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.

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.

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.

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.

Phenolic resins are widely used for outdoor and structural wood-based panels; however, they are challenged by high curing temperatures, low curing rates, and high brittleness. Inspired by lobster epidermis hardening, a tough, strong, and fast-curing phenolic resin (named DCS/PG/PF) was proposed herein. In this approach, dopamine-grafted chitosan (DCS) and polyethyleneimine-functionalized graphene (PEI@G) were incorporated into neat phenol formaldehyde (PF) resin. The gel time and maximum curing temperature of DCS/PG/PF resin were considerably reduced from 445 s and 147.8 °C for the neat PF resin to 317 s and 127.8 °C, respectively. This was attributed to the oxidative crosslinking of catechol moieties in DCS and amino groups in PEI@G within the naturally alkaline environment of phenolic resins in addition to the high reactivity between catechol moieties and PF chains as well as between amino and PF chains. The prepared resin demonstrated a dry bonding strength of 2.56 MPa, wet bonding strength of 1.81 MPa, and debonding work of 0.714 J, exhibiting a considerable increase of 16.9 %, 52.1 %, and 95.1 %, respectively, compared with those of the PF resin. These improvements were attributed to the dense organic–inorganic hybrid crosslinking network formed in the DCS/PG/PF. Furthermore, the DCS/PG/PF resin exhibited enhanced thermal stability.

Spider silk fibers (SSF) have a hierarchical structure composed of proteins with highly repetitive sequences and biomineralization is sophisticated in hierarchical organic–inorganic constructions. By using inorganic hydroxyapatite (HAP) and organic polyvinyl alcohol (PVA) to simulate the rigid crystalline and flexible amorphous protein blocks of SSF, respectively, biomimetic mineralization is herein attempted for the large-scale preparation of SSF-like macrofibers with a hierarchical ordered structure, a superhigh tensile strength of 949 ± 38 MPa, a specific toughness of 296 ± 12 J g −1 , and a stretch ability of 80.6%. The hybrid macrofibers consist of microfibers, and their outstanding performance (e.g., extreme tolerance to temperatures ranging from −196 to 80 °C and superior ability to inhibit the transverse growth of cracks) is attributed to the hierarchical arrangement as well as the organic–inorganic integrated structure within the oriented mineralized polymer chains. The biomineralization-inspired technique provides a promising tactic that can be used to synthesize functional organic–inorganic fibers that are structurally complex and, furthermore, industrially manufacture SSF-like artificial fibers with a supertoughness.

Recently, versatile hydrogels with multifunctionality have been widely developed with emerging applications as wearable and implantable devices. In this work, we reported novel versatile hydrogels by self-catalyzing the gelation of an interpenetrating polymer network consisting of acrylic acid (AA) monomers and GA-modified collagen (GCOL) in situ decorated silver nanoparticles (AgNPs). The resultant hydrogel, namely AgNP@GCOL/PAA, has many desirable features, including good mechanical properties (such as 123 kPa, 916%, and 1961 J m−2 for the fracture stress, strain and tearing energy) that match with those of animal skin, excellent self-healing performance, favorable conductivity and strain sensitivity as a flexible biosensor, and excellent antibacterial and anti-UV properties, as well as the strong adhesiveness on skin. Moreover, AgNP@GCOL/PAA showed excellent biocompatibility via in vitro cell culture. Remarkably, AgNP@GCOL/PAA displayed superior hemostatic properties with sharply decreasing blood loss for a mouse liver incision, closely related to its strong self-adhesion which produced anchoring strength to the bleeding site and thus formed a network barrier with liver tissue. This study provides new opportunities for the facile preparation of widely used multifunctional collagen-based hydrogels based on a simple pyrogallol-Ag system.
