“…PCM with latent heat, phase change temperature, hydrophobicity, stable shape, and high temperature resistance still needs further exploration, and it might be an effective strategy to introduce a nano-porous carrier for PCM adsorption or replacing hydrophilic groups in PCM by a molecular design to improve high temperature stability and washing resistance of the fiber, respectively. 33,[45][46][47][48][49][50][51][52][53][54][55]…”

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.

Polyurethane (PU) is a traditional chemical known for its chemical stability and mechanical performance. Inspired by the similarity between the formation and breakage of chemical coordination bonds and the energy storage and release of muscle fibers, muscle‐like electrostatically spun fibers with acid‐responsive energy storage and release were prepared by introducing bio‐inspired elastic energy storage groups and bio‐active degradation groups (PU‐BPY‐Fe) in the main chain of PU, taking advantage of the good mechanical properties of PU. The fabricated electrospinning film PU‐BPY‐Fe can respond to external stimulation, which generated high strain (32 MPa), stretch of 206%, outperforming the nanofiber membrane before stimulation, similar and even higher than the biological muscles. The variable mechanical properties and elastic energy storage capacity of PU‐BPY‐Fe were attributed to the reversible hydrogen bonding and the destabilization of metal coordination bonds (Fe3+ to Fe2+) within the material under acidic stimulation. Cytotoxicity testing of the synthesized fibers indicated a degree of biocompatibility, suggesting potential for in vivo applications. This method of storing and releasing elastic energy was demonstrated and has endowed the PU‐BPY‐Fe with stimuli‐responsibility and muscle‐like mechanical properties, which may inspire the design of soft muscles materials for robots and tissue engineering applications.

Polyamide 6 (PA6) fiber has the advantages of high strength and good wear resistance. However, it is still challenging to effectively load inorganic antibacterial agents into polymer substrates without antimicrobial activity. In this work, graphene oxide is used as a carrier, which is modified with an aminosilane coupling agent (AEAPTMS) to enhance the compatibility and antimicrobial properties of the inorganic material, as well as to improve its thermal stability in a high‐temperature melting environment. Cuprous oxide‐loaded aminated grapheme (Cu2O‐GO‐NH2) is constructed by in situ growth method, and further PA6/Cu2O‐GO‐NH2 fibers are prepared by in situ polymerization. The composite fiber has excellent washing resistance. After 50 times of washing, its bactericidal rates against Bacillus subtilis and Escherichia coli are 98.85% and 99.99%, respectively. In addition, the enhanced compatibility of Cu2O‐GO‐NH2 with the PA6 matrix improves the orientation and crystallinity of the composite fibers. Compared with PA6/Cu2O‐GO fibers, the fracture strength of PA6/Cu2O‐GO‐NH2 fibers increases from 3.0 to 4.2 cN/dtex when the addition of Cu2O‐GO‐NH2 is 0.2 wt%. Chemical modification and in situ concepts help to improve the compatibility of inorganic antimicrobial agents with organic polymers, which can be applied to the development of medical textiles.
