中文摘要：

石蜡类有机物用做相变储能材料具有相变焓高、相变温度范围广、价格低等优点，但其较低的导热系数限制了吸／放能效率的提升。添加高导热物质合成复合相变材料，用以强化石蜡类有机相变材料传热能力是非常有前景的研究方向。评述了多种石蜡基复合相变材料的合成方法及热学性能，并展望了石蜡基复合相变材料的发展趋势。

英文摘要：

Due to the high storage density, the large range of phase change temperature and the low price, paraffin waxes have been applied as phase change materials （PCMs）. In spite of their desirable properties of the original materials, low thermal conductivities are their major drawback. The low thermal conductivities in turn limit their utility areas. To overcome the low thermal conductivity problem, solid particles with high thermal conductivity were added into the melting paraffin wax to make nanocomposite. The authors summarize the merits and defects of the paraffin wax based composite phase change materials and prospected the development trend of the paraffin wax based composite PCMs.
