“…The initial work in this area has shown that by welding the loose natural fibers of the textile, a stronger textile results and that control over the properties of the textile can be adjusted by the amount of IL used to complete the welding. − Trulove et al demonstrated the ability to utilize the mobility of the individual fibers to encapsulate a variety of nanomaterials within a biopolymer matrix using this technique . They showed that a catalyst could be encapsulated in a linen yarn by first coating the yarn with a catalyst ink formed from a suspension of the catalyst in the IL.…”

Ionic liquid based fiber welding has been used to attach the metal−organic framework (MOF) UiO-66-NH 2 to cotton fibers. The results show that by controlling the extent of the welding process, it is possible to produce fibers that contain a high surface area (approximately 50−100 m 2 / g), an X-ray diffraction pattern consistent with UiO-66-NH 2 , and fibers that are chemically reactive to dimethyl 4-nitrophenyl phosphate (DMNP), a common chemical weapon simulant. The ionic liquid/MOF welding solution can be applied by directly placing the fabric in the welding solution or by utilizing an airbrushing technique. Both welding techniques are shown to be scalable with results collected on approximately 1 × 1, 5 × 5, and 15.5 × 15.5 in. swatches. The results are also applicable to weaving methods where the MOF is welded to individual threads and subsequently woven into a textile. The results provide an industrially scalable method of attaching a wide variety of MOFs to cotton textiles, which does not require synthesizing the MOF in the presence of the textile.

“…NFW is quite versatile, as any number of ILs can be applied to natural fiber materials including lignocellulose (e.g., cotton, linen, hemp, bamboo) and other biopolymers (e.g., silk, chitin). Additionally, studies have shown that NFW can maintain or improve the mechanical properties of the underlying natural fiber supports, ,− extending their use to more advanced engineering applications. In previous work, researchers at the U.S.…”

In our study, lignocellulose yarns were fabricated via natural fiber welding (NFW) into a robust, free-standing, sustainable catalyst for water treatment. First, a series of powder catalysts were created by loading monometallic palladium (Pd) and bimetallic palladium−copper (Pd−Cu) nanoparticles onto ball-milled yarn powders via incipient wetness (IW) followed by a gentle reduction method in hydrogen gas that preserved the natural fiber while reducing the metal ions to their zerovalent state. Material characterization revealed Pd preferentially reduced near the surface whereas Cu distributed more uniformly throughout the supports. Although no chemical bonding interactions were observed between the metals and their supports, small (5−10 nm), near-spherical crystalline nanoparticles were produced, and a Pd−Cu alloy formed on the surface of the supports. Catalytic performance was evaluated for each Pd-only and Pd−Cu powder catalyst via nitrite and nitrate reduction tests, respectively. Next, the optimized Pd−Cu linen powder catalyst was fiber-welded onto a macroporous linen yarn scaffold via NFW and its catalyst performance and reusability were evaluated. This fiber-welded catalyst reduced nitrate as effectively as the corresponding powder, and remained stable during five consecutive cycles of nitrate reduction tests. Although catalytic activity declined after the fiber-welded catalyst was left in air for several months, its reactivity could easily be regenerated by thermal treatment. Our research highlights how lignocellulose supported metal-based catalysts can be used for water purification, demonstrating a novel application of NFW for water treatment while presenting a sustainable approach to fabricate functional materials from natural fibers.

“…In recent years, certain ionic liquids (ILs) have been shown to be effective solvents for biopolymers such as cellulose and silk (1,2). Very recently, "natural fiber welding", the selective mobilization and restructuring of biopolymers to create functionalized composite materials, has been demonstrated (3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15). Fiber welding techniques entail the utilization of IL-based solvents to partially solubilize and mobilize biopolymers in (fibrous) natural material substrates.…”

Ionic Liquid-based Solvents for Natural Fiber Welding

et al. 2013

Certain ionic liquids (ILs) are known to be efficient solvents for biopolymers. That said, solvent efficacy is strongly impacted by the presence of both adventitious molecular components and purposeful additives. For example, 1-ethyl-3-methylimidazolium acetate often contains water and acetic acid (polar protic) impurities (by-products of IL synthesis) that can have significant effects upon the dissolution of biopolymers. Additionally, ILs can be mixed with solvents such as acetonitrile (polar aprotic) that also impact the dissolution process. Data are presented that explore the effect of IL-based solvent composition on fiber welding: the controlled, partial dissolution of fibrous materials to create composite materials. Results suggest that IL-based solvents can be tailored for specific outcomes. Additionally, the fiber welding processes and material analysis techniques utilized are themselves useful to quantify solvent efficacy.
