Abstract Stimuli‐responsive hydrogels hold significant promise for human‐machine communication and soft actuators. However, conventional hydrogels, lack inherent rigidity render them incapable of withstanding the external stress concentration, leading to severe structural destruction. To address this limitation, a structurally integrated hydrogel (SIG) based on coordination bonding‐assisted heterostructure design is developed, combining PEDOT:PSS/polyacrylic acid layer rigid TEMPO‐oxidized bacterial cellulose controllable Notably, molecular dynamics simulation reveals that abundant interface interlocking scaffold effectively mitigates crack propagation optimizes integrity.

Meanwhile, contributes programmable reversible auto‐deformation (≈120 s) shape memory (flower gripper). Furthermore, integration with screen‐printed Ag interdigital electrodes enables development smart gripper device capable providing continuous haptic feedback, enhancing its functionality in interactive applications.

Abstract Excessive electromagnetic pollution caused by waves can interfere with the normal use of electronic devices or cause unnecessary damage to human health. Although conductive polymer composites (CPCs) are used replace traditional metals as an effective strategy for managing undesirable waves, CPCs have a non‐negligible trade‐off in enhancement interference (EMI) shielding effectiveness and absorption coefficient because their reflection‐dominated EMI mechanism. Therefore, alleviate secondary pollution, absorption‐dominated asymmetric structures urgently needed. Recently, structural designs advanced significantly, but seldom been summarized discussed detail. Consequently, this review first systematically summarizes current progress after brief clarification about necessity configuration structure design. Afterward, various fiber, layered, porous, composite described. Besides, versatility is briefly introduced. Finally, challenges prospects proposed guide future advancement field.

Although materials with infrared camouflage capabilities are increasingly being produced, few applications exist in clothing fabrics. Here, graphene/MXene-modified fabric superior camouflage, Joule heating, and electromagnetic shielding all one was prepared by simply scraping a graphene slurry onto alkali-treated cotton fabrics, followed spraying MXene. The functionality of the modified fabrics after different treatment times then tested analyzed. results indicate that mid-infrared emissivity decreases an increase coating When at loads 5 1.2 mg/cm2, respectively, have very low 3–5 8–14 μm bands, surface temperature can be reduced 53.1 °C when placed on heater 100 (surface radiation 95 °C). also demonstrates excellent heating capabilities; 4 V power, 91.7 may reached 30 s. In addition, customized exhibit strong performance. By folding cloth, interference shield effect increased to 64.3 dB. With their thermal management, performance, found extensive use intelligent wearables military applications.
