“…As a natural fiber, cotton fabric with low cost and high yield has been widely used in industries and households owing to comfort, softness, breathability, wash resistance and moisture absorption. 23,24 Modifying cotton fabrics to be superhydrophobic will expand their applications in oil-water separation [25][26][27][28] and self-cleaning, [29][30][31] thus many representative methods have emerged including, spray-coating, 32 phase separation, 33 layerby-layer self-assembly, and chemical vapor deposition. 34 However, there are many issues in the above methods such as complicated preparation process, expensive equipment, long reaction time, and toxic fluorine-containing low-surface-energy material, restricting large-scale applications.…”

“…The HGC aerogel will be used for a long time in flammable and explosive places, such as oil/organic solvent absorption or thermal insulation, where fire accidents have occasionally occurred in recent years. , Therefore, the HGC aerogel should have high flame retardancy to ensure the safety of practical applications. , As shown in Figure g, the HGC aerogel was difficult to be ignited in the air and immediately extinguished after the removal of fire, indicating excellent fire safety. Actually, the aerogel exhibits a high limiting oxygen index value of 28%, compared to 17% of commercial polyurethane foam.…”

Biomass aerogels are highly attractive candidates in various applications due to their intrinsic merits of high strength, high porosity, biodegradability, and renewability. However, under low-temperature harsh conditions, biomass aerogels suffer from weakened mechanical properties, become extremely brittle, and lose functionality. Herein, we report a multifunctional biomass aerogel with lamella nanostructures (∼1 μm) fabricated from cellulose nanofibers (∼200 nm) and gelatin, showing outstanding elasticity from room temperature to ultralow temperatures (repeatedly bent, twisted, or compressed in liquid nitrogen). The resultant aerogel exhibits excellent organic solvent absorption, thermal infrared stealth, and thermal insulation performance in both normal and extreme environments. Even at dry ice temperature (−78 °C), the aerogel can selectively and repeatedly absorb organic solvents in the same way as room temperature with high capacities (90–177 g/g). Excellent heat insulation and infrared stealth performances are achieved in a wide temperature range of −196 to 80 °C. Further, this aerogel combines with the advantages of ultralow density (∼6 mg/cm3), biodegradability, flame retardancy, and performance stability, making it a perfect candidate for multifunctional applications under harsh conditions. This work greatly broadens application temperature windows of biomass aerogels and sheds light on the development of mechanically robust biomass aerogels for various applications under extreme conditions.

“…However, the curves of RPUF-T15, RPUF-T30 and RPUF-T45 show P 2p besides C 1s , N 1s , and O 1s , and the peaks of P 2p became surely obvious from RPUF-T15 to RPUF-T45, which resulted from the increasing additive amount of TBPBP. In the P 2p spectra, the peak at 133.7 eV was assigned to the P-O-C group [19]. Si2s and Si2p were found in the curve of RPUF-SA20 due to the addition of SA powder.…”

Rigid polyurethane foams (RPUFs) are widely used in many fields, but they are easy to burn and produce a lot of smoke, which seriously endangers the safety of people’s lives and property. In this study, tetraethyl(1,5–bis(bis(2–hydroxypropyl)amino)pentane–1,5–diyl)bis(phosphonate) (TBPBP), as a phosphorus–nitrogen–containing reactive–type flame retardant, was successfully synthesized and employed to enhance the flame retardancy of RPUFs, and silica aerogel (SA) powder was utilized to reduce harmful fumes. Castor oil–based rigid polyurethane foam containing SA powder and TBPBP was named RPUF–T45@SA20. Compared with neat RPUF, the obtained RPUF–T45@SA20 greatly improved with the compressive strength properties and the LOI value increased by 93.64% and 44.27%, respectively, and reached the V–0 rank of UL–94 testing. The total heat release (THR) and total smoke production (TSP) of RPUF–T45@SA20 were, respectively, reduced by 44.66% and 51.89% compared to those of the neat RPUF. A possible flame–retardant mechanism of RPUF–T45@SA20 was also proposed. This study suggested that RPUF incorporated with TBPBP and SA powder is a prosperous potential composite for fire and smoke safety as a building insulation material.
