Miniaturized and wearable electronic products require electromagnetic interference shielding (EMI) materials with sensing functions to cope complex application situations. Herein, an effective dual-network structure is designed fabricate two-dimensional transition metal carbides nitrides/bacterial cellulose-thermoplastic polyurethane (MXene/BC-TPU) foams intriguing EMI property piezoelectric ability under both compressive tensile strains. Anisotropic MXene/BC aerogels, as conductive networks, impressive conductivity (1912 S m-1), ultrahigh effectiveness (SE) of 86 dB, absolute SE up 63,608 dB cm2 g-1 can be built by directional freezing. Interpenetrated neuro-like TPU network embedded into the aerogels controllable coagulation provide elasticity. Inheriting elastic network, light weight MXene/BC-TPU show superb elasticity remarkable fatigue resistance suffering strains a wide strain range (-80-80%). Meanwhile, benefiting from separated display outstanding (76 dB) retention 86.8% after 5000 compression-release cycles 69.7% 100 stretch-release cycles, respectively. Furthermore, reveal stable signal output piezoresistive sensors in -80-80%. The highly conductive, stretchable, compressible are suitable motion monitoring for electronics.

Abstract In extreme cold and dynamic environments, active passive ice‐phobic coatings face performance degradation due to surface issues low photoelectric‐thermal conversion. Photothermal solid‐like slippery coating (PSSC) is developed using the “yin‐yang associative elements” idea. By combining low‐thermal‐conductivity microspheres, nano‐porous aerogels, silicone oil, epoxy, PSSC forms a micro‐nano‐nano light‐trapping structure surface. It has 2.6° water sliding angle, 9.2 kPa ice adhesion, an icing delay 79.5 times that of bare aluminium (Al). Moreover, also exhibits excellent corrosion resistance environmental durability. After 30 days ultraviolet (UV) irradiation saltwater immersion, angle increases minimally. Its boosts photothermal performance, heating 148 °C in 20 s under 1 sun irradiation. At –20 °C, it melts fast with Notably, at 80% Relative Humidity (RH), 80 rpm min −1 defrosting test, defrosts 180 s. The can achieve rapid removal within −30 °C. PSSC's ability environments offers new thoughts for advanced development.
