In this study, a form-stable composite phase-changing material (PCM) was synthesised by vacuum impregnation method. Natural Na-bentonite and lauric acid (LA) were used as the supporting PCM, respectively. addition, flake graphite (FG) for enhancing thermal conductivity of besides blocking leakage PCM. Notably, with addition FG, period melting freezing PCM decreased to certain extend. Meanwhile, heat-transfer characteristic increased. Moreover, as-prepared showed good reliability after 200 cycles thermal-cold treatment has potential be in energy storage systems.
