“…[61] As a quick remark, our phase-change fibers achieve a good balance of high phase-change properties and mechanical strength, surpassing most results in the literature (Figure 6g). [7,28,29,35,50,[62][63][64][65] The deterioration of the performance of composite systems in long-term usage is challenging, especially for cellulosic materials [66] In order to examine the durability of the present CNF/MoS 2 /PCM fibers for thermal-regulating applications, fibers were fabricated into a thin cloth (Figure 7a) and then placed on a thermal block set on a dry bath incubator, which can realize a programed temperature control and a thermocouple was used to monitor the surface temperature evolution (Figure 7b). In the first set-up, the temperature was switched between 42 and 22 °C to simulate the scenario where one has to transfer frequently between indoors and outdoors on hot days with large temperature disparity (Figure 7c).…”

“…[46,47] In addition, CNFs have been reported to act as a stabilizer for paraffin-based PCM via Pickering emulsification, [48,49] as an alternative to conventional synthetic surfactants. [50] Therefore, CNF-based wet-spun fibers hold great potential to be used in the field of photothermal energy utilization and storage, while studies have normally used simple mixing or coating methods to incorporate the functional components. This does not utilize the potential of CNFs in the assembled fiber materials, which can serve as dispersing agents and stabilizers, as well as the continuous matrix with superior mechanical support.…”

Flexible fibers and textiles featuring photothermal conversion and storage capacities are ideal platforms for solar‐energy utilization and wearable thermal management. Other than using fossil‐fuel‐based synthetic fibers, re‐designing natural fibers with nanotechnology is a sustainable but challenging option. Herein, advanced core–shell structure fibers based on plant‐based nanocelluloses are obtained using a facile co‐axial wet‐spinning process, which has superior photothermal and thermal‐regulating performances. Besides serving as the continuous matrix, nanocelluloses also have two other important roles: dispersing agent when exfoliating molybdenum disulfide (MoS2), and stabilizer for phase change materials (PCM) in the form of Pickering emulsion. Consequently, the shell layer contains well‐oriented nanocelluloses and MoS2, and the core layer contains a high content of PCM in a leak‐proof encapsulated manner. Such a hierarchical cellulosic supportive structure leads to high mechanical strength (139 MPa), favorable flexibility, and large latent heat (92.0 J g−1), surpassing most previous studies. Furthermore, the corresponding woven cloth demonstrates satisfactory thermal‐regulating performance, high solar‐thermal conversion and storage efficiency (78.4–84.3%), and excellent long‐term performance. In all, this work paves a new way to build advanced structures by assembling nanoparticles and polymers for functional composite fibers in advanced solar‐energy‐related applications.

“…Smart textiles are textiles that incorporate material, biological, chemical, and electronic information technologies to perceive, react, adjust, or adapt to different stimuli . For instance, adding chromophores with different concentrations in textiles can be used to detect odorless and colorless nerve agents, while the nanofibers obtained by encapsulating PSiN with polyacrylonitrile or hydrogels containing nanoparticles coated on the surface of textiles can be used for anticounterfeiting .…”

Nanogels Containing Gold Nanoparticles on Cotton Fabrics for Comfort Control via Localized Surface Plasmon Resonance

The wearing comfort of fabrics is strongly related to moisture permeability and thermal insulation. To enhance comfort, the localized surface plasmon resonance (LSPR) effect is applied on cotton fabrics by densely packed hybrid nanogels containing gold nanoparticles on the surface. The nanogels are prepared by emulsion polymerization using di(ethylene glycol) methyl ether methacrylate (MEO 2 MA), (ethylene glycol) methyl ether methacrylate (OEGMA 300 ), and ethylene glycol methacrylate (EGMA) as monomers. Because of the different transition temperatures of MEO 2 MA (25 °C) and OEGMA 300 (60 °C), the obtained nanogels present a linear shrinkage behavior between 20 to 50 °C. Further treated with in situ reduction, gold nanoparticles (Au NPs) are embedded in the nanogels. After cross-linking the hybrid nanogels onto cotton fabrics and exposure to visible light irradiation (0.1029 W), the ratio of moisture permeability of the cotton fabrics cross-linked with hybrid nanogels (weight gain ratio, WGR of 8%) at 30 °C to that at 20 °C is 1.67. It is 45% better than that of cross-linked pure nanogels without any Au NPs. When the WGR is increased to 15%, the ratio is up to 2.18, thereby almost doubling that of the cross-linked pure nanogels. Such improvement is caused by the LSPR effect from the densely packed hybrid nanogels on the cotton fabric, which induces a more efficient photothermal conversion and prominent shrinkage of the hybrid nanogels. In addition, because the Au NPs can well absorb light irradiation, the cotton fabrics cross-linked with hybrid nanogels are able to efficiently shield the incident light and present a good capability of heat insulation. Therefore, the obtained cotton fabrics can adjust their comfort according to the external light conditions, well suited for outdoor scenarios such as running and hiking.
