Abstract Phase change materials (PCMs) are pivotal in thermal energy management and conversion applications owing to their exceptional storage release characteristics. However, persistent challenges such as poor conductivity leakage issues have impeded widespread adoption. While existing approaches mitigate these by constructing incorporating 3D conductive networks, they constrained discontinuous preparation methods mold size limitations. Herein, a scalable sol–gel permeation assembly strategy is proposed prepare phase layered film situ filling polyethylene glycol (PEG) aramid nanofibers (ANF)/graphene nanoplates (GNP) network. Befitting from the laminated network encapsulation effect of ANF GNP, demonstrates leak‐free stable transition behavior, even after undergoing 500 heating/cooling cycles. Moreover, resulting PEG/ANF/GNP exhibits an impressive in‐plane 23.7 W mK −1 at GNP loading 28.1 vol.%, rendering it suitable for electronic devices. The possesses photo‐thermal properties, maintaining temperatures exceeding 90 °C under light power density 200 mW cm − 2 . Capitalizing on thermally induced flexibility its temperature‐dependent stiffness, utility extended developing light‐thermal driving gripper.

Abstract Seasonal storage of solar thermal energy through supercooled phase change materials (PCM) offers a promising solution for decarbonizing space and water heating in winter. Despite the high density adaptability, natural PCMs often lack necessary supercooling stable, long-term storage. Leveraging erythritol, sustainable mid-temperature PCM with latent heat, we introduce straightforward method to stabilize its by incorporating carrageenan (CG), bio-derived food thickener. By improving solid-liquid interfacial addition CG heat erythritol can be effectively locked at very low temperature. We show that composite sustain an ultrastable state below −30 °C, which guarantees no accidental loss severe cold regions on Earth. further demonstrate common ultrasonication used as key unlocking stored CG-thickened showing great potential serve high-performance, eco-friendly seasonal

Abstract The emerging concept of aerogel composite phase change materials (PCMs) represents a promising approach for thermal energy storage and utilization. However, the aerogels currently reported usually lack essential properties, thereby constraining their potential functional design advanced applications. Herein, multifunctional with characteristics thermoregulation performance are prepared by chemically crosslinking unidirectional freezing to make functionalized mineral‐based PCMs as cavity walls. Thanks cross–linked continuous skeleton retained hierarchical porous, this novel possesses an 89.7% porosity demonstrates excellent resilience under 80% compression. As in walls can convert phonon transport modes through transitions, has enhanced insulation reaching conductivity 29.6 mW m −1 K . Drawing upon properties aerogels, it is demonstrated that masks comfort health protection, well passive management wrist guards capable harnessing solar radiation temperature regulation. This work encompasses exploration approaches developing cater diverse regulation requirements across various domains.
