Hierarchically Engineered Nanocellulose-Halloysite Composite Foams for Integrated Thermal Insulation and Intrinsic Fire Resistance.
Achieving the simultaneous integration of thermal insulation, mechanical robustness, hydrophobicity, and intrinsic flame retardancy in bio-based porous materials remains a major challenge. Here, we report a hierarchically engineered nanocomposite foam composed of nanofibrillated cellulose (NFC), alkyl ketene dimer (AKD...
