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.
