“…Phase change materials (PCMs) can reversibly store and release the thermal energy by the melting and crystallization of crystalline materials 11 , 12 , have attracted extensive attention for TES 13 systems in following fields: constructions and buildings 13 – 15 , solar energy storage 16 – 18 , geothermal energy storage 4 , battery thermal management system (BTMS) 12 , 19 and other thermal management system systems. Due to the high energy density, negligible temperature and volume variation of PCMs during the energy storage process, PCMs such as fatty alcohol 20 , polyethylene glycol 21 , paraffin 22 and fatty acid 23 have been extensive used in many fields like smart buildings, aerospace, smart cloths and industrial heat waste recovery etc.…”

To improve the homogeneity of phase-change materials (PCMs) composites for thermal energy storage, the poly(ethylene glycol monomethyl ether)-based trimethylolpropane (Ymer-N120) with long side ethyoxyl chains is employed to form comb-like polyurethane which functioned as supporting materials for PCMs. And the results of Fourier transform infrared spectroscopy (FTIR), X-ray diffraction, differential scanning calorimetry, accelerated thermal cycling testing, thermogravimetric analysis and field emission scanning electron microscopy (FESEM) suggested a crosslinked polyurethane embedded with micron grade myristic acid (MA) crystals was prepared during the thermal curing process. The obtained comb-like polyurethane (YP) can provide 3D structure supporting materials for melting MA. And the long side ethyoxyl chain of Ymer-N120 promote the melting MA form micron-sized crystals. The results of thermal reliability testing confirmed the advantages of same methylene groups in side chains and suggested the maximal hold capability of YP crosslinks is about 50 wt% of composites. With the 50 wt% addition of MA, YPM50 can supply high latent heat (over 90 J/g of YPM50) with fine thermal stability (due to its initial decomposing temperature reaches 190 °C) without leakage (after 500 times of accelerated thermal cycling testing). All results indicated this structure supplies an effective solution for the leakage of PCMs, which show a promising application in TES.

“…Therefore, the researchers used the binary combination method to obtain the composite PCMs with the required melting temperature, which has great application potential in architecture [25]. Organic composite PCMs are mainly prepared, for example, by paraffin and fatty acid [26], fatty acid and fatty acid [11,27,28], fatty acid and fatty alcohol [29][30][31][32]. Because fatty acids and fatty alcohols mainly come from the natural animal fat and vegetable oil, they have compared with paraffin lower flammability and better biodegradability [17,33].…”
