“…The thermal performance tests demonstrated that the temperature-adjusting asphalt pavements included PCM/diatomite composite can reduce the peak temperature of the upper and bottom surface by up to 8.11 • C and 6.36 • C during a representative summer day. Abden et al prepared methyl stearate/diatomite composite (with the melting temperature of 36.5 • C and LHS of 111.8 J/g) and embedded it into the foamed gypsum board [92]. The gypsum board contained about 40 wt% of the composite particles.…”

The development of novel materials and approaches for effective energy consumption and the employment of renewable energy sources is one of the current trends in modern material science. With this respect, the number of researches is focused on the effective harvesting and storage of solar energy for various applications. Phase change materials (PCMs) are known to be able to store thermal energy of the sunlight due to adsorption and release of latent heat through reversible phase transitions. Therefore, PCMs are promising as functional additives to construction materials and paints for advanced thermoregulation in building and industry. However, bare PCMs have limited practical applications. Organic PCMs like paraffins suffer from material leakage when undergoing in a liquid state while inorganic ones like salt hydrates lack long-term stability after multiple phase transitions. To avoid this, the loading of PCMs in porous matrices are intensively studied along with the thermal properties of the resulted composites. The loading of PCMs in microcontainers of natural porous or layered clay materials appears as a simple and cost-effective method of encapsulation significantly improving the shape and cyclic stability of PCMs. Additionally, the inclusion of functional clay containers into construction materials allows for improving their mechanical and flame-retardant properties. This article summarizes the recent progress in the preparation of composites based on PCM-loaded clay microcontainers along with their future perspectives as functional additives in thermo-regulating materials.

“…1,2 Organic phase-change materials (PCMs) used as LHS devices are an exceptionally promising approach to alleviate these aforementioned concerns by providing reversibly high thermal energy storage (TES) capacities with isothermal operating characteristics during the phase transition process. [3][4][5][6] Recently, organic PCMs, such as paraffin wax, [7][8][9] fatty alcohols, [10][11][12][13] fatty acids, [14][15][16] fatty amines, [17][18][19] and polyethylene glycol, 20,21 have been extensively employed as TES and thermal management systems (TMS) for energy-saving buildings, [22][23][24][25][26] electronic devices, 27,28 lithium-ion batteries, [29][30][31][32] solar energy harvesting plants, 33,34 waste heat recovery, 35 and smart thermos-regulated textiles 36 according to their various merits, such as high Dongli Fan and Yuan Meng contributed equally to this work.…”

Form‐stable phase‐change materials supported by 1‐octadecylamine‐modified montmorillonite for latent heat storage

Form-stable phase-change materials (FSPCMs) are of great significance for relieving the contradiction of energy supply and demand. Unfortunately, the practical application of FSPCMs is severely compromised by their intrinsic drawbacks including lower latent heat storage (LHS) capacities, inferior interfacial compatibility, and cycling durability. Herein, we have provided a group of novel FSPCMs with higher LHS capacities, using paraffin as the LHS materials, which tightly intertwines with the 1-octadecylamine-modified montmorillonite (C18-MMT) under the capillary action as well as induced dipole force due to its n-alkyl chains compatibility. The obtained composite FSPCMs not only exhibit high melting enthalpies (137.56 J/g) but also demonstrate enhanced shape stability and thermal stability. In addition, the composites also render an impressive long-term thermal cycling capability and structure stability even after 100 thermal cycling durability tests, which are believed to have great potential for application in the thermal management of green energysaving buildings.

“…Compared with microencapsulation, the formstable method is simpler and more economic because this method can effectively achieve large-scale production. [27][28][29][30] Abden et al developed form-stable PCM by incorporating PCM into diatomite, which was then integrated into the gypsum board ceiling for building energy conservation. [31] The energy-saving performance and economic feasibility of the composites board were confirmed by the experimental results evaluated in a small-scale test chamber.…”

Phase change material (PCM) can store heat at a constant temperature, which is beneficial to reduce building energy consumption. Herein, we fabricated a PCM board that can store 98-102 J/g heat at 26 °C. The PCM boards were paved as the floor in the real-scale office to reduce power for temperature regulation, which led to the reduced energy consumption of 18.8% and 19.7% in winter and summer, respectively. A numerical model is validated by experimental data to evaluate longterm performance. The experiment and simulation results both demonstrate the high-performance PCM floor for effective reduction in electricity consumption of heating and cooling.
