Abstract Intelligent electromagnetic interference (EMI) shielding materials, with their tunable EM wave response characteristics, have attracted much attention. However, the molecular‐level mechanism is under‐explored and tuning range narrow. This study proposes an EMI switch hydrogel based on molecular precision manipulation of a thermoresistive network capable adaptively regulating performance. It has two temperature‐controlled switching states: on/off strong/weak shielding. The consists interpenetrating polyvinyl alcohol (PVA) poly(N‐isopropylacrylamide) (PNIPAM) networks, giving it thermal shrinkable properties. A temperature‐induced high contact resistance MXene‐carbon nanotubes (MXene‐CNTs) conductive assembled within it. combination enables to switchable performance in X‐band, 9.3–53.9 dB at different temperatures or thicknesses. remarkable results from synergistic effect temperature‐driven shrinkage matrix network, involving adjustments particle stacking, conductivity, transmission path.

The exceptional electrical conductivity and efficient heat transfer efficiency of multiwalled carbon nanotubes (MWCNTs) make them an ideal material for flexible transparent films, which require a combination these properties. Nevertheless, the regulation light transmittance in MWCNT films presents significant technical challenges. This paper proposes method fabricating with embedded MWCNTs grid electrode structures based on UV imprinting scraper filling processes. electrothermal properties are regulated by design dimensions. For cavity depth 23 μm, opening size 100 width 6 temperature can be increased to 106 °C at 30 V. Concurrently, transmission was observed 87.6%. exhibit robust mechanical stability under diverse bending radii repeated cyclic tests. Moreover, film is capable not only precise control but also monitoring change characteristics fluorescent materials real-time.

Supercapacitors have emerged as a popular area of research due to their exceptional attributes, including excellent cycling life, admirable power density, and rapid charge/discharge capabilities. However, the low energy density significantly restricts its range applicable scenarios. Herein, grafting copolymerization technique was employed incorporate transition metals (nickel, cobalt) into molecular chain lignin, lignin-based pseudocapacitor material (Ni/Co@LC) is obtained after thermal treatment. XRD, X-ray photoelectron spectroscopy, scanning electron microscopy, dispersive spectrometry results demonstrate strong interaction between Ni/Co carbon, with encapsulated within carbon shell. Hence, Ni/Co@LC exhibits an approximately 69% increase in specific capacitance compared those conventional materials which coated on surface materials, equivalent series resistance reduced by about 50%. Moreover, assembled asymmetric supercapacitors Ni/Co@LC//LC achieve 52.89 W h kg-1 at 640 maintain retention rate 99.28% undergoing 10,000 charge-discharge cycles. This work presents novel approach for designing electrode impedance high performance.

Abstract Nickel oxyhydroxide based energy storage materials have been largely confined by insufficient exposure of active sites which results in low efficiency and poor stability. In order to resolve the problems, hierarchical flower array heterostructure NiCoOOH@CoLa‐LDH (denoted as NC@CL) nanosheets are designed with NiCo (NiCoOOH, denoted NC) being tightly covered on CoLa layered double hydroxide (CoLa‐LDH, CL) nanosheet. This rational design creates more sites, enlarges electrode‐electrolyte contact area, improves electron conductivity, prevents agglomeration during cycling charge–discharge processes. Density functional theory calculations differential charges concurrently illustrate that formation optimizes reaction kinetics promotes redistribution. Benefiting from heterogeneous structure rich electro‐active caused NC, NC@CL displays outstanding reversible specific capacitance (3228 F g −1 at 1 A ). The aqueous rechargeable alkaline Zn battery NC@CL//Zn exhibits a high capacity 381.1 mA h 0.5 durability (98% retention after 5 for 2000 cycles). excellent electrochemical performances indicate has great application potential electrode material device.
