Thermal energy storage can contribute to the reduction of carbon emissions, motivating the applications in aerospace, construction, textiles and so on. Phase change materials have been investigated extensively in the field of high-performance intelligent thermoregulating fabrics for energy storage. Advances toward fibers or fabrics for thermo regulation are developed, but leakage of phase change medium is a concern when directly coated or filled with fibers or fabrics. Thus, different spinning methods have appeared to integrate phase change materials into copolymer fiber to prepare phase change fiber. The present review has been divided into three parts and first deals with spinning technologies such as wet spinning, melt spinning, electrostatic spinning, and centrifugal spinning with the thermal properties and mechanical properties of phase change fiber. Among them, the phase change medium loading in the phase change fiber with wet spinning is up to 70 wt.%, while the fiber strength is below 2.12 cN/dtex. In contrast, phase change fiber prepared by melt spinning achieves a breaking strength of up to 37.31 cN/dtex, but with an enthalpy of only 8.48 kJ/kg. Considering electrostatic spinning, not only enthalpies are satisfactory but the fiber diameters are mostly below 1000 nm, matching with the softness requirement for fabric. Moreover, centrifugal spinning enables efficient production of phase change fiber of large enthalpy by controlling spinning parameters such as rotational speed and spinning fluid concentration. The second part reports that the thermal management effects of different intelligent thermo regulating fabrics are evaluated by designed experiments or simulations to investigate further the more comfortable conditions of thermal comfort of humans. Simulation and experimental results show that the energy storage of smart fabrics extends the time duration of thermal comfort by more than 300 s. In the last part, multifunctional intelligent thermoregulating fabrics are systematically discussed, such as light and heat response, ultraviolet resistance, air permeability, and water resistance. Practical applications of phase change fibers and intelligent thermoregulating fabrics should be further studied and broadened in the future.

“…To overcome the limitations of the low production rate and safety concerns of electrospinning, a safe and massive centrifugal spinning technology has been developed to extrude flexible phase change fibers because no high voltage is required, and its fibrous production rate is hundreds-fold faster than that of electrospinning. [146] Compared to the foregoing techniques, melt spinning, [48,147] a more facile and high-efficiency spinning strategy, has been employed for the mass production of phase change fibers (Figure 10a). Most recently, porous aerogel fibers prepared by freeze-drying [62,148] and supercritical gas drying [49,59] have been developed to serve as new carriers for phase change fibers.…”

As one of the main forms and intermediate carriers of energy, it is impressive to expand the application scope of heat energy, thereby boosting innovations in heat harvesting, conversion, storage, regulation, and utilization associated with the relevant techniques. Phase change materials (PCMs), as a state-of-the-art latent heat storage technique, have garnered increasing interest in heat-related applications over the past decades, and abundant high-performance PCMs with excellent shape stability and salient thermal conductivity have been developed. This review focuses on the issues concerning organic PCMs from the perspectives of flexible, multifunctional, and smart phase change composites, along with emerging applications and processing technologies, which are expected to offer possible guidance for the exploration of next-generation advanced functional phase change composites.

“…As an emerging composite material, flexible composite PCMs have become a research hotspot in recent years because of their ability to withstand certain deformations. − In general, flexibility is a concept related to rigidity that emphasizes the deformability of materials with linear elasticity, inelasticity, or plasticity in the stress–strain relationship. Compared with SS-CPCMs, flexible composite PCMs generally have the characteristics of being bendable, foldable (or twistable), and stretchable, and their properties remain unchanged after a certain deformation. , On the basis of the application scenarios of the flexible composite PCMs, the selection of suitable support materials and flexible strategies is crucial for flexible composite PCMs. Generally, the support body must be compatible with the PCMs and have certain flexibility and elasticity.…”

With the continuous expansion of the research and development and application fields of phase change materials (PCMs), more and more attention has been paid to shape-tunable flexible composite PCMs, which have become a research hotspot in recent years. Flexible composite PCMs can be attached strongly to objects under a certain degree of deformation, thereby giving them great potential in smart applications. This paper reviews the design and fabrication strategies of flexible composite PCMs. The applications of flexible composite PCMs in various fields, such as temperature control of electrical equipment, the textile industry, and multifunctional applications, are introduced in detail. Finally, the challenges, gaps, and perspectives are put forward and discussed. This insightful review aims to provide an in-depth understanding and constructive guidance on flexible composite PCMs.
