“…12–17 In line with this trend, Chen et al prepared a series of SiO 2 -based SSPCMs through physical blending and chemical modification, and subsequently produced phase change fibers with excellent mechanical properties and temperature-regulating capabilities using melt spinning technology. 18 Nevertheless, such scaffold lacking inherent phase change attributes and its structural constraints on the crystallinity of phase-change components resulted in a substantial reduction in the enthalpy of the composite PCMs, notably undermining their thermal management efficacy. 19–21 To tackle this, Zhang et al initially introduced a method where toluene-2,4-diisocyanate and triphenylmethane triisocyanate react with PEG10000, resulting in linear polyurethane and 3D network support materials exhibiting phase change properties.…”

Phase‐change textiles can achieve temperature regulation in variable ambient environments, however, augmenting the amounts of phase‐change materials (PCMs) in textiles remains a significant challenge due to the occurrence of leakage with higher amounts. Herein, a novel approach is proposed for the fabrication of a hierarchical nanofiber textile embedded with a substantial quantity of phase‐change microcapsules (PCMC) using electrospinning. Such nanofiber textile is composed of a polyvinylidene fluoride‐hexafluoropropylene fibers (PVDF‐HFP) layer and a polyvinyl butyral fibers doped with 60 wt% of PCMC (PVB/PCMC‐60) layer. Gratifyingly, doped PCMC shows no signs of rupture and exhibits excellent cycling stability. Furthermore, the incorporation of the PCMC does not affect the spectral characteristics of the PVDF‐HFP layer while providing a substantial enthalpy of fusion (92.6 J g−1) to the PVB/PCMC‐60 layer. This serves to compensate for the deficiency in radiative cooling capacity and effectively mitigates temperature fluctuations and overheating of the textile. Outdoor test results indicate that the nanofiber textile can achieve temperature drops of 3.7 and 14.8 °C compared to textile without the PCMC (namely PVDF‐HFP/PVB) and cotton, and attains a subambient temperature drop of 6.5 °C. Additionally, the nanofiber textile exhibits desirable mechanical strength, flexibility, washability, breathability, moisture permeability, and sun protection.

Passive battery thermal management systems (BTMSs) are critical for mitigation of battery thermal runaway (TR). Phase change materials (PCMs) have shown promise for mitigating transient thermal challenges. Fluid leakage and low effective thermal conductivity limit PCM adoption. Furthermore, the thermal capacitance of PCMs diminishes as their latent load is exhausted, creating an unsustainable cooling effect that is transitory. Here, an expanded graphite/PCM/graphene composite that solves these challenges is proposed. The expanded graphite/PCM phase change composite eliminates leakage and increases effective thermal conductivity while the graphene coating enables radiative cooling for PCM regeneration. The composite demonstrates excellent thermal performance in a real BTMS and shows a 26% decrease in temperature when compared to conventional BTMS materials. The composite exhibits thermal control performance comparable with active cooling, resulting in reduced cost and increased simplicity. In addition to BTMSs, this material is anticipated to have application in a plethora of engineered systems requiring stringent thermal management.
