“…Phase change materials (PCMs) have been applied in various fields for decades, for example, textile, building, construction, electronics solar energy storage, food storage and so on [1–10] . The working principle of PCMs is that temperature of PCMs can fluctuate over a certain temperature range while thermal energy can be stored or released according to difference between temperature of PCMs and environment temperature [11–13] . The organic PCMs are generally used due to several advantages (e. g., non‐corrosion, non‐toxicity, high thermal stability, high chemical stability etc.)…”

Structural Analysis of Phase Change Materials (PCMs)/Expanded Graphite (EG) Composites and Their Thermal Behavior under Hot and Humid Conditions

Expanded graphite (EG) has been used to store phase change materials (PCM) to enhance thermal conductivity and avoid leakage. However, systematic investigation on physical structure of various embedded PCMs in EG is not reported. Besides, the effect of environment on thermal behavior of PCM/EG composites has not been investigated yet. In this work, three common PCMs (including myristic acid (MA), polyethylene glycol (PEG) and paraffin wax (PW)) were embedded in EG and three PCM/EG composites were obtained. As a result, capillary force between EG and PCMs supported encapsulation of PCMs in EG. PCM/EG composites had narrower phase change range while supercooling degree values were different when various PCMs were used. Besides, the hot and humid environment had a side effect on thermal energy storage of PCMs and PCM/EG composites. The inherent hydrophilicity of PCMs was essential for resistance against side effect of moisture on thermal energy storage.

Polyurethane phase change microcapsules (PU‐PCMs) with high encapsulation efficiency are fabricated with ethyl palmitate as the phase change material and fatty acid monoglyceride based waterborne polyurethane as the shell. The compositions and morphologies of microcapsules are characterized by Fourier transform infrared spectrometer (FT‐IR), field scanning electron microscope (FSEM) and laser particle size analyzer. The encapsulation efficiency and phase change performances of microcapsules are investigated by thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC). The results show that PU‐PCMs have smooth surface and spherical shape and the size of about 300 nm. TGA and DSC results show that the encapsulation efficiency of ethyl palmitate in PU‐PCMs prepared with fatty acid monoglyceride is up to 92.3%, which is much higher than that of PU‐PCMs prepared with other diols. The fatty acid monoglyceride based polyurethane prepolymer has better affinity with ethyl palmite than polyurethane prepolymer prepared with other diols, which causes the high encapsulation efficiency of phase change materials. The result of DSC show that the melting enthalpy of fatty acid monoglyceride based PU‐PCMs is 81.6 J g−1 and the phase change temperature is 26.75°C. After 200 heating/cooling cycle test, the phase change temperatures and shapes of microcapsules remain unchanged, which show that the microcapsules have good phase change stability. The temperature‐regulating performance and application of the PU‐PCMs in fabricating semi‐transparent temperature‐regulating glass are conducted and investigated. Results of these investigations indicate that PU‐PCMs fabricated from fatty acid monoglyceride show promising applications in heat‐energy storage and temperature‐regulation fields.

“…With the rapid development of human society, people’s demand for energy is increasing. Therefore, solving the imbalance between energy supply and demand and improving energy utilization efficiency have attracted wide attention from researchers. , As one class of advanced energy storage materials, phase change materials (PCMs) can store and release a large amount of latent heat to realize the controllable storage and release of thermal energy, which can improve the high efficiency of energy utilization and can be used in various application areas of life. − In particular, most commercial microelectronic devices accelerate aging at high temperatures, seriously affecting the overall life of electronic equipment.

Phase change materials (PCMs) that can effectively improve the efficiency of energy storage and conversion have been used in the field of microelectronic devices for prolonging service life. However, conventional PCMs are easy to cause brittle fractures and damage to microelectronic devices because of their strong rigidity, which cannot perfectly fit the irregular surface of microelectronic devices. Herein, we successfully synthesized a dynamic covalently cross-linked shape memory PCM (HPCM8K) with polyethylene glycol (PEG) as the phase change component, hexamethylene diisocyanate trimer as the crosslinking point, and a disulfide bond as the dynamic covalent bond. The tensile strength and the elongation at break of the designed HPCM8K-1 can reach 27.7 MPa and 853.1%, respectively; meanwhile, HPCM8K has excellent latent heat storage capacity with the highest latent heat of 98.1 J/g. Importantly, these HPCM8K can integrate both traditional elastic shape memory and permanent shape reconstruction capabilities into one PEG-based dynamic cross-linking network after introducing the disulfide bond in the molecular structure. The key point of this work is to introduce exceptional mechanical performance and remarkable shape memory ability into PCMs, greatly improving the operability of shape change and enhancing their shape adaptability for accommodating different surfaces of microelectronic devices.
