Cover Picture: Since heat cannot be effectively introduced into phase change materials (PCMs), the thermal response rate is low. Besides, the heat storage and release speed is slow, which directly affects the energy storage efficiency and energy storage capacity of PCMs. Therefore, it is very important to select a suitable position and a compatible relationship between the thermally conductive material and the dispersed phase. This paper summarizes the relationship between GO and phase change microcapsules from four aspects: the types of PCMs, the combination method of GO and phase change microcapsules, the position and content of GO, and the application of PCM/GO microcapsules. The combination of capsules can be used to realize various micro-nanostructures for thermal energy storage. We studied and compared the effects of the position and content of GO in the microcapsule structure on the thermal properties of the capsule, such as latent heat and thermal conductivity. It is considered that adjusting and modifying the simultaneous distribution of GO in the capsule shell and core structure and constructing a three-dimensional thermal network are the ultimate solutions to improve the thermal conductivity of composite phase change microcapsules.
