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.
