中文摘要：
以三水醋酸钠作为储能单元、环氧树脂为载体制得复合相变储能材料,它在熔点温度时表现出很强的稳定性和储能效果。通过向复合相变储能材料中添加导热率高的且具有多孔吸附性的膨胀石墨,可进一步提高导热性能和密封性能。结果表明,当三水醋酸钠质量分数为60%,膨胀石墨为5%时,相变储能材料相变焓为148.5 J/g,导热率为0.891 W/（m℃）,且稳定性良好。
英文摘要：
The new composites made of sodium acetate trihydrate（CH3COONa·3H2O） and ethoxyline resin（EP）,in a melting temperature are presented in terms of stability,storage capacity.Moreover,the addition of expanded graphite to enhance the thermal conductivity of the materials is presented in absorbability due to its porosity.The experiment results indicate new composites which contain sodium acetate trihydrate by 60wt% and expanded graphite by 5wt% possess thermal capacity of 148.5J/g and thermal conductivity of 0.89W/m℃,and presented well stability in the heating process.
