Abstract Developing high‐performance infrared (IR) radiation materials with desired broadband emissivity, excellent thermal stability, and scalable fabrication processes is highly desirable for energy‐saving applications heat dissipation. However, it remains a grand challenge to concurrently meet these requirements in existing IR materials. Herein, high‐entropy (HE) approach employed advance the performance of spinel oxide. This strategy efficiently narrows bandgap due enhanced electron transitions introduction oxygen vacancies (O v ), variable‐valence behavior, orbital hybridization. In addition, lattice distortion effect lowers symmetry vibration. Therefore, resulting HE oxide exhibits near‐blackbody performance, its emissivity approximately three times higher than that binary Moreover, entropy‐dominating phase stabilization contributes impressive stability (stable at 1300 °C 100 h). makes suitable high‐temperature applications, such as energy conservation industrial furnaces. More importantly, can be readily spray‐coated on various substrates. And coating stainless steel reaches an outstanding 0.943 0.78−16 µm wavelength range. All merits render competitive development high‐emissivity thermally stable

Abstract Graphene‐skinned fiber fabric is prepared by chemical vapor deposition (CVD) of continuous graphene on fabric, which enables conformal coverage fibers and inherits high electrical thermal conductivity graphene. However, in the fabric‐shaped configuration, contact resistances between fibers, lack conductive pathways along radial direction limit improvement conductivity. Herein, carbon nanotubes (CNTs), due to 1D structure with excellent conductivity, are introduced build rich “bridges” connect isolated new electron phonon transport channels. Thus, conceptual design CNT/graphene‐skinned glass (CNT/GGFF) creatively proposed realized a carefully designed CVD. Constructing 3D electrically thermally network CNT/GGFF leads >90% decrease sheet resistance, 4.5 times increase tensile strength, >70% resistance compared GGFF, making it promising for applications composite materials, heat dissipation, de‐icing. Moreover, exhibits temperature‐independent, extending aviation space because changes traditional materials environmental temperatures can adversely affect stability, reliability, lifetime aircrafts.

Abstract Effective heat dissipation is critical for high‐power modules amid increasing demands compact, lightweight, and high‐performance electronic devices. This study presents a passive cooling strategy employing type of hierarchical resin‐free coating (HRC) on the etched surfaces pipe radiator modules. The HRC consists graphene‐hybridized hexagonal boron nitride ( h ‐BN) nanosheet networks fabricated via scalable three‐step chemical etching substrate, ball‐milling exfoliation, silane coupling process. It achieves an infrared emissivity 0.97, owing to strong phonon vibrations within 2D nanosheets localized surface plasmon resonance from micro/nanostructures which induce electromagnetic field polarization, as confirmed by numerical simulation. Heat performance coated with HRC, compared uncoated one, apparently improved due enhanced radiative cooling. Experimental results demonstrate that coatings, relative yields 3.1–9.9 °C temperature reduction at air velocities 1–5 m s −1 decrease total thermal resistance up 16.7% under 1.5 kW load. work provides new design concept environmentally friendly, highly efficient, sustainable management solutions in
