“…Recently, MXene has attracted extensive attention of researchers due to its remarkable photoabsorption, electrical, and electromagnetic shielding properties . MXene nanosheets as well as porous MXene aerogels, were developed to be mixed with PCMs to improve encapsulation, thermal conductivity, and light/electric-to-thermal energy storage capacities of PCMs. − However, these MXene-based PCMs may show strong rigidity and low flexibility due to the easy friability of MXene scaffolds. , Flexible PCMs are an emerging type of materials that can exhibit shape variation function, thus exhibiting potential applications in thermal management with electronic devices. − Several methods including the chemical synthesis of intrinsically flexible PCMs and the physical encapsulation of PCMs into elastomers or elastic porous scaffolds are proposed to fabricate PCMs with balanced energy storage properties and device-level flexibility. − For example, Zou et al synthesized polyurethane/carbon nanotube (PU/CNT) composites with optimum latent heat and flexibility via tuning the molecular weight of poly(ethylene glycol), which served as light-driven thermal management materials for humans . Wu et al prepared olefin block copolymer/paraffin/expanded graphite (OBC/PW/EG) composites with enhanced thermal conductivity and flexibility, which could reduce the thermal contact resistance with batteries .…”

Multifunctional phase change materials (PCMs) are highly desirable for the thermal management of miniaturized and integrated electronic devices. However, the development of flexible PCMs possessing heat energy storage, shape memory, and adjustable electromagnetic interference (EMI) shielding properties under complex conditions remains a challenge. Herein, the multifunctional PCM composites were prepared by encapsulating poly(ethylene glycol) (PEG) into porous MXene/silver nanowire (AgNW) hybrid sponges by vacuum impregnation. Melamine foams (MFs) were chosen as a template to coat with MXene/AgNW (MA) to construct a continuous electrical/thermal conductive network. The MF@MA/PEG composites showed a high latent heat (141.3 J/g), high dimension retention ratio (96.8%), good electrical conductivity (75.3 S/m), and largely enhanced thermal conductivity (2.6 times of MF/PEG). Moreover, by triggering the phase change of the PEG, the sponges displayed a significant photoinduced shape memory function with a high shape fixation ratio (∼100%) and recovery ratio (∼100%). Interestingly, the EMI shielding effectiveness (SE) can be adjusted from 12.4 to 30.5 dB by a facile compression–recovery process based on shape memory properties. Furthermore, a finite element simulation was conducted to emphasize the advantage of the MF@MA/PEG composites in the thermal management of chips. Such flexible PCM composites with high latent heat storage, light-actuated shape memory, and adjustable EMI shielding functions exhibit great potential as smart thermal management materials in military and aerospace applications.

“…Flexible PCMs are defined as a component capable of withstanding a certain deformation (e.g., stretching, bending, and compression) and closely contacting with objects . Generally, high crystallinity that ensures the high energy storage capacity of PCMs is detrimental to the flexibility. − Considering the balance between flexibility and energy storage capacity, the strategies for preparing flexible PCMs can be divided into three categories: using porous supporting materials, , using encapsulation technologies, , and proper design of molecular structures. − The flexibility of PCMs prepared with porous supporting materials and encapsulation technologies comes from the flexible porous skeleton and the isolated crystal structure, respectively. Compared to them, the flexibility of PCMs by proper design of molecular structures comes from the elastic polymer molecular skeletons or the cross-linked polymer skeletons, which is expected to achieve large-scale production owing to their low cost and superior mechanical properties .…”

Phase change materials (PCMs) as one of the most potential latent heat storage techniques have been widely used for thermal management and energy storage. However, simultaneously imparting flexibility, high thermal conductivity, and considerable energy storage density to organic PCMs remains challenging. In this work, a coupling strategy combining substance exchange and magnetic orientation has been proposed to fabricate phase change gels (PCGs) with thermally induced flexibility and high through-plane thermal conductivity. In the PCGs, synthesized boron nitride/ferroferric oxide (BN@Fe3O4) particles and polyacrylic acid (PAA) precursor liquid are introduced to polyethylene glycol (PEG) aqueous solution, and a magnetic field is applied in the process of PAA network construction to promote ordered arrangement of BN@Fe3O4 along the direction of the magnetic field. Consequently, PEG is wrapped by the cross-linked PAA supporting network, forming PCGs with excellent shape stability and thermally induced flexibility. The vertical orientation structure of BN@Fe3O4 endows the PCGs with an enhanced through-plane thermal conductivity of up to 1.07 W m–1 K–1 at a BN@Fe3O4 loading of 25.6 wt % with an additional enhancement of 215% compared to the composite without BN. The thermally conductive leakage-proof PCGs present great application potential in heat storage and management.

“…Additionally, thermal barrier material should be applied to suppress battery TR after it occurs (Zhang et al, 2022). In general, the commonly used cooling methods in BTMS include air based, liquid based and phase change material (PCM) cooling (Saw et al, 2015;Wu et al, 2022). These cooling strategies have their advantages and disadvantages (Shen et al, 2021).…”
