▎ 摘 要
Novel composite phase change materials (PCMs) based on three-dimensional reduced graphene oxide (3D-rGO) were fabricated. Both borax (Na(2)B(4)O(7)10H(2)O) and 3D-rGO were used to reduce the supercooling degree of sodium sulphate decahydrate. The T-history method was used in studying the effect of Na(2)B(4)O(7)10H(2)O and 3D-rGO on supercooling of PCM. It was found that both borax and 3D-rGO can reduce the supercooling degree of the composite PCMs, and the positive synergy effect between 3D-rGO and Na(2)B(4)O(7)10H(2)O is significant. These results provide valuable guidance for improving the phase transition properties of hydrated salts.
