Thermal properties of graphite/salt hydrate phase change material stabilized by nanofibrillated cellulose

Thermal energy storage (TES) systems using phase change materials (PCMs) are of increasing interest for more efficient energy utilization. Herein, sodium sulfate decahydrate (Na2SO4·10H2O; SSD)/nanofibrillated cellulose (NFC)/graphite PCM composites were prepared by a simple blending method. NFC and graphite were used to improve the performance of SSD-based PCMs by mitigating the phase separation and low thermal conductivity issues. The phase...
