“…The double peaks at 2917 and 2849 cm −1 are expected to be due to the CH stretching and CH 2 /CH 3 groups of the alkyl chain of lauric acid 16 . A sharp peak at 1701 cm −1 is attributed to characteristic stretching of the C═O present in COOH 18,19 . Series of peaks noted at 1430, 1293, 937, and 724 cm −1 are attributed to the stretching/bending vibrations of OH, CH, C═O, and CO groups of lauric acid 20‐22 …”

The maintenance of incubation temperature (30 C-50 C) for growth of culture is essential during fermentation of milk to curd. This report discusses the issue of maintaining constant temperature of milk for formation of curd using lauric acid (m.p. 45.02 C and f.p. 40.21 C) as phase change material (PCM). Lauric acid possesses phase transition enthalpy, 189.43 kJ kg À1 and was thermally stable till 140 C. A known dimension of a temperature controlling packaging (TCP) box was made by taking 240 g of PCM uniformly distributed inside six polyethylene packets (40 g each) of dimensions identical with that of inner walls of the corrugated box and the packets were placed along inner walls of TCP box. The TCP box containing packets with molten PCM could maintain the temperature of 150 g milk (placed inside box) in between 50 C and 30 C for 160 minutes and helped in curd formation, while the whole assembly was exposed to 1 C of ambient temperature.

“…Shell material is the key to provide the stable encapsulation effect of the liquid PCM after solid–liquid phase transition, to ensure the cycle durability and no liquid leakage of PCM. Common functional coating material include polymers and inorganic material [ 114 ], such as polymethylmethacrylate (PMMA) [ 115 ], polystyrene (PS) [ 116 ], melamine formaldehyde (MF) [ 117 ], SiO 2 [ 118 , 119 ], titanium dioxide (TiO 2 ) [ 120 ], calcium carbonate (CaCO 3 ) [ 121 ], etc. Polymer has been widely used in functional coating material because of its advantages of good chemical stability, excellent processability, good mechanical properties, satisfactory compatibility with organic solid–liquid PCM.…”

The boosting of consumer electronics and 5G technology cause the continuous increment of the power density of electronic devices and lead to inevitable overheating problems, which reduces the operation efficiency and shortens the service life of electronic devices. Therefore, it is the primary task and a prerequisite to explore innovative material for meeting the requirement of high heat dissipation performance. In comparison with traditional thermal management material (e.g., ceramics and metals), the polymer-based thermal management material exhibit excellent mechanical, electrical insulation, chemical resistance and processing properties, and therefore is considered to be the most promising candidate to solve the heat dissipation problem. In this review, we summarized the recent advances of two typical polymer-based thermal management material including thermal-conduction thermal management material and thermal-storage thermal management material. Furtherly, the structural design, processing strategies and typical applications for two polymer-based thermal management materials were discussed. Finally, we proposed the challenges and prospects of the polymer-based thermal management material. This work presents new perspectives to develop advanced processing approaches and construction high-performance polymer-based thermal management material.

A series of microencapsulated phase change materials with an organic/inorganic composite shell was designed for obtaining excellent thermal compactness and thermal stability. The capsule wall was obtained via hydrolyzing ethyl orthosilicate with melamine resin as the hard template to MF/SiO2 materials for encapsulation n-octadecane. The results of chemical analysis and structure characterizations indicated that MF/SiO2 microcapsules with an obvious core–shell microstructure were successfully fabricated. The thermal conductivity of MF/SiO2 microcapsules is raised to 30.05% via comparing with original microcapsules. The microcapsules obtained present excellent latent heat storage and release properties (ΔH m = 167.1 J·g–1). The enthalpy value of the synthetic microcapsule hardly changed from 164.5 to 162.9 J·g–1 after extraction, indicating that the microcapsules have distinguished sealing performance. In addition, the MF/SiO2 microcapsules still presented noteworthy thermal cycle durability.
