“…To solve the contradiction and/or mismatch between economic development and energy demand, renewable and sustainable energies can be utilized to decrease fossil fuel consumption and thus relieve environmental pollution. Energy storage technology has been introduced to convert and store unnecessary or excess energy for reuse. − There is a wide range of thermal energy, and a large amount of latent heat can be stored through phase change behavior of phase change materials (PCMs), which can be used in passive heat-regulating building systems, , solar energy storage and utilization, − agricultural greenhouse, road traffic, thermal insulation, temperature-regulated textiles, and so on. In particular, solid–liquid PCMs are believed to be ideal thermal energy storage media by virtue of their high-energy storage density, long-term usability, high physical/chemical stability, negligible supercooling, and noncorrosiveness.…”

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.

In this work, a new composite phase change material (CPCM) with lauric-myristic acid (LA-MA) eutectic as PCM and activated carbon (AC) was used as supporting material with four different mass ratios of 5.0:5.0, 5.5:4.5, 6.0:4.0, and 6.5:3.5, respectively. The properties and microstructure of LA-MA/AC were analyzed by some characterization methods. The results show that the composite process of LA-MA eutectic and AC was a simple physical mixing and no new chemical bonds were found. The fusion and freeze temperature, enthalpy of the samples were measured by differential scanning calorimetry (DSC), and the residual weight of the samples was analyzed by thermogravimeter (TGA). It was shown that the fusion and freeze temperature of LA-MA eutectic separately were 32.42 ℃ and 33.63 ℃, and its fusion enthalpy and freeze enthalpy were 152.64 J/g and 148.8 J/g, respectively. TGA data shows that the thermal stability of LA-MA eutectic was obviously improved by adding AC as a support material. The results of this study can be available for reference to solar energy storage applications.

With the expansion of the global population, the energy shortage is becoming increasingly acute. Phase change materials (PCMs) are considered green and efficient mediums for thermal energy storage, but the leakage problem caused by volume instability during phase change limits their application. Encapsulating PCMs with supporting materials can effectively avoid leakage, but most supporting materials are expensive and consume huge of natural resources. Carbon materials, which are rich and renewable resources, can be used as economical and environmentally friendly supporting skeletons to prepare form‐stable PCMs. Although many researchers have begun to use recyclable materials especially various derivatives of carbon as supporting skeletons to prepare form‐stable PCMs, the preparation methods, thermophysical properties and applications of form‐stable PCMs with recyclable skeletons have rarely been systematically summarized yet. Form‐stable PCMs with a recyclable skeleton can be used as green and efficient thermal storage materials due to their high heat storage capacity and good thermophysical stability after 2000 thermal cycles. This review investigates the effects of recyclable skeletons on the thermophysical properties including phase change temperature, latent heat, thermal conductivity, supercooling, and thermal cycling reliability. Four major kinds of recyclable skeletons are focused on: biomass, biochar, industrial by‐products as well as waste incineration ash. Additionally, the application scales of form‐stable PCMs with recyclable skeletons are explicated in depth. Moreover, the main challenges confronted by form‐stable PCMs with recyclable skeletons are discussed, and future research trends are proposed. This article provides a systematic review of the form‐stable PCMs with recyclable skeletons, giving significant guidance for further reducing carbon emissions and promoting the development of sustainable energy.
