“…As shown in Figure , the PCM microcapsules had almost smooth, compact, and spherical appearances, and their particle sizes ranged from 0.60 to 1.1 μm. The appearances of the microcapsules were in accordance with the literature . According to PSD analysis, the mean diameter of the obtained microcapsules was 0.840 ± 0.11 μm and had a unimodal distribution.…”

“…Among these materials, aliphatic hydrocarbons produced by petrochemical processes, called paraffins , are very popular because of their many advantages, including their high‐energy storage densities and low vapor pressure. Moreover, their reasonable price, mixability with other organic PCMs, and attractive properties, including their noncorrosivity, nontoxicity, nonreactivity, and chemical and thermal stability, make them a desirable material for many thermal storage applications . However, leakage problems during the melting–solidifying period are a disadvantage for paraffins.…”

A series of microencapsulated phase‐change materials (PCMs) with styrene–divinyl benzene shells composed of an n‐octadecane (OD or C18)–n‐hexadecane (HD or C16) mixture as the core were synthesized by an emulsion polymerization method. The effects of the core/shell ratio (C/S) and surfactant concentration (Csurf) on the thermal properties and encapsulation ratios of the PCMs were investigated. The chemical structures and morphological properties of the microcapsules were characterized by Fourier transform infrared (FTIR) spectroscopy and scanning electron microscopy analysis, respectively. The characteristic peaks of the paraffin mixtures and shell material located in the FTIR spectrum of the microencapsulated PCMs proved that the encapsulation of the PCM mixture was performed successfully. The thermal properties of the paraffin microcapsules were determined by differential scanning calorimetry (DSC) and thermogravimetric analysis. DSC analysis demonstrated that the microcapsules containing the maximum amount of paraffin mixture (C/S = 2:1) and the minimum Csurf (45 mmol/L) had the highest latent heat value of 88 kJ/kg and a latent heat of temperature of 21.06°C. Moreover, the maximum encapsulation ratio of the paraffin mixture was found to be 56.77%. With respect to the analysis results, the encapsulated binary mixture, which consisted of OD–HD with a poly(styrene‐co‐divinyl benzene) shell, is a promising material for thermal energy storage applications operating at low temperatures, such as in the thermal control of indoor temperatures and air‐conditioning applications in buildings for desirable thermal comfort and energy conservation. © 2019 Wiley Periodicals, Inc.

This article introduces a facile approach for applying a eutectic mixture of fatty acid phase-change materials (PCMs) on polyester fibers for thermal conductivity improvement via the in situ incorporation of copper nanoparticles. For this purpose, a eutectic mixture of palmitic acid and lauric acid was applied as PCMs and ascorbic acid was applied for the synthesis of copper nanoparticles. The thermal properties and stability of the treated samples were also determined by differential scanning calorimetry and thermogravimetry analysis. The treated samples indicated appropriate phase-transition temperatures between 29.1 and 36.8 C, with relevant latent heats of 49.4 and 49.9 J/g, respectively. The in situ formation of copper nanoparticles into eutectic fatty acid applied on the polyester fibers resulted in the promotion of the thermal conductivity of the composite by about 100.1% with the maximum amount of nanoparticles. In addition, the treated samples maintained good thermal durability and stability after 100 melting and freezing cycles. In addition, the tensile strength of the treated samples was improved. Overall, this treatment could be used to produce promising form-stabilized composite PCMs and thermoregulated polymers and textiles with appropriate phase-transition ranges and thermal conductivity.
