“…As described in the time–temperature curve in Figure S2 , the temperature of PEG was always higher than 8CPP before 4000 s; between 4000 s and 5000 s, 8CPP gradually exceeded PEG and increased slightly; then, the temperature of PEG dropped to the initial temperature at 5670 s, and 8CPP was still close to 18 °C at this time. When PEG was the same as the ambient temperature, 8CPP still maintained a certain amount of heat, which fully reflects that 8CPP has good heat storage performance, indicating that the prepared composite can adjust the ambient temperature [ 32 ]. In Figure 6 b,c, the pure PEG displayed a melting temperature ( T m ) of 17.32 °C, and the composite phase change material melting temperature had a range of 17.91 °C–21.19 °C, so it is believed that the rise in the phase-transition point in the composite can be considered as the confinement of PEG in the composites.…”

The research on the high-value utilization of biomass has good application prospects and is conducive to sustainable development. In this paper, three different types of activators (potassium hydroxide, phosphoric acid, and polypropylene) were used to carbonize jujube branches at high temperatures of 600 °C and 800 °C, and then the PEG/jujube charcoal composite phase change materials (PCM) were prepared by vacuum impregnation of polyethylene glycol (PEG). The results showed that the carbon support activated by polypropylene (PP) had a richer pore size distribution than the other two activation methods, and the 800 °C carbonization carrier loaded PEG had a higher phase change enthalpy than the composite material at 600 °C. The mesoporous and macroporous structures were staggered with PP-activated jujube charcoal at 800 °C, with a specific surface area of 1,082.2 m²/g, the melting enthalpy of the composite material reached 114.92 J/g, and the enthalpy of solidification reached 106.15 J/g after PEG loading. The diffraction peak of the composite phase change material was the superposition of PEG and carbon matrix, which proved that the loading process was physical adsorption. After 200 thermal cycles, the melting enthalpy and crystallization enthalpy were only reduced by 4.3% and 4.1%, respectively, and they remained stable and leak-free at the melting point of PEG for 2 h, demonstrating good thermal stability of the composite phase change materials. In summary, PP has obvious advantages over traditional activation, and the carbon-supported PEG phase change composite after PP activation is a biochar energy storage material with excellent performance.

“…Conventional composite strategies often face the dilemma in improving the charging rate and sacrificing the latent heat storage capacity. , Carbonized biomass has been considered as a desired template to load PCMs and to improve the solar thermal storage physical properties because it has the combined features of 3D conductive network structure and a low density, high absorption of sunlight. As shown in Figure a,b, various biomass made from carbonized watermelons, pumpkins, potatoes, white radishes, rice, etc., have shown the capability to improve solar absorption, thermal conductivity, and leakage-proof properties of PCMs. ,− Carbonized biomass also exhibits good electrical conductivity and thus could realize electrothermal energy storage in PCMs. Tang et al.…”

The regulation and utilization of thermal energy is increasingly important in modern society due to the growing demand for heating and cooling in applications ranging from buildings, to cooling high power electronics, and from personal thermal management to the pursuit of renewable thermal energy technologies. Over billions of years of natural selection, biological organisms have evolved unique mechanisms and delicate structures for efficient and intelligent regulation and utilization of thermal energy. These structures also provide inspiration for developing advanced thermal engineering materials and systems with extraordinary performance. In this review, we summarize research progress in biological and bioinspired thermal energy materials and technologies, including thermal regulation through insulation, radiative cooling, evaporative cooling and camouflage, and conversion and utilization of thermal energy from solar thermal radiation and biological bodies for vapor/electricity generation, temperature/infrared sensing, and communication. Emphasis is placed on introducing bioinspired principles, identifying key bioinspired structures, revealing structure–property–function relationships, and discussing promising and implementable bioinspired strategies. We also present perspectives on current challenges and outlook for future research directions. We anticipate that this review will stimulate further in-depth research in biological and bioinspired thermal energy materials and technologies, and help accelerate the growth of this emerging field.

Phase change materials possess the merits of high latent heat and a small range of phase change temperature variation. Therefore, there are great prospects for applying in heat energy storage and thermal management. However, the commonly used solid‐liquid phase change materials are prone to leakage as the phase change process occurs. To address this drawback of solid‐liquid phase change materials, researchers have developed form‐stable phase change materials. There are three main strategies for preparation of form‐stable phase change materials. The objectives of this article are: (1) The form‐stable phase change materials are classified according to the preparation strategy, and the properties of each class of form‐stable phase change materials are presented. (2) The advantages and disadvantages of form‐stable phase change materials are also discussed. (3) It is also summarized that the methods to improve the drawbacks and enhance the characteristics of form‐stable phase change materials. (4) Moreover, the multifunctional form‐stable phase change materials are also described. (5) Finally, applications of form‐stable phase change materials are analyzed and discussed.
