Continuous Dual-Scale Interpenetrating Network Carbon Foam-Stearic Acid Composite as a Shape-Stabilized Phase Change Material with a Desirable Synergistic Effect.

For enhancing the heat storage and encapsulation performances of organic phase change materials (PCMs), a carbon foam (CF) with a continuous dual-scale pore structure (DCF) was developed. Employing the as-prepared DCF as a stearic acid (SA) support, a novel shape-stabilized SA-CF composite PCM with a continuous dual-scale interpenetrating network structure was achieved through the impregnation of SA into the DCF. DCF-900, prepared at an activation temperature of 900 °C, possesses a high loading capacity of 89.
