The development of sustainable and recyclable adhesives simultaneously requiring high strength and ductility is challengeable. Herein, we synthesized furan ring-containing copolyesters as sustainable, strong, and tough adhesives. FTIR and 1H NMR analyses confirmed the successful synthesis of copolyesters. Furthermore, structures and physiochemical properties of copolyesters were easily tunable by varying the feeding ratio of comonomers. The obtained copolyesters exhibited several interesting features as adhesives, which synergistically resulted in superior adhesion behavior, including high adhesion strength (12.60 MPa), satisfactory toughness (work of debonding = 2623 N m–1), wide temperature adaptability (adhesion strength = 8.23 MPa at −70 °C and 3.83 MPa at 100 °C), and excellent solvent resistance (9.27 MPa of adhesion strength in N,N-dimethylformamide after 24 h). The present work significantly advances and provides perspectives on the design of strong and tough sustainable adhesives.

The excessive reliance on traditional petroleum resources poses significant environmental challenges. Fortunately, agricultural straw, which is often regarded as a waste product, has considerable potential for various applications. However, these materials are frequently crushed into particles, thereby neglecting their inherent structural advantages. In this study, wheat straw is utilized in its complete form and converted to a strong and flexible fiber bundle. We employ a top-down approach on whole wheat straw that involves an alkali pretreatment combined with delignification and freeze-drying to obtain highly directional cellulose aggregates. Subsequent twist densification results in the formation of a strong, flexible wheat straw-derived fiber bundle (WFB). WFB exhibits an excellent strength of 203.9 MPa, representing a 3.4 improvement rate in relation to that of the initial straw. This indicates that agricultural waste can be transformed to a high-performance material, embodying the concept of “Waste to Wealth.” In addition, WFB can be further functionalized (e.g., via hydrophobic treatment, dyeing treatment, or incorporation with a conductive material) on the basis of the abundant hydroxyl groups present on its surface. This strategy provides insights into the innovative utilization of straw and promotes its application in wearable textile and smart fiber development.

Elastomers with high strength and toughness, excellent self-healing properties, and biocompatibility have broad application prospects in wearable electronics and other fields, but preparing it remains a challenge. In this work, we propose a highly adaptable strategy by introducing the small molecule crosslinking agent of triethanolamine (TEA) to the poly thioctic acid (PTA) chains and preparing the PA x E y elastomers using a simple synthesis step. This strategy stabilizes the PTA chains by constructing multiple non-covalent cross-linked dynamic networks, endowing materials with excellent strength and toughness (tensile strength of 288 kPa, toughness of 278.2 kJ/m 3 ), admirable self-healing properties (self-healing efficiency of 121.6% within 7 h at 70 °C), and good biocompatibility. The PA x E y elastomers can also be combined with MWNTs to become flexible strain sensors, which can be used to monitor human joint movements with high sensitivity, repeatable responses, and stability.

Stretchable eutectogel fibers hold exceptional promise for human physiological monitoring wearable electronics due to their nonvolatility, high ionic conductivity, and cost-effective fabrication. However, a significant challenge remains in achieving sufficient mechanical properties of eutectogel fibers for textile manufacturing and the ability to withstand long-term real-life usage, such as sweating and washing. Herein, hydrophobic eutectogel fibers (HEFs) with exceptional mechanical strength and environmental resilience were prepared via integrating prestretching and solvent evaporation-induced crystallization processes. The formation of abundant hydrogen bonds and the crystallization domain impart the HEFs with excellent tensile strength (5.5–22.5 MPa) and adjustable stretchability (75–375%). Most importantly, the HEF fibers keep remarkable stability (weight changes <2%) in aquatic environments under varying conditions of pH, humidity, detergent, and temperature. The HEF demonstrated multimodal sensing capabilities, including motion, weight, and temperature detection, with high-precision sensation (gauge factor = 2.2; temperature coefficient of resistance = 4.83 ± 0.2% K–1) and stability. These advancements set a foundation for smart wearable devices, marking a significant progress in the fields of eutectogel-based intelligent health monitoring.

HfO 2 is an important high temperature resistant material, which has a high melting point (2810 °C), good chemical stability and high thermal radiation. Fibrous material has some advantages for heavy refractory matter, such as large aspect ratio, light weight, more energy saving, flexibility and further can be processed into a variety of product forms. In this paper, high strength HfO 2 crystalline nanofibers were prepared through self-synthesis polyacetylcatonahafnium (PAHf) with electrospinning method. Phase variation process was discussed in detail, and the HfO 2 fibers that use Y 2 O 3 as stabilizer with phase stability were prepared finally. The fibers were composed of nanocrystals with good flexibility even folded in half, tensile strength of 1.6 MPa @ 1000 °C and can lifting up 1288 times its own weight, low density around 35 mg/cm 3 . The thermal conductivity was stable around 26 mW / (m·K) @ 1200 °C and the temperature can be cooled from 1200 °C to 396 °C after 180 s through 7 mm fibrous membranes .

The development of shape deformation hydrogels has aroused interests of their immense applications in diverse fields such as actuators, soft robotics, and artificial muscles. However, the existing deformable hydrogels can hardly meet the requirements of facile preparation, excellent mechanical properties and reversible shape memory, which greatly limits their further applications. In this work, a new type of fully physically cross-linked deformable hydrogel with mechanically strong, tough, stretchable, and solvent-responsive property is fabricated via free radical polymerization at room temperature, followed by immersed in a Fe 3+ aqueous solution. The strong physical interactions of polyacrylic acid (PAA)-Fe 3+ metal complexation and hydrogen bond endowed this hydrogel with high tensile strength (~5.14 MPa), high stretchability (~1000%), high toughness (~20.36 MJ/m 3 ) and excellent flexibility (~0.53 MPa). In addition, programmable shape deformation hydrogel is achieved by selective coating of Fe 3+ on surface, the hydrogel strips can be deformed into arbitrary shapes such as the letter “o”, “d”, “s”, and “w”. More impressively, reversible shape recovery of hydrogel has been achieved via two methods: the elimination of coated Fe 3+ with the reaction of NaOH and the dehydration of the glycerin. Taking advantage of this property, we simulate the closure and opening of hydrogel flower by soaking it into water and NaOH/glycerin alternately. Moreover, the soft robotic gripper has been fabricated based on the mechanically strong and solvent-triggered hydrogel, capable of grabbing about 1.56 times its own weight, which indicating the potential application as load-carrying soft robots.

Architected hydrogels are widely used in biomedicine, soft robots, and flexible electronics while still possess big challenges in strong toughness, and shape modeling. Here, inspired with the universal hydrogen bonding interactions in biological systems, a strain-induced microphase separation path toward achieving the printable, tough supramolecular polymer hydrogels by hydrogen bond engineering is developed. Specifically, it subtly designs and fabricates the poly (N-acryloylsemicarbazide-co-acrylic acid) hydrogels with high hydrogen bond energy by phase conversion induced hydrogen bond reconstruction. The resultant hydrogels exhibited the unique strain-induced microphase separation behavior, resulting in the excellent strong toughness with, for example, an ultimate stress of 9.1 ± 0.3 MPa, strain levels of 1020 ± 126%, toughness of 33.7 ± 6.6 MJ m −3 , and fracture energy of 171.1 ± 34.3 kJ m −2 . More importantly, the hydrogen bond engineered supramolecular hydrogels possess dynamic shape memory character, i.e shape fixing at low temperature while recovery after heating. As the proof of concept, the tailored hydrogel stents are readily manufactured by 3D printing, which showed good biocompatibility, load-bearing and drug elution, being beneficial for the biomedical applications. It is believed that the present 3D printing of the architected dynamic hydrogels with ultrahigh toughness can broaden their applications.

Strong and tough hydrogels have gained popularity for various applications; however, their fabrication remains challenging, particularly when incorporating functionalities. Here, we describe a novel facile multiscale biomimetic strategy that combines molecular and structural engineering to fabricate strong and tough hydrogels. More specifically, a non-covalent-bonding-driven self-assembled cellulose skeleton is embedded in a polyacrylamide matrix. Water-induced cellulose self-assembly facilitates the production of a biomimetic design. The resulting hydrogel exhibited unique interesting features, including the hierarchical structure of the skin, molecular-scale regulation of the enhanced skeleton, and incorporation of physical interfacial interactions. The resultant hydrogels showed excellent tensile strength, toughness and stretchability, with antibacterial, anti-freezing, and adhesive properties desirable for sensor applications. This study proposes an effective strategy that can be used to overcome the challenge of the mutual exclusivity of high strength and toughness and circumvent the trade-off between functionalities and mechanical properties. Thus, this study provides new insights for designing strong and tough hydrogels.

The development of biodegradable and environmental friendly wrap sizing agent is beneficial for reducing the impact of textile desizing effluent on environment. In this work, green and biodegradable keratin sizing agent with enhanced toughness and tenacity was prepared by adjusting side chain tails structure via thiol-ene click chemistry grafting modification for warp yarn slashing against film thermal-embrittlement and fracture during weaving. Feather keratin from waste feather has become an attractive target to replace petroleum-based Poly (vinyl alcohol) sizes due to its easy film-forming ability, excellent adhesive property, biodegradability and low cost. However, keratin yarn coating showed brittleness and easily peeled off from weaving yarn which highly restrict its application. Thus, polymer branched side chain tails with a structure that similar to the wrap yarn was grafted onto keratin molecular chain by utilizing its distinctive thio group as anchor point by means of click chemistry. The results showed that grafting modification could obviously improve the adhesiveness of keratin sizing by the principle of similarity compatibility. The sizing performance, desizing performance as well as its degradability were comprehensively studied. Successful utilization of modified keratin sizes will bring opportunities for the green and sustainable development of textile industry.

Rubber-like soft materials can be modeled by the statistical behavior of polymer chains and the network theory within the framework of thermodynamics. For example, the freely jointed chain model describes the deformation behavior of a single chain and the eight-chain network model relates the chain behavior to the macroscopic deformation . The emerging soft hydrogel materials with superior toughness contain additional constituents rather than one polymer network and thus have complex interplays when subject to external forces. For the double-network hydrogels, the existence of a second sacrificial network, serving as a source of energy dissipation , makes the stress-stretch curves exhibit a strain-softening behavior, which cannot be modeled by the freely jointed chain model. In this work, we develop a constitutive model for the strain-softening behavior of tough hydrogels. We introduce an internal variable to the free energy function of a single chain and then map the deformation of chains to the macroscopic deformation of polymer network. We synthesize different kinds of tough hydrogels and conduct uniaxial tension experiments. We demonstrate that the present model has a wide range of tunability and is capable of modeling the quasi-static tension of tough hydrogels with different chemical compositions, the irreversible damage behavior of chemically crosslinked hydrogels, the recoverable behavior of physically crosslinked hydrogels, the Mullins effect and the rate-dependent behaviors. These results enrich the large deformation theory and extend the classical constitutive models to capture the new features in the emerging soft and tough materials.

A small-scale delivery medium for CO 2 laser energy with stable performance, flexibility, and high-strength is crucial in extreme laser processing environments, especially for minimally invasive surgery in high-humidity, twisty and narrow channels. Here, flexible and robust multimaterial infrared fibers made of selenium-based chalcogenide glasses and thermoplastic polymer were developed with a low loss of 7.18 dB/m at 10.6 μm. The resulting fibers were capable of stably delivering single-mode CO 2 laser with 0.42 W average power. Moreover, to achieve precise control over the fibers in the practical clinical environment, customized co-polymers of polyphenylene sulfone resin and polyvinylidene fluoride were used as the fiber built-in jackets. Consequently, the fibers exhibited hydrophobicity, thermostability, high tensile strength, and low bending stiffness. The results demonstrated that the fibers can be used to deliver CO 2 laser energy for fabric cutting and bio-tissues ablation, making them attractive for CO 2 laser material processing and minimally invasive laser surgery.

Owing to their high strength and high toughness, ionically conductive elastomers have wide application prospects in artificial muscle materials, lithium-ion batteries and other fields. In this work, on the basis of a polymerizable deep eutectic solvent (DES) prepared from acrylic acid (AA) and choline chloride (ChCl) and N-(2-hydroxyethyl) acrylamide (HEAA) monomers, a high-strength and high-toughness ionic conductive elastomer P(DES–HEAA) was successfully prepared via one-step photopolymerization without the use of any chemical crosslinking agents. The elastomer not only has excellent mechanical properties (tensile strength: 15.59 MPa, tensile strain: 521%, Young's modulus: 652.3 MPa, toughness: 56.2 MJ m−3) but also has high transparency, satisfactory conductivity, good shape memory and excellent anticutting and wear resistance. Owing to the simple and fast preparation process (light irradiation for 10 min) and the excellent properties of the obtained elastomers, this study provides a novel and effective strategy for the development of high-strength, high-toughness, and damage-resistant ionic conductive elastomers.
