an impressive ability provide comprehensive protection various environments, combining rapid self-extinguishment (LOI = 50%), low heat/smoke hazard (30 kW/m2/1.6 m2), excellent resistance (blocking 75.5% heat 1300 °C flame), structural/mechanical durability (93%) harsh environments (e.g., hot water, strong acids/alkalis, chemicals) when featuring lightweight (43 mg/cm3), surpassing previous biobased aerogels. This work provides straightforward integrated approach create high-performance aerogels, showing great commercial potential for massive applications buildings.
