Research on the Preparation and Application of Composite Phase Change Heat Storage Materials

随着工业全球化程度的持续发展，能源消耗不断增加，能源生产与需求之间的差距越来越大。化石能源的不可再生性以及清洁能源的低利用率使人们越来越关注节能和高效能源的使用，因此储能技术的发展受到人们越来越多的重视。相变材料可以在相变过程中储存/释放能量，在建筑节能、工业废热余热利用和太阳能利用、电子元器件热保护等诸多领域都拥有广泛的应用前景。制备复合相变储热材料的方法主要有：熔融共混法、溶胶–凝胶法、静电纺丝法、原位聚合法、物理吸附法、超声波法、真空浸渍法等。With the continuous development of the degree of industrial globalization, energy consumption is increasing, and the gap between energy production and demand is widening. The non-renewability of fossil energy and the low utilization rate of clean energy make people pay more and more attention to the use of energy-saving and efficient energy, so the development of energy storage technology has been paid more and more attention. Phase change materials can store/release energy in the process of phase change, and have a wide range of application prospects in many fields such as building energy conservation, industrial waste heat utilization and solar energy utilization, and thermal protection of electronic components. The main methods for preparing composite phase change thermal storage materials are melt blending, sol-gel, electrospinning, in-situ polymerization, physical adsorption, ultrasonic, and vacuum impregnation.
