Luffa-Sponge-Structured Silica/Polyimide Composite Aerogels with Integrated Ultra-Strong Mechanics, Superhydrophobicity, and Exceptional Flame Retardancy
Traditional silica aerogels suffer from inherent brittleness and insufficient mechanical properties, which severely restrict their large-scale applications in high-end thermal insulation and flame retardancy. Aiming at low-cost industrialization, we employ cost-effective sodium silicate as the silicon source and hexame...
