“…Engineered hydrogels and gel‐derived fibers are nascent and appealing soft matters, particularly in contexts of advanced wearables, [1–2] electronic devices, [3–5] drug delivery, [6] cosmetics, [7] food technology, [8] and smart behavior system, [9] due to their high stretchability, flexibility, hybrid networks, and diverse functionalities. However, those gel fibers show inferior mechanical properties, such as low fracture toughness, modulus, and strength (Table 1).…”

Hydrogels enable a variety of applications due to their dynamic networks, structural flexibility, and tailorable functionality. However, their mechanical performances are limited, specifically in the context of cellular mechanobiology. It is also difficult to fabricate robust gel networks with a long‐term durability. Thus, a new generation of soft materials showing outstanding mechanical behavior for mechanobiology applications is highly desirable. We combined synthetic biology and supramolecular assembly to prepare elastin‐like protein (ELP) organogel fibers with extraordinary mechanical properties. The mechanical performance and stability of the assembled anisotropic proteins are superior to other organo‐/hydrogel systems. Bone‐derived mesenchymal cells were introduced into the organofiber system for stem‐cell lineage differentiation. This approach demonstrates the feasibility of mechanically strong and anisotropic organonetworks for mechanobiology applications and holds great potential for tissue‐regeneration translations.

“…To overcome the low viscosity of monomer solutions, which leads to the breakage of nascent fiber, a precursor (containing monomers, initiators and crosslinkers) usually polymerizes in tubular templates, which are lubricated or super-hydrophobic [ 37 ]. Although fibrous hydrogels with millimeter levels of thickness (thin fibers are poorly demoldable) have been fabricated by such reactive spinning methods, its industrialization has encountered challenges to achieving high-speed manufacturing and obtaining fibers at the micrometer level [ 38 ]. In comparison, the more scalable spinning route in the textile industry is by constructing networks using macromolecules.…”

Macroscopic hydrogel fibers are highly desirable for smart textiles, but the fabrication of self-healable and super-tough covalent/physical double-network hydrogels is rarely reported. Herein, copolymers containing ketone groups were synthesized and prepared into a dynamic covalent hydrogel via acylhydrazone chemistry. Double-network hydrogels were constructed via the dynamic covalent crosslinking of copolymers and the supramolecular interactions of iota-carrageenan. Tensile tests on double-network and parental hydrogels revealed the successful construction of strong and tough hydrogels. The double-network hydrogel precursor was wet spun to obtain macroscopic fibers with controlled drawing ratios. The resultant fibers reached a high strength of 1.35 MPa or a large toughness of 1.22 MJ/m3. Highly efficient self-healing performances were observed in hydrogel fibers and their bulk specimens. Through the simultaneous healing of covalent and supramolecular networks under acidic and heated conditions, fibers achieved rapid and near-complete healing with 96% efficiency. Such self-healable and super-tough hydrogel fibers were applied as shape memory fibers for repetitive actuating in response to water, indicating their potential in intelligent fabrics.

“…To circumvent this issue, recently Ma et al reported a core–shell stretchable and conductive sodium polyacrylate hydrogel microfiber with a thin elastomer coating layer to prevent dehydration while maintaining good fiber elasticity 14. Nonetheless, the inert elastomer coating evitably leads hydrogel microfiber to be insensitive to environmental changes, which are unfavorable for sensing applications. Spinnability versus fiber strength: compared to electrospinning15,16 and extrusion spinning,9,10,17,18 microfluidic or draw‐spinning inspired from spider spinning procedure11–14,19,20 seems to be more suitable for fabricating long and uniform hydrogel microfibers. However, unless using the strategy of full dehydration, it is still challenging to compromise the spinnability and mechanical strength of hydrogel microfibers.…”

Stretchable hydrogel microfibers as a novel type of ionic conductors are promising in gaining skin‐like sensing applications in more diverse scenarios. However, it remains a great challenge to fabricate coating‐free but water‐retaining conductive hydrogel microfibers with a good balance of spinnability and mechanical strength. Here the old yet significant redox chemistry of Fe‐citrate complex is employed to solve this issue in the continuous draw‐spinning process of poly(acrylamide‐co‐sodium acrylate) hydrogel microfibers and microfiber nets from a water/glycerol solution. The resultant microfibers are ionically conductive, highly stretchable, and uniform with tunable diameters. Furthermore, the presence of redox‐reversible Fe‐citrate complex and glycerol endows the fibers with good anti‐freezing, water‐retaining, and environmentally intelligent properties. Humidity and UV light can finely mediate the stiffness of hydrogel microfibers; conversely, the ionic conductance of microfibers is also responsive to light, humidity, and strain, which enables the highly sensitive perception of environmental changes. The present draw‐spinning strategy provides more possibilities for coating‐free conductive hydrogel microfibers with a variety of responsive and sensing applications.
