“…The thermal conductivity of mesoporous carbon (MC) is better than that of MS, and has the good thermal stability and uniform pore size, which has also been widely studied in SSPCMs. Feng et al 138 prepared a PEG/MC composite with the melt impregnation method, and it was found that the maximum load ratio of this SSPCMs can reach 75 wt.%. Besides, the thermal conductivity of the prepared SSPCMs is 60% higher than that of pure PEG.…”

Phase change materials (PCMs) are usually used in latent thermal energy storage systems to address the mismatch between heat energy supply and demand, due to their high energy storage density, high-latent heat, and almost constant temperature during phase change process. However, the low-thermal conductivity of PCMs and severe leakage during phase change limit their practical applications. Thus, extensive efforts have been devoted to constructing shapestabilized PCMs (SSPCMs). In this review, recent advances of the construction strategies and thermal energy storage applications of SSPCMs are summarized. Especially, the microencapsulated PCMs, SSPCMs based on porous scaffolds, as well as their potential applications are highlighted. Finally, the future perspectives and remaining challenges in this research field are prospected.

“…Therefore, to reduce the deformation of PCMs and improve their shape stability, the PCM matrix needs to be confined in a certain space. At present, the methods to improve the shape stability of PCMs mainly include the spherical microcapsule method, hollow tube microcapsule method, , nanomaterial adsorption method, , complexation cross-linking network method, chemical cross-linking network method, silica network confinement method, , metal network confinement method, , carbon network confinement method, polymer network confinement method, and so on.…”

The low thermal conductivity and poor shape stability of phase change materials (PCMs) have seriously restricted their applications in energy storage and energy saving. In this paper, poly(ethylene glycol)–calcium chloride/carbon/carbon fiber felt (PEG-CaCl2/CCF) PCMs were fabricated by a liquid-phase impregnation–vacuum drying–hot compression molding method with carbon/carbon fiber felt as the three-dimensional (3D) thermal skeleton and PEG-CaCl2 as the polymer PCM matrix. PCMs were heated and compressed by the compression confinement method to improve the contact area between 3D skeleton carbon fibers. The carbon fibers in PCMs presented a 3D (X–Y–Z) network structure and the fiber arrangement was anisotropic, which were beneficial to improve the thermal conductivity of PCMs in the fiber direction. The compression confinement can improve the contact area between the fibers in the 3D skeleton. As a result, the thermal conductivity of PEG-CaCl2/CCF PCMs can reach 3.35 W/(m K) (in-plane) and 1.94 W/(m K) (through-plane), about 985 and 571% of that of PEG-CaCl2, respectively. Due to the complexation of PEG and CaCl2 and the 3D skeleton support of carbon fiber felt, PCMs have excellent shape stability. The paper may provide some suggestions for the preparation of high thermal conductivity and excellent shape stability PCMs.
