“…The results underline the potential use of PCM to control heat exchange within commercial insoles and the use of epoxy resins as a material to control heat exchange [ 27 , 28 , 29 ]. There are few references to PCM in the context of footwear [ 30 , 31 ] in which different materials are employed for heat control.…”

Thermal comfort is essential when wearing a postural-corrective garment. Discomfort of any kind may deter regular use and prolong user recovery time. The objective of this work is therefore to optimize a new compound that can alter the temperature of orthopedic insoles, thereby improving the thermal comfort for the user. Its novelty is a resin composite that contains a thermoregulatory Phase-Change Material (PCM). An experimental design was used to optimize the proportions of PCM, epoxy resin, and thickener in the composite and its effects. A Box–Behnken factor design was applied to each compound to establish the optimal proportions of all three substances. The dependent variables were the Shore A and D hardness tests and thermogravimetric heat-exchange measurements. As was foreseeable, the influence of the PCM on the thermal absorption levels of the compound was quantifiable and could be determined from the results of the factor design. Likewise, compound hardness was determined by resin type and resin-PCM interactions, so the quantity of PCM also had some influence on the mechanical properties of the composite. Both the durability and the flexibility of the final product complied with current standards for orthopedic insoles.

“…These core-shell capsules typically have PCM loadings near 50%-60% [38], but higher PCM loadings, up to 80%, has also been reported [35]. However, the overall loading capacity can be further reduced when these PCM-containing capsules are incorporated into bulk supporting materials such as foams, films, and fibers [39][40][41][42].…”

Electrospinning is a straightforward technique for the fabrication of nanofibers with the potential for various applications. Thermal energy storage systems using electrospun nanofibers have gained researchers’ attention due to its desirable properties such as nanoscale diameter, large surface area, excellent thermal conductivity, and high loading and thermal energy storage capacity. The encapsulation of phase change materials (PCMs) in electrospun nanofibers for storing renewable thermal energy can be achieved by uniaxial electrospinning of a blend of PCM and polymer, coaxial electrospinning of a PCM core and a polymer sheath, or post-electrospinning absorption. The PCM content and thermal energy storage capacity of different PCM composite nanofibers are compared in this chapter. The drawbacks of traditional electrospinning PCM encapsulation techniques and benefits of post-electrospinning encapsulation methods are discussed.

“…However, PA as an organic solid–liquid PCM has the defects of leakage and low thermal conductivity which restrict its utilization in battery packs. To address these problems, there are some researchers endeavored to explore the assembly of polymers with PA, for example, epoxy resin (ER), low-density polyethylene (LDPE), high-density polyethylene (HDPE), and linear low-density polyethylene (LLDPE) . Nevertheless, these composite PCMs (CPCMs) with skeleton materials can cause fracture with external forces, which will bring about the leakage of CPCM.…”

Battery thermal management systems (BTMSs) with composite phase-change materials (CPCMs) have attracted much attention owing to their improved temperature consistence in battery packs, but they still have obvious challenges such as easy leakage and low thermal conductivity. Herein, paraffin (PA)/styrene–butadiene–styrene (SBS)/thermoplastic polyurethane (TPU)/expanded graphite (EG) (PSTE) has been successfully prepared and utilized in battery modules. PSTE exhibits high antileakage under 70 °C high-temperature condition, which can maintain the quality maintenance rate to more than 99.9% compared with other samples. It is attributed that TPU as the interpenetrating layer can mingle with SBS uniformly, which will play a synergistic effect to restrict the leakage of CPCM. Besides, the thermal conductivity values of PSTE with various mass fractions of EG between the axial and radial directions after compression are compared. It reveals that the thermal conductivity of PSTE with 4 wt % EG is much higher than that of pure PA in the radial direction after compression. Meanwhile, the mechanism of EG with anisotropy is explained in detail. Further, the temperature consistence of the battery module with PSTE4 is markedly higher than other two modules, and the maximum temperature and temperature difference can be controlled below 44.7 and 3.6 °C, respectively, which indicates that PSTE4 can promptly dissipate the heat generated with batteries. Therefore, the designed CPCM with a highly efficient antileakage and thermally conductive composite material will provide versatile thermal management systems in practical applications.
