“…Moreover, when the external force was removed, the spacer yarns behaved like mini springs standing upright, facilitating elastic recovery. [ 48 ] In summary, the outstanding photothermal, water management performance, and favorable mechanical properties of rGO‐SA‐PSF laid a solid foundation for achieving efficient and stable seawater desalination.…”

Interfacial solar steam generators (ISSGs) can capture solar energy and concentrate the heat at the gas–liquid interface, resulting in efficient water evaporation. However, traditional ISSGs have limitations in long‐term seawater desalination processes, such as limited light absorption area, slow water transport speed, severe surface salt accumulation, and weak mechanical performance. Inspired by lotus seedpods, a novel ISSG (rGO‐SA‐PSF) is developed by treating a 3D warp‐knitted spacer fabric with plasma (PSF) and combining it with sodium alginate (SA) and reduces graphene oxide (rGO). The rGO‐SA‐PSF utilizes a core‐suction effect to achieve rapid water pumping and employs aerogel to encapsulate the plasma‐treated spacer yarns to create the lotus seedpod‐inspired hydrophilic stems, innovatively constructing multiple directional water transport channels. Simultaneously, the large holes of rGO‐SA‐PSF on the upper layer form lotus seedpod‐inspired head concave holes, enabling efficient light capture. Under 1 kW m−2 illumination, rGO‐SA‐PSF exhibits a rapid evaporation rate of 1.85 kg m−2 h−1, with an efficiency of 96.4%. Additionally, it shows superior salt tolerance (with no salt accumulation during continuous evaporation for 10 h in 10% brine) and self‐desalination performance during long‐term seawater desalination processes. This biomimetic ISSG offers a promising solution for efficient and stable seawater desalination and wastewater purification.

“…However, the thermal conductivity of SPS-HM is slightly inferior to that of SP composites with a hierarchically porous structure but without spacer yarns for heat transfer. 33,34 Figure 4(d) shows the flame retardancy test results of the samples. It can be found that the PU is burnt extremely rapidly after placing on the Bunsen burner, while a large amount of black smoke is simultaneously emitted.…”

To effectively overcome the shortcomings of common polyurethane (PU) insulation materials in terms of flame retardancy, mechanical properties, and sound absorption, a new multi-functional insulation material needs to be developed. Here, simple materials such as PU and silica aerogel (SA) combined with a special three-dimensional spacer fabric were used to design an innovative SA/PU/spacer fabric (SPS) ternary composite. It integrates a “hierarchically porous” and “filled-microperforated plate” structure. The superior structure design endows the new type of composite with a remarkable performance while maintaining low density (0.198 g/cm3). Specifically, the SPS composite was difficult to ignite by alcohol lamps compared with PU and SA/PU, and its thermal conductivity and compression modulus can reach 0.0392 W/(m·k) and 1.5 MPa, respectively. Moreover, the average absorption coefficient of the SPS composite (7.5 mm thickness) is 0.62, and its noise reduction coefficient per unit thickness (0.37) exceeds most reported sound absorption materials. From these results, the SPS composite provides a convenient and low-cost method to improve the overall performance of traditional thermal insulation material, which is of great significance in the fields of construction and transportation.
