“…The obtained tensile stress–strain and compressive stress–strain curves are displayed in Figures f and S8. It can be seen that the SBF aerogel and the SBFAP material exhibited high ultimate tensile strengths, the values being 53 and 64 kPa, respectively . The ultimate tensile strengths of the fabricated materials were equivalent to those of other aerogels. − This can be attributed to the hydrogen bonds between PVA and CFB, which produced the tight crosslinked system, thus enhancing the reinforcement capability.…”

Aerogels are becoming a promising platform to fabricate photothermal materials for use in solar steam generation (SSG), which have remarkable application potential in solar desalination, due to their excellent thermal management, salt resistance, and considerable water evaporation rate. In this work, a novel photothermal material is fabricated by forming a suspension between sugarcane bagasse fibers (SBF) and poly(vinyl alcohol), tannic acid (TA), and Fe 3+ solutions via hydrogen bonds of hydroxyl groups. After freeze drying, the fabricated SBF aerogel-based photothermal (SBFAP) material possesses a 3D interconnected porous microstructure, which could enhance water transportation ability, reduce thermal conductivity, and quickly dissolve salt crystals on the SBFAP surface. Thanks to the formation of micro/nanosized complexes between TA and Fe 3+ ions on the SBFAP material, the SBFAP exhibits high light capture and water evaporation rate (2.28 kg m −2 h −1 ). In particular, due to strong hydrogen bonding and the SBF, the SBFAP material is reinforced, thereby exhibiting excellent structural stability in seawater. Moreover, the high salt tolerance of SBFAP favors its high desalination performance for at least 76 days of continuous evaporation under actual conditions. This research paves the way for the fabrication of natural cellulose fiber-based photothermal materials for application in solar desalination.

“…At a fracture strain of 82.63%, the maximum compression stress of H2F-SA is as high as 26.40 MPa (Figure b). In terms of the compression specific strength and fracture strain, H2F-SA is superior to other aerogels with excellent mechanical properties (Figure c), ,,− emphasizing its excellent mechanical resistance to compression. Also, with this special structure, H2F-SA also achieves the coexistence of high strength and excellent processability.…”

Conventional SiO 2 aerogels composed of 0-dimensional nanoparticles do not have large-scale compression, tensile, and shear deformation capabilities, and the poor mechanical properties hinder their further development and application. We report a scalable strategy to construct the nanoporous network of a SiO 2 aerogel by alternately linking octa(aminophenyl)-T8-POSS and hexaphthalic acid. The resulting SiO 2 aerogel exhibits high strengths (compression, tensile and shear strengths are 26.4, 9.16, and 8.31 MPa, respectively), excellent deformabilities (fracture compression, tensile, and shear strains are 82.63%, 57.81% and 108.02%, respectively), flexbile processability and good structural stability (only 1.7% plastic deformation occurs after 100 load−unload cycles at a large compression strain of 70%). Also, the mesoporous interconnected nanoskeleton with high porosity and the composition of fully hydrophobic groups also give the aerogel low thermal conductivities (0.02854 W/(m K) at 25 °C and 0.04638 W/(m K) at 300 °C) and superhydrophobic properties (hydrophobic angle 160°and saturated mass moisture absorption rate about 0.375%). The combination of these excellent properties ensures that the aerogel can be used as an efficient thermal insulation material for extreme environments, such as those where comprehensive mechanical and hydrophobic properties are strictly required.
