Study on the Thermal Stability of Expanded Graphite/Stearic Acid Composite Phase Change Materials

摘要：

　　The expanded graphite/stearic acid composite phase change materials were prepared with stearic acid as phase change materials and expanded graphite as the carrier by the adsorption and encapsulation of expanded graphite.The thermal stability of composite phase change materials were analyzed by TG, XRD and SEM.Results showed that expanded graphite has reticular structure to encapsulate the stearic acid, improving its stability of thermal decomposition, thermal cycle and thermal chemical.When the content of expanded graphite is 10wt.%, the composite phase change materials exhibit good thermal stability, and can meet the requirements of temperature control under different conditions.
