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 With their low density and high porosity, aerogels are widely used as supporting frameworks for phase change materials (PCMs). However, the host–guest solid–liquid phase‐change systems often encounter difficulties in optimizing balance between mechanical properties thermal energy storage performance, intrinsic advantages of not being fully realized. Herein, an aerogel‐functionalization‐PCM strategy, a completely converse route compared to traditional aerogel‐filling‐PCM method, toward lightweight, flexible PCM robust management is developed. As proof concept, silica aerogel particles (SAPs) functional components added polyvinyl alcohol‐polyethylene glycol network produce composite PCMs. The addition SAP reduces PCM's latent heat by 25% but significantly decreases heating rate 190% enhances insulation 147%, achieving 28 °C temperature drop at 80 °C. This work provides fresh perspective on design thermally PCMs demonstrates feasibility enhancing protection under reduced conditions.

Owing to the significant latent heat generated at constant temperatures, phase change fibers (PCFs) have recently received much attention in field of wearable thermal management. However, materials involved existing PCFs still experience a solid-liquid transition process, severely restricting their practicality as management materials. Herein, we, for first time, developed intrinsically flexible (polyethylene glycol/4,4'-methylenebis(cyclohexyl isocyanate) fibers, PMFs) through polycondensation and wet-spinning exhibiting an inherent solid-solid property, adjustable behaviors, outstanding knittability. The PMFs also present superior mechanical strength (28 MPa), washability (>100 cycles), cycling stability (>2000 facile dyeability, heat-induced recoverability, all which are highly practical applications. Additionally, can be easily recycled by directly dissolving them solvents reprocessing, revealing promising applications sustainable Most importantly, applicability was demonstrated knitting into permeable fabrics, exhibit considerably improved performance compared with cotton fabric. offer great potential intelligent regulation smart textiles electronics.

As microelectronics technology advances towards miniaturization and higher integration, the imperative for developing high-performance thermal management materials has escalated. Thermal conductive polymer composites (TCPCs), which leverage benefits of matrices unique effects nano-enhancers, are gaining focus as solutions to overheating due their low density, ease processing, cost-effectiveness. However, these often face challenges such conductivities that lower than expected, limiting application in electronic devices. Despite issues, TCPCs continue demonstrate broad potential across various industrial sectors. This review comprehensively presents progress this field, detailing mechanisms conductivity (TC) discussing factors influence performance, intrinsic properties polymers, interfacial resistance, fillers. Additionally, it categorizes summarizes methods enhance TC composites. The also highlights applications emerging areas flexible devices, personal management, aerospace. Ultimately, by analyzing current opportunities, provides clear directions future research development.
