The CNF/CH/PLR aerogel demonstrates a well-balanced porous structure with effective encapsulation of polyethylene glycol (PEG). Combining PLR with CNF/CH, the PEG leakage resistance was significantly improved. The resulting CNF/CH/20 %PLR-PEG composite exhibits exceptional enthalpy values of 181.1 J/g, along with superior mass retention rates under melting. These findings highlight the potential of this bio-based composite for advanced thermal energy storage systems, offering a sustainable and efficient solution for energy-efficient applications.4615225enghttp://creativecommons.org/licenses/by-nc-nd/4.0/Cellulose nanofiberPEGPolyrotaxanePorous materialsGeneral Materials ScienceCondensed Matter PhysicsMechanics of MaterialsMechanical EngineeringYesyesjournal articleopen access10.1016/j.matlet.2025.138623https://www.scopus.com/pages/publications/105003808219https://www.scopus.com/pages/publications/105003808219#tab=citedBy
