摘要: 有机相变材料(PCMs)的导热系数小、储热放热速率低,在一定程度上限制了它的实际应用。以碳材料为吸附载体或填料的形式与有机相变材料进行复合,利用其优异的导热性能来提高有机相变材料的导热系数,已成为储热技术的研究热点。本文介绍了几种碳材料的特点,重点综述了国内外在利用多孔碳材料、碳纤维以及碳纳米材料改善有机相变储能材料导热性能方面的研究现状。指出多孔碳材料既能改善有机相变材料的导热性能,又能对相变材料起到封装作用,具有广阔应用前景,提出新兴碳纳米材料在相变导热强化方面具有巨大优势,纳米复合相变材料在未来仍是研究热点,应加大研究力度。

Abstract: Low thermal conductivity is one of the primary disadvantages of organic based phase change materials, which is the main reason behind the slow charging/discharging kinetics and restricts the practical applications of this type of materials. Recent research has shown an increased interest in the use of carbon materials, which not only have a high thermal conductivity, but also can be used as an adsorption carrier or a filler of organic PCMs. In this paper, we shall review the characteristics of carbon materials particularly microporous carbon, carbon fibers and carbon nanomaterials, and the use of these materials for the enhancement of thermal conductivity of organic based PCMs. We shall show that microporous carbon materials not only can enhance the thermal conductivity of organic PCMs, but also act as an encapsulation matrix for organic PCMs. Carbon nanomaterials appear to have great advantages in terms of thermal conductivity enhancement and nano-enhanced phase change processes, but this aspect is still in the early stage and requires extensive future research.

Key words: organic phase change materials, carbon materials, thermal conductivity, nano-enhanced phase change materials
