Integrating MXene Film With Recyclable Polyethylene Glycol‐co‐Polyphosphazene Copolymer as Solid–Solid Phase Change Material for Versatile Applications

Phase-change materials (PCMs) stand a pivotal advancement in thermal energy storage and management due to their reversible phase transitions to store and release an abundance of heat energy. However, conventional solid-liquid PCMs suffer from fluidity and leakage in their molten state, limiting their applications at advanced levels. Herein, a novel Zn
