摘要：

With composite glauber's salt (SCNa) as phase change materials, expanded graphite as the carrier, a highly thermal conductive expanded graphite/Na2SO4·10H2O composite phase change energy storage material (EG/SCNa) was prepared by vacuum adsorption method. Experimental results showed that surfactant OP-10 (weigh content 5%) could effectively improve the combination stability of expanded graphite and Na2SO4·10H2O composite phase change material. There was no difference in shape-stabilized phase change materials whether surface active agent added or not. The thermal conductivity of shape-stabilized phase change materials added with surface active agent was 2.26 W/(m·K), 115% higher than that of the original composite glauber's salt phase change material. © 2016, Materials Review Magazine.
