“…This may be the result of the confinement effect of the BN particles on the mobility of SSD molecules in the melting processes . On the other hand, reaching high thermal conductivity and high phase change enthalpy of PCMs simultaneously is difficult . Since thermally conductive fillers and other polymer frameworks did not undergo a phase transformation within the working temperature range, only SSD accounts for the latent heat.…”

“…51 On the other hand, reaching high thermal conductivity and high phase change enthalpy of PCMs simultaneously is difficult. 52 Since thermally conductive fillers and other polymer frameworks did not undergo a phase transformation within the working temperature range, only SSD accounts for the latent heat. In general, when the mass fraction of the SSD is decreased, the latent heat is decreased.…”

Realizing the person thermal management (PTM) toward human body and its local environment is emerging as a research hotspot. Sodium sulfate decahydrate (SSD) possessing reversible thermal energy absorption, storage, and release around the human body temperature provides a promising solution for PTM and thermal comfort. However, developing SSD-based functional materials with superior thermophysical properties and wearability to enable efficient PTM still remains a huge challenge. Herein, a strategy of ionic cross-linking, chemical cross-linking, and boron nitride (BN) doping is developed to manufacture the high-performance hybrid SSD gels. The supercooling degree of the BN@SSD gels can be reduced to 0 °C. The thermal conductivity (1.2668 W m–1 K–1) of the BN@SSD gels can be increased by 63.14%. The BN@SSD gels present a large thermal energy storage capacity of 132.52 J g–1. The BN@SSD gels demonstrate excellent form stability to confine the liquid SSD and high cyclic stability of 200 cycles. Furthermore, The BN@SSD gels also possess superior wearability in terms of high flexibility, high self-repairing efficiency, and high cost effectiveness (5.53 × 10–3 ¥ g–1). Owing to the various merits of the synergistic enhancement effect, the BN@SSD gels are effectively utilized in wearable PTM to generate thermal comfort for the human body. The multifunctional thermal energy storage gels offer a promising route to the highly efficient application of PCMs in next-generation PTM.

“…However, it can be divided in four groups in the context of electricity generation 92 or, direct use in house-hold or, in industries such as (a) sub-zero PCMs such as salt-water mixtures with a congruent phase change temperature below 0 C, 93 ; (b) ice which has a phase change temperature to water of 0 C; (c) low-temperature PCMs with a phase change temperature of 0 C to 120 C such as paraffin waxes 94 and salt hydrates, 95 ; and (d) high-temperature PCMs with a phase change temperature above 120 C such as inorganic salts and their eutectic mixtures, including those stored in ceramic supporting materials known as composite PCMs. 96 The energy density of thermochemical storage is larger than that of sensible and latent heat storage. It can be divided into two categories (a) reversible reactionbased storage and (b) sorption-based energy storage.…”

“…23 Although various researchers have attempted the fabrication of functional PCM composites, the fabrication of advanced PCM material composites remains challenging. To reinforce the thermal properties of PCM for the thermal management of electric devices, highly thermal conductive fillers (graphene, 24 carbon nanotube, 25 carbon fiber (CF), 26 alumina, 27 aluminum nitride (AlN), 28 and boron nitride (BN) 29 ) are used. However, the high loading of fillers degrades the intrinsic latent heat of PCM.…”

In this study, an advanced phase change material (PCM) was fabricated to combine the properties of a biobased thermoplastic polymer and the heat storage of PCM to overcome the limitations of the existing PCM composites. The novel PCM of erythritol (ET)-grafted polylactic acid (PLA) (ETPLA) was prepared by the in situ polymerization of ET and PLA. The thermally conductive ETPLA composites were fabricated by injection molding using a hybrid filler system of oxidized carbon fiber (CF-OH) and aluminum nitride (AlN), which showed a high through-plane thermal conductivity of 4.25 W/mK, a tensile strength of 16.4 MPa (1953% enhancement comparing pure ET), an elongation at break of 4.4% (189% enhancement comparing pure ET), and latent heat of 170.7 J/g. Thus, the ETPLA/CF-OH/AlN composites facilitate efficient thermal management to combine heat saving and heat dissipation through the large latent heat and high thermal conductivity. Thus, the fabricated PCM composites have potential applications in thermal management systems of next-generation electronic devices.
