制备了纳米石墨/石蜡复合相变材料。NG具有提高复合材料导热性能的作用。采用环境扫描电镜和差示扫描量热法对材料的微观结构和热性能进行了研究。结果表明：纳米炭层在石蜡中呈随机分布，导热系数随纳米炭含量的增加而逐渐增大；含10% NG的材料导热系数为0.9362 W/m K. (C) 2013 Elsevier Ltd.。版权所有。
Nano-graphite (NG)/paraffin composites were prepared as composite phase change materials. NG has the function of improving the thermal conductivity of the composite. The microstructure and thermal properties of the materials were examined with environmental scanning electron microscopy and differential scanning calorimetry. The results indicated that the NG layers were randomly dispersed in the paraffin, and the thermal conductivity increased gradually with the content of NG. Thermal conductivity of the material containing 10% NG were 0.9362 W/m K. (C) 2013 Elsevier Ltd. All rights reserved.
