Silicone-based elastomers (SEs) have been extensively applied in numerous cutting-edge areas, including flexible electronics, biomedicine, 5G smart devices, mechanics, optics, soft robotics, etc. However, traditional strategies for the synthesis of polymer elastomers, such as bulk polymerization, suspension solution and emulsion are inevitably restricted by long-time usage, organic solvent additives, high energy consumption, environmental pollution. Here, we propose a Joule heating chemistry method ultrafast universal fabrication SEs with configurable porous structures tunable components (e.g., graphene, Ag, graphene oxide, TiO 2 , ZnO, Fe 3 O 4 V 5 MoS BN, g-C N BaCO CuI, BaTiO polyvinylidene fluoride, cellulose, styrene-butadiene rubber, montmorillonite, EuDySrAlSiO x ) within seconds only employing H solvent. The intrinsic dynamics situ polymerization porosity creation these widely investigated. Notably, capacitive sensor made from as-fabricated silicone-based exhibits wide pressure range, fast responses, long-term durability, extreme operating temperatures, outstanding applicability various media, wireless human–machine interaction system used rescue activities conditions is established, which paves way more polymer-based material wider applications.

Abstract Flexoelectricity, a universal electromechanical coupling phenomenon, has triggered new feasibilities of advancements in functional materials, especially for nanoscale materials. The strong flexoelectric response is initially discovered ceramic materials with high permittivity, and then the past decades have witnessed expansion flexoelectricity to broader range material systems including semiconductors, polymers, soft elastomers, which turn raise emerging applications flexoelectricity. Moreover, demonstrated be significantly enhanced thin films nanostructures where ultra‐high strain gradients are easier achieve, rendering attractive modifying properties advanced devices at nanoscale. To provide comprehensive drawing above aspects, this review highlights recent progress diverse covering characterization flexoelectricity, fundamental mechanisms enhancement as well multi‐functional applications. Finally, some open questions perspectives presented, underlining fascinating future field.

In aerogel-based thermal insulation materials, the challenge of balancing mechanical properties (rigidity and flexibility) while enhancing performance under extreme temperature humidity conditions persists. This study introduces an innovative biomimetic aerogel design combining features shell-like layered architecture loofah porous microstructures. We developed polyimide/polyvinylidene fluoride (PI/PVDF) nanofiber aerogels with excellent properties. The material can withstand compressive loads up to 1500 times its weight axial rigidity, maintaining radial flexibility 80% strain, thereby achieving a harmonious balance between structural rigidity flexibility. inclusion hydrophobic PVDF nanofibers ensures maintains low conductivity integrity, even changes. multifeature fusion shows great potential for aerospace applications, such as spacecraft protection systems, effectively shielding components from stress during re-entry space missions.

Abstract Biomass‐based multifunctional hydrogels with high mechanical strength, fatigue resistance, and electrical conductivity are promising materials for the fabrication of flexible electronic devices. However, achieving mutually exclusive properties simultaneously remains challenging. Herein, a novel luffa sponge (LS) composite multi‐functional hydrogel (WLSHG) is prepared. The LS dignified to create 3D skeleton, which then polymerized polyacrylamide in situ using tannic acid–ferric ions reoxidation system. Benefiting from strong physical support skeleton multiple interactions between molecules system, synergistically enhanced hydrogel. compressive strength modulus WLSHG increased by 557% 2000%, respectively, compared pristine hydrogels. And honeycomb‐like microchannels bundle facilitated efficient ion transport, resulting an ionic 0.124 S m −1 WLSHG. WLSHG‐based strain sensor exhibited excellent sensitivity (2.03 kPa ) stability (>1000 cycles) over wide pressure range. By integrating this into array Internet Things machine learning technologies, its ability successfully demonstrated accurately recognize human sitting position gait patterns.
