硅藻土基复合相变储热材料研究现状

摘要

The earth is rich in diatomite resources. Such type of materials has a high porosity and favorable structural and thermophysical properties, and can therefore serve as the structural material for composite phase change materials. In this article, we first briefly introduces the structure and properties of diatomite, we then provide a state-of-the-art review on the use of the diatomite as the structural material for encapsulating phase change materials for thermal energy storage applications. Finally, further development in the area is discussed.%　　硅藻土是一种含量丰富的非金属矿，具有较高的孔隙率、良好的表面结构和热物理性能，因而可作为复合储热材料的载体。本文综述了复合储热材料的种类和制备工艺，并介绍了硅藻土的结构、性能和以硅藻土为载体的复合相变储热材料的研究及应用现状。
