“…The hysteresis loops indicate the energy dissipation during the compression and recovery process, which may be caused by the buckling of porous microstructures and the macromolecular friction. 55 Figure 5b shows the cyclic stress−strain curves, and it is found that these curves possess similar profiles and the stress at the maximum strain (ε = 50%) keeps almost the same at the end of each cyclic test, demonstrating the outstanding recyclability. The compressive stress of the pristine sponge and its composites is summarized in Figure 5c.…”

Flexible strain or pressure sensors have potential applications in electronic skin, healthcare, etc. It remains a challenge to explore multifunctional strain or pressure sensors that possess excellent water repellent and heating performance and hence can be used in harsh environments such as high moisture and low-temperature conditions. Here, a self-derived superhydrophobic and multifunctional polymer composite foam is prepared by adsorption of the Ag precursor in tetrahydrofuran (THF) onto the rubber sponge followed by reduction of Ag + to Ag nanoparticles (AgNPs). During the Ag + reduction in hydrazine solution, the swollen rubber sponge by THF is partially precipitated based on the nonsolvent-induced phase separation (NIPS). The NIPS creates a porous structure on the sponge surface and thus a high surface roughness, contributing to the material superhydrophobicity. The precipitated polymer wrapping the AgNPs could enhance the interaction between the individual AgNPs. The obtained conductive sponge composite possesses excellent Joule heating and photothermal performance and can be used as both a strain and pressure sensor. The conductive sponge composite sensor possesses good reliability and durability and can be applied to real-time monitoring of human body movements.

“…Due to its low density (0.10~1 g cm −3 ), high porosity (60~90%), low thermal conductivity (<1 W m −1 k −1 ), and excellent high-temperature stability, it is widely used in the field of thermal insulation [ 1 , 2 , 3 , 4 , 5 , 6 ]. At present, the main preparation methods of CBCF composites are vacuum filtration, pressure filtration, and whole needle-punching method [ 7 , 8 , 9 , 10 ]. The vacuum filtration method or pressure filtration method has been developed because of its simplicity and efficiency.…”

Lightweight, high-temperature-resistant carbon-bonded carbon fiber (CBCF) composites with excellent thermal insulation properties are desirable materials for thermal protection systems in military and aerospace applications. Here, glucose was introduced into the polyacrylamide hydrogel to form the glucose-polyacrylamide (Glu-PAM) hydrogel. The CBCF composites were prepared using the Glu-PAM hydrogel as a brand-new binder, and the synergistic effect between glucose and acrylamide was investigated. The results showed the Glu-PAM hydrogel could limit the foaming of glucose and enhance the carbon yield of glucose. Meanwhile, the dopamine-modified chopped carbon fiber could be uniformly mixed by high-speed shearing to form a slurry with the Glu-PAM hydrogel. Finally, the slurry was successfully extruded and molded to prepare CBCF composites with a density of 0.158~0.390 g cm−3 and excellent thermal insulation performance and good mechanical properties. The compressive strength of CBCF composites with a density of 0.158 g cm−3 in the Z direction is 0.18 MPa, and the thermal conductivity in the Z direction at 25 °C and 1200 °C is 0.10 W m−1 k−1 and 0.20 W m−1 k−1, respectively. This study provided an efficient, environment-friendly, and cost-effective strategy for the preparation of CBCF composites.

“…Aerospace products often use multilayer structures to resist extreme temperature differences and solar radiation in space. Although multilayer structures can protect against multiple threats, a single multifunctional material can reduce the load-bearing weight and manufacturing complexity [ 1 , 2 ]. Traditional thermal insulation and mechanical energy dissipation mechanisms compete with each other, so an effective composite of material structures is needed to break this competition mechanism [ 2 ].…”

Flame-retardant, thermal insulation, mechanically robust, and comprehensive protection against extreme environmental threats aerogels are highly desirable for protective equipment. Herein, inspired by the core (organic)-shell (inorganic) structure of lobster antenna, fire-retardant and mechanically robust aramid fibers@silica nanocomposite aerogels with core-shell structures are fabricated via the sol-gel-film transformation and chemical vapor deposition process. The thickness of silica coating can be well-defined and controlled by the CVD time. Aramid fibers@silica nanocomposite aerogels show high heat resistance (530 °C), low thermal conductivity of 0.030 W·m−1·K−1, high tensile strength of 7.5 MPa and good flexibility. More importantly, aramid fibers@silica aerogels have high flame retardancy with limiting oxygen index 36.5. In addition, this material fabricated by the simple preparation process is believed to have potential application value in the field of aerospace or high-temperature thermal protection.
