Diels-Alder (DA) chemistry is becoming increasing popular due to its simplicity and efficiency; however, one concept that has yet to be thoroughly explored is the incorporation of DA linkages to prepare polymeric phase change materials. It is well established that the retro-DA reaction results in a large endotherm, which could be a potential energy sink for thermally-sensitive materials. Furthermore, by crosslinking polymeric materials via DA linkages, upon the application of a thermal stimulus the network gel would be cleaved to individual polymer chains resulting in phase change analogous to a solid-liquid phase change. A variety of DA linkage systems were developed and incorporated in a variety of matrix materials.
