Phase change materials (PCMs) store and release energy in the phase change processes. In recent years, PCMs have gained increasing attention due to their excellent properties such as high latent heat storage capacity, appropriate solid-liquid phase change temperature, thermal reliability, and low cost. Herein, classification, characteristics, and evaluation criteria of organic/composite PCMs are systematically illustrated, and some typical preparation methods are introduced, such as in-situ polymerization, interfacial polymerization, spray drying method, porous materials adsorption method, sol-gel method, meltimpregnated and mixing method, electrospinning method, vacuum infiltration and ultrasonic method are introduced. In addition, this review presents some applications of PCMs in the utilization of solar energy, building materials, air conditioning, industrial waste heat recovery, and military camouflage and stealth. Finally, the development tendency of PCMs is discussed.

“…3 Using high thermal conductive nanoparticles 4 can ameliorate this defect. 5 Qu et al 6 studied the effect of a hybrid of expanded graphite (EG) and multi-walled carbon nanotube (MWCNT) on the thermal conductivity enhancement of paraffin. The best result of their study was a 444% enhancement of the thermal conductivity for the hybrid nano-additives.…”

Polyethylene glycol (PEG) is limited by the low thermal‐conductivity and poor shape‐stability in practical applications. In our work, the thermal conductivity and shape‐stable phase change Materials (SSPCMs) doped with hydrothermal carbon (HTC) was successfully prepared. HTC with ‐ OH and ‐ COOH groups on the surface was prepared by hydrothermal carbonization of glucose. The hydrogen bonds were formed between functional groups on HTC surface and PEG to obtain the network structure. When the HTC doping ratio is 6 wt%, good shape‐stability can be achieved. Besides, the thermal conductivity of the HTC/PEG SSPCMs with the HTC doping ratio of 9 wt% is 0.6121 W/(m⋅K), which is 134.7% higher than PEG. The DSC results show that the melting enthalpy (ΔHm) of PEG and HTC/PEG SSPCMs is almost the same, as is the crystallization enthalpy (ΔHc). It indicates that doping HTC does not substantially affect the heat storage capacity of PEG.
