摘　　要：相变微胶囊有效解决了相变材料在使用时产生的相分离、泄漏、腐蚀等问题。传统相变微胶囊往往缺乏光吸收能力,对太阳能利用率低,而将光热材料与相变微胶囊复合不仅能提高微胶囊对光的吸收作用,赋予相变微胶囊光热转换能力,还能增强其对相变材料的封装作用。首先对不同种类的光热材料进行介绍,并分析其光热转换原理。之后对光热材料用于制备光热相变微胶囊进行分析,重点介绍当前光热转换相变微胶囊的种类及光热材料对相变微胶囊性能的影响。最后对光热转换相变微胶囊存在的问题进行分析,并指出需要简化光热转换相变微胶囊的制备工艺,提高光热转换效率,推进其在太阳能利用领域的实际应用。Phase change microcapsules effectively solve the problems of phase separation, leakage, and corrosion that occur when phase change materials are used. However, traditional phase-change microcapsules often lack light absorption ability and have low utilization of solar energy, whereas by compositing photothermal materials with phase-change microcapsules not only improves the absorption of light and endows phase-change microcapsules with photothermal conversion ability, but also enhances the encapsulation of phase-change materials. Firstly, different kinds of photothermal materials are introduced and the principle of photothermal conversion is analyzed. Afterwards, the use of photothermal materials for the preparation of photothermal phase change microcapsules is analyzed, focusing on the current types of phase change microcapsules for photothermal conversion and the influence of photothermal materials on the performance of phase change microcapsules. Finally, an analysis is conducted on the problems of phase change microcapsules for photothermal conversion, and it is pointed out that it is necessary to simplify the preparation process of phase change microcapsules for photothermal conversion, improve the efficiency of photothermal conversion, and promote their practical application in the field of solar energy utilization.
