Summary Dopamine‐functionalized mesoporous silica (DPMS), which was prepared by using a facile, easy to operate, and environmentally friendly biomimetic method, was synthesized as a new supporter of polyethylene glycol (PEG) to prepare shape‐stabilized phase‐change material (ss‐PCM) of PEG/DPMS with improved enthalpy. The thermal properties of PEG/DPMS were investigated, and the study results demonstrated that dopamine functionalization could regulate the crystallization property of PEG molecules immobilized in PEG/DPMS, and then the enthalpy of PEG/DPMS could be improved effectively. Compared with the ss‐PCM of PEG/SBA‐15 that was synthesized by using unfunctionalized silica molecular sieve (SBA‐15) as the matrix, after dopamine modification, the fusion and solidification enthalpies of 70‐wt% PEG/DPMS increased from 47.25 and 34.96 J/g to 69.77 and 67.54 J/g, respectively. The interaction mechanism study results suggested that the amino groups in the molecule of poly‐dopamines on the surface of DPMS could interact with the oxygen atoms in the molecules of PEG to form hydrogen bonds. Additionally, the PEG/DPMS had favorable thermal reliability and prominent thermal stability. Hence, the DPMS could be applied as a promising supporter for the fabrication of ss‐PCM.

“…1 A proper PCM for building applications should meet a number of criteria related to the desired thermophysical, kinetic, and chemical properties as well as economics. 4 Metal salts and hydrated salts are examples of inorganic PCMs while organic PCMs include paraffin and nonparaffin compounds. 2,3 They should also have a melting temperature slightly above 20°C to meet the need of thermal comfort of the building.…”

Summary The discovery of new eutectic phase change materials (PCMs) will overcome the current PCM challenges such as nonbiodegradability, super‐cooling, and limited thermal stability. This paper reports on the development of new bio‐based PCMs composed of binary mixtures of fatty acid esters and fatty alcohols at their eutectic compositions, which provide potential solid‐liquid PCMs for building applications. Six binary systems, namely 1‐dodecanol (DD) + methyl stearate (MES), DD + methyl palmitate (MEP), DD + methyl laurate (MEL), 1‐tetradecanol (TD) + MES, TD + MEP, and TD + MEL were prepared and their thermal behaviours were deliberated by differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), long‐term thermal stability test, and mass loss analysis. Amongst the studied systems, phase change transition temperature and latent heat of fusion of the eutectic mixtures of DD‐MES, DD‐MEP, TD‐MES, and TD‐MEP were found to be suitable for the building application with values of 22.46°C/201.91 J/g, 20.34°C/224.45 J/g, 32.05°C/209.38 J/g, and 26.72°C/210.15 J/g, respectively. The average degree of super‐cooling for all PCMs was below 2°C, and no significant changes in thermophysical properties of the developed PCMs were observed after 1000 thermal cycles.

“…Chai 7 studied the bifunctional microencapsulated n-eicosane for various applications, such as waste heat recovery and treatment, intelligent textiles and medical protective clothing, and food preservation. Abuelnuor 19 found that PCMs have great potentials to be used in modern building materials to stabilize indoor temperature fluctuations for improving thermal comfort. Sari 9 considered magnetic refrigeration a serious alternative system for food preservation.…”

Summary At present, all types of large–medium‐sized supermarkets with aquatic products adopt ice preservation to ensure freshness. The traditional method of ice preservation needs to make a large amount of thick ice and thus wastes manpower and freshwater. A new ice preservation system with cold storage (IP&CS) is designed, and its performance is tested. The use of a cold storage tank to replace the thick ice laid achieves a repeated cold storage and discharge. This experiment uses NaCl solution as the cold storage phase change material (PCM). The phase change temperature of the cold storage PCM and the optimum temperature of the secondary refrigerant during the cold storage process are determined. Results show that the center temperature of aquatic products, water loss rate, color of aquatic products, power consumption, and electricity cost of the IP&CS system are better than those of the traditional ice preservation system.
