“…In the spectrum of CT900, the characteristic absorption peak at about 3460 cm –1 was due to the stretching vibrations of O–H, and the peak centered at ∼1633 cm –1 was attributed to the stretching vibrations of CO. In the spectrum of PEG, the bands centered at 3400, 2243, and 1470 cm –1 were attributed to the stretching vibrations of O–H groups, and the bands located at 2883 and 1465 cm –1 were due to the stretching vibrations and bending vibrations of C–H groups, respectively . By comparison of the FT-IR spectra of CT900 and PEG, there were no occurrences of additional characteristic peaks for PCC900.…”

The practical application of shape-stable phase change composites (PCCs) is beneficial to thermal energy management and energy conservation due to their superior properties. A shape-stable PCC was fabricated by incorporating poly(ethylene glycol) (PEG) with biomass-based porous carbon that was produced via freeze-drying and carbonization using a low-cost and environmentally friendly fresh towel gourd. The towel gourd derived porous carbon with the characteristics of porosity, unique three-dimensional (3D) lamellar structure, and high specific surface area allowed a high encapsulation capacity (up to 94.5 wt %) for PEG. Structural morphologies, as well as the properties of latent heat storage, thermal reliability, thermal energy management, and thermal protection ability of the fabricated shape-stable PCC, were investigated. The micromorphologies revealed that PEG molecular chains were arranged in a 3D lamellar tissue structure. The shape-stable PCC demonstrated excellent thermal reliability and a high melting latent heat of ∼164.3 J/g. The analysis of infrared thermal images indicated that the shape-stable PCC exhibited remarkable strengths in thermal energy management. The result of the thermal insulation simulation experiment proved that the shape-stable PCC had superior thermal protection ability. This study provided an innovative strategy for the design and development of shape-stable PCCs for great potential in heat-insulating protective textiles, solar thermal energy storage, energy-saving buildings, and infrared stealth of military targets.

“…Currently, the burning of nonrenewable fossil fuels is still the main means for mankind to obtain energy. − However, it produces harmful gases such as CO, CO 2 , and SO 2 , which not only pollute the natural ecology but also harm human health. , Therefore, the development and utilization of clean, resource-rich, and renewable solar energy has become a current research hotspot. − Like other renewable natural energy sources, solar energy has the characteristics of intermittent and instability, and therefore, it could not meet human demand for sustainable energy. , In order to obtain long-term and stable solar energy, energy storage technologies have been introduced into the field of solar energy utilizations. Among various energy storage technologies, the latent heat energy storage technology using organic solid–liquid phase change materials (PCMs) as the working material has the advantages of high energy storage density, constant temperature during energy storage/release, and convenient operation. − Therefore, organic solid–liquid PCMs have aroused wide interest among researchers.…”

For enhancing the heat storage and encapsulation performances of organic phase change materials (PCMs), a carbon foam (CF) with a continuous dual-scale pore structure (DCF) was developed. Employing the as-prepared DCF as a stearic acid (SA) support, a novel shape-stabilized SA–CF composite PCM with a continuous dual-scale interpenetrating network structure was achieved through the impregnation of SA into the DCF. DCF-900, prepared at an activation temperature of 900 °C, possesses a high loading capacity of 89.54 wt % for melted SA without leakage. The resulting SA/DCF-900 composite with a continuous dual-scale interpenetrating network structure exhibits excellent comprehensive performances with a good synergistic effect. The composite presents a thermal conductivity of 1.298 W/m·K and an encouraging compressive strength of 9.03 MPa, which increase by 2.25-fold and 3.56-fold compared with those of DCF-900, respectively. Furthermore, its melting and freezing enthalpies reach 192.8 and 192.7 J/g with a storage efficiency of about 100%, respectively; meanwhile, it displays excellent thermal cycle stability and reversibility after 600 thermal cycles with a high melting/freezing enthalpy retention rate of up to 96%. More importantly, its light-to-thermal conversion efficiency reaches 91.8% under a light intensity of 100 mW/cm2. Consequently, the SA/DCF-900 composite is a promising candidate for high-performance PCMs.
