Recent advances in thermosetting resin-based composite phase change materials and enhanced phase change energy storage

Thermosetting resin is a kind of resin material that can be cured by cross-linking reaction under the condition of heating or radiation, and gradually hardened and molded, which has the advantages of high heat resistance and not easily deformed by pressure, and it was widely used in the fields of coating, adhesive and electronic packaging. Existing studies have shown that the problem of leakage during phase change energy storage of solid-liquid phase change materials can be effectively solved due to the curing and molding of thermosetting resin by heat. This paper presents the first review of the current research status of thermosetting resins in the field of phase change energy storage from the classification of thermosetting resins, including: (1) Research progress of stereotyped phase change materials based on phenolic resin encapsulation; (2) Research progress of stereotyped phase change materials based on epoxy resin encapsulation; (3) Possibilities of dicyclopentadiene petroleum resin for phase change energy storage applications. At the same time, the future research focus and development trend of thermoset resin-reinforced phase change energy storage materials are prospected from the perspectives of modification at preparation and disposal and recycling at disposal, aiming to provide useful references for broadening the application scope of thermoset resin in the field of phase change energy storage and to provide more research ideas for the preparation of stereotyped phase change materials with excellent performance. © 2023 Beijing University of Aeronautics and Astronautics (BUAA).
