“…In this way, to overcome the leakage problem of PCMs after melting, and help PCMs to store heat. The latest development of PCMs microencapsulation technology shows that the dual‐function or multifunction thermal energy storage materials can be realized by reasonably designing the composition and structure of shell materials 25 . In summary, if a high thermal conductivity material is added to the process of encapsulating PCMs with a functional inorganic material, microcapsules with anti‐leakage ability, high thermal conductivity, good thermal energy storage capacity, and special functions endowed by the shell material will be obtained.…”

Summary New multifunctional phase change microcapsules with paraffin (Pn) as core and GO and lead tungstate (PbWO4) as double‐shell were designed by modified GO Pickering emulsion, and the effect of GO content on Pn@GO@PbWO4 microcapsules was studied. The morphology, chemical composition, and structure of Pn@GO@PbWO4 microcapsules were characterized, and their performance was studied in depth. The Pn@GO@PbWO4 microcapsules had a dense shell and a regular spherical structure. Compared with microcapsules without GO addition, the resultant Pn@GO@PbWO4 microcapsules could demonstrate high phase change reliability and thermal stability. Most of all, the anti‐seepage performance had been greatly improved by 67.27%. The results of contact angle (CA) measurement and gamma‐ray shielding test showed that the GO and PbWO4 double‐shell multifunctional microcapsules with superhydrophobic property and good gamma‐ray shielding property and high anti‐seepage performance had great attraction in expanding the application field of phase change materials.

“…So far, a variety of leak-proof strategies have been developed, such as the use of encapsulated methods, the introduction of supporting material, especially porous scaffolds, and the fabrication of novel solid–solid composite PCM [ 109 ]. Sun et al [ 110 ] fabricated SiO 2 inner shell by interfacial polycondensation onto the n-diocesan core, and then coated with polyaniline/CNT as an electrochemically active layer to construct microcapsules with layer-by-layer shell structure ( Figure 7 a). The PCM microcapsules have the advantages of good shape stability, phase-change enthalpy up to 140 J/g and excellent working reliability, which are expected to become promising candidates for thermal management material of supercapacitors.…”

The boosting of consumer electronics and 5G technology cause the continuous increment of the power density of electronic devices and lead to inevitable overheating problems, which reduces the operation efficiency and shortens the service life of electronic devices. Therefore, it is the primary task and a prerequisite to explore innovative material for meeting the requirement of high heat dissipation performance. In comparison with traditional thermal management material (e.g., ceramics and metals), the polymer-based thermal management material exhibit excellent mechanical, electrical insulation, chemical resistance and processing properties, and therefore is considered to be the most promising candidate to solve the heat dissipation problem. In this review, we summarized the recent advances of two typical polymer-based thermal management material including thermal-conduction thermal management material and thermal-storage thermal management material. Furtherly, the structural design, processing strategies and typical applications for two polymer-based thermal management materials were discussed. Finally, we proposed the challenges and prospects of the polymer-based thermal management material. This work presents new perspectives to develop advanced processing approaches and construction high-performance polymer-based thermal management material.

“…27 Microencapsulation can not only reduce the leakage rate, but also reduce its flammability. 28 There were many reports about MEPCMs, which revealed that the shell of encapsulating PCMs contains organic and inorganic materials, including urea-formaldehyde (UF), 29,30 melamine-formaldehyde (MF), 31,32 polystyrene (PS), 33,34 silicon dioxide (SiO 2 ), 35,36 calcium carbonate (CaCO 3 ), 37,38 titanium dioxide (TiO 2 ), 39,40 and so on. MEPCMs are considered to be a more responsible method for solid-liquid PCMs, compared with the formation of form-stable PCMs.…”

A series of paraffin (Pa)@silicon dioxide (SiO 2 ) microcapsules with different core/shell ratios were constructed by interfacial-polycondensation of tetraethoxysilane (TEOS) and γ-Methacryloxypropyltrimethoxysilane (MPS), and then were embedded in addition-cure liquid silicone rubber (ALSR) to fabricate ALSR/Pa@SiO 2 phase-change composites. The SiO 2 shell can avoid the leakage of Pa. Meanwhile, the in-situ modification of the SiO 2 shell by MPS can enhance the interface bonding between Pa@SiO 2 and ALSR, because the C═C bond introduced by MPS on the SiO 2 shell can participate in the curing reaction of ALSR. The study explored the effects of the core/shell ratio on the Pa@SiO 2 microcapsules and ALSR/Pa@SiO 2 composites. Differential scanning calorimetry analysis demonstrated that ALSR/Pa@SiO 2 composites have dependable thermal energy storage capability which can reach to 90.7 J g À1 and phase-change enthalpy of the composites increase with the core/shell ratio. The ALSR/Pa@SiO 2 composites were found as form-stable phase-change materials with low leakage rate, which is attributed to the protection of both SiO 2 shell and ALSR matrix. Due to the chemical interfacial interaction, the composites displayed improved mechanical strength. The composites can be used for thermal management and temperature regulation as an electronic packaging material.
