It is shown that paraffin can be uniformly absorbed into the pore network of expanded graphite , that expanded graphite remains its vermiform structure in pcms , that the phase - change temperatures of composite pcms are similar to that of paraffin , and that the latent heat of composite pcms is are based on the mass fraction of paraffin in the composite materials 结果表明：膨胀石墨吸附石蜡后仍然保持了原来疏松多孔的蠕虫状形态，石蜡被膨胀石墨微孔所吸附；复合相变储热材料的相变温度与石蜡相似，其相变潜热与基于复合材料中石蜡含量的潜热计算值相当。
