Abstract Phase change materials (PCMs) offer a promising solution to address the challenges posed by intermittency and fluctuations in solar thermal utilization. However, for organic solid–liquid PCMs, issues such as leakage, low conductivity, lack of efficient solar-thermal media, flammability have constrained their broad applications. Herein, we present an innovative class versatile composite phase (CPCMs) developed through facile environmentally friendly synthesis approach, leveraging inherent anisotropy unidirectional porosity wood aerogel (nanowood) support polyethylene glycol (PEG). The modification process involves incorporation phytic acid (PA) MXene hybrid structure evaporation-induced assembly method, which could impart non-leaking PEG filling while concurrently facilitating conduction, light absorption, flame-retardant. Consequently, as-prepared wood-based CPCMs showcase enhanced conductivity (0.82 W m −1 K , about 4.6 times than PEG) well high latent heat 135.5 kJ kg (91.5% encapsulation) with durability stability throughout at least 200 heating cooling cycles, featuring dramatic conversion efficiency up 98.58%. In addition, synergistic effect MXene, flame-retardant performance has been significantly enhanced, showing self-extinguishing behavior. Moreover, excellent electromagnetic shielding 44.45 dB was endowed CPCMs, relieving contemporary health hazards associated waves. Overall, capitalize on exquisite cell transport development multifunctional showcasing operational principle proof-of-concept prototype system.

A MXene/poly(dimethyl diallyl ammonium chloride) (PDDA)/Fe3O4 (MPF) hybrid with exceptional oxidation resistance was synthesized via electrostatic self-assembly. Subsequently, a magnetic field utilized to construct the parallel-aligned MPF within waterborne epoxy coating (WEC). This could significantly hinder penetration of corrosive ions. The electrochemical impedance spectroscopy (EIS) results revealed that WEC containing (VMPF/WEC) exhibited highest low-frequency modulus (|Z0.01 Hz|) among all coatings, which 3 orders magnitude higher than in initial stage corrosion. After 42 days corrosion, |Z0.01 Hz| VMPF/WEC surpassed by more 2 magnitude, thereby indicating long-term corrosion VMPF/WEC. work proposed novel ideas for constructing high-performance anticorrosion WECs.

Abstract The microstructure design for thermal conduction pathways in polymeric electrical encapsulation materials is essential to meet the stringent requirements efficient management and runaway safety modern electronic devices. Hence, a composite with three-dimensional network (Ho/U-BNNS/WPU) developed by simultaneously incorporating magnetically modified boron nitride nanosheets (M@BNNS) non-magnetic organo-grafted BNNS (U-BNNS) into waterborne polyurethane (WPU) synchronous molding under horizontal magnetic field. results indicate that continuous in-plane formed M@BNNS aligned along field direction, combined bridging structure established U-BNNS, enable Ho/U-BNNS/WPU exhibit exceptional ( λ // ) through-plane conductivities ⊥ ). In particular, addition of 30 wt% 5 composites reach 11.47 2.88 W m −1 K , respectively, which representing 194.2% improvement compared single orientation M@BNNS. Meanwhile, exhibits distinguished capabilities as interface LED chips. also demonstrate excellent flame retardancy, peak heat release total reduced 58.9% 36.9%, WPU. Thus, this work offers new insights thermally conductive structural flame-retardant systems polymer composites, presenting broad application potential packaging fields.
