“…As a result, the intelligent textiles with PCM on the surface had a significantly longer cooling process. Zhang et al 102 exposed the smart fabric to sunlight at a temperature of 12.5 C and recorded the cooling process by a thermal infrared imager for every 60 s. The results showed that the delay of smart fabric to heat dissipation could reach 120-180 s.…”

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.

The utilization of the paraffin phase change material (PCM) in solar energy storage systems is limited by its low thermal conductivity, easy leakage, and insensitivity to solar energy. In the present study, the solution combustion synthesis method was applied to fabricate a porous carbon matrix that is embedded with Cu nanoparticles (Cu@C). The shape-stabilized composite PCM was prepared by vacuum impregnation of liquified paraffin. The paraffin/Cu@C composite retained a high latent heat storage enthalpy of 148.2 J/g. The thermal conductivity of the composite was increased to 145% compared to that of pure paraffin. Due to the strong capillary absorption feature of the porous matrix, the composite also indicated a good anti-leakage property. Additionally, the Cu@C matrix also endowed the composite PCMs with good photo-thermal transformation capability, implying their potential application in solar thermal energy storage.

“…Microencapsulation, polymer addition and impregnation of porous materials are often used to solve the problem of shape stability. Zhang et al used methyl methacrylate as wall material, solid paraffin and butyl stearate as core material to prepare PCMs microcapsules, which solved the instability of PCMs (Zhang et al, 2020a(Zhang et al, , 2020b. Zhu et al prepared novel nano encapsulated n-octadecane PCMs, the organosilica wall as a physical protective barrier that slows the escape of the volatile products during the heating process and the thermal stability of the as-prepared samples are improved (Zhu et al, 2015).…”

Purpose Fabrics with photothermal conversion functions were developed based on the introduction of shape stable composite phase change materials (CPCMs). Design/methodology/approach Acidified single-walled carbon nanotubes (SWCNTs) were selected as support material to prepare CPCMs with n-octadecane to improve the thermal conductivity and shape stability. The CPCMs were finished onto the surface of cotton fabric through the coating and screen-printing method. The chemical properties of CPCMs were characterized by Fourier transform infrared spectrometer, XRD and differential scanning calorimetry (DSC). The shape stability and thermal conductivity were also evaluated. In addition, the photothermal conversion and temperature-regulating performance of the finished fabrics were analyzed. Findings When the addition amount of acidified SWCNTs are 14% to the mass of n-octadecane, the best shape stability of CPCMs is obtained. DSC analysis shows that the latent heat energy storage of CPCMs is as high as 183.1 J/g. The thermal conductivity is increased by 84.4% compared with that of n-octadecane. The temperature-regulating fabrics coated with CPCMs have good photothermal conversion properties. Research limitations/implications CPCMs with high latent heat properties are applied to the fabric surface through screen printing technology, which not only gives the fabric the photothermal conversion performance but also reflects the design of personalized patterns. Practical implications CPCMs and polydimethylsiloxane (PDMS) are mixed to make printing paste and printed cotton fabric with temperature-regulating functional is developed. Originality/value SWCNTs and n-octadecane are composited to prepare CPCMs with excellent thermal properties, which can be mixed with PDMS to make printing paste without adding other pastes. The fabric is screen-printed to obtain a personalized pattern and can be given a thermoregulatory function.
