Abstract Gradient matters with hierarchical structures endow the natural world excellent integrity and diversity. Currently, direct ink writing 3D printing is attracting tremendous interest, has been used to explore fabrication of 1D 2D by adjusting diameter, spacing, angle between filaments. However, it difficult generate complex gradient owing inherent limitations existing methods in terms available dimension, resolution, shape fidelity. Here, we report a filament diameter-adjustable strategy that enables conventional extrusion printers produce 1D, 2D, tunable heterogeneous continuously varying volume deposited on trajectory. In detail, develop diameter-programmable filaments customizing velocity height. To achieve high fidelity, specially add supporting layers at needed locations. Finally, showcase multi-disciplinary applications our creating horizontal, radial, axial structures, letter-embedded metastructures, tissue-mimicking scaffolds, flexible electronics, time-driven devices. By showing potential this strategy, anticipate could be easily extended variety filament-based additive manufacturing technologies facilitate development functionally graded structures.

Natural materials with highly oriented heterogeneous structures are often lightweight but strong, stiff tough and durable. Such an integration of diverse incompatible mechanical properties is desired for man-made materials, especially weak hydrogels which lack high-precision structural design. Herein, we demonstrate the fabrication hierarchically aligned consisting a compactly crosslinked sheath porous core alignments nanofibrils at multi-scales by sequential self-assembly assisted salting out method. The produced hydrogel offers ultrahigh among reported hydrogels, elastomers natural including toughness 1031 MJ · m-3, strength 55.3 MPa, strain 3300%, stiffness 6.8 fracture energy 552.7 kJ m-2 fatigue threshold 40.9 m-2. Furthermore, such strong facilely achieves stable regeneration rapid adhesion owing to crystallized network structure. regenerated specimen presents reinforced strength, resistance over 10 cycles. This work provides simple method produce bioinspired heterostructures combinational real applications. have favorable properties, challenging replicate in artificial materials. Here, authors report development strength.

Abstract Biological materials, although composed of meager minerals and biopolymers, often exhibit amazing mechanical properties far beyond their components due to hierarchically ordered structures. Understanding structure–properties relationships replicating them into artificial materials would boost the development bulk structural nanocomposites. Layered microstructure widely exists in biological serving as fundamental structure nanosheet‐based nacres nanofiber‐based Bouligand tissues, implying superior properties. High‐efficient scalable fabrication bioinspired nanocomposites with precise layered is therefore important yet remains difficult. Here, one straightforward bottom‐up film‐to‐bulk assembly strategy focused for fabricating The inherently offers a methodology construction form, availability large sizes complex shapes, possibility design multiscale interfaces, feasibility manipulation diverse heterogeneities. Not limited discussing what has been achieved by using current strategy, it also envisioned how promote such an better benefit Compared other strategies, highlighted provides great opportunities creating on demand.

Multifunctional fibers with high mechanical strength enable advanced applications of smart textiles, robotics, and biomedicine. Herein, we reported a one-step degumming method to fabricate strong, stiff, humidity-responsive cellulosic from abundant natural grass. The facile process involves partially removing lignin hemicellulose functioning as glue in grass, which leads the separation vessels, parenchymal cells, fibers, where are manufactured at kilogram scale. resulting show dense unidirectional fibril structure both micro- nano-scales, demonstrate tensile ∼0.9 GPa Young's modulus 72 GPa, being 13- 14-times higher than original Inspired by stretchable plant tendrils, developed actuator engineering into spring-like structures, presenting superior response rate lifting capability. These strong can be large scale low cost, representing promising fiber material derived renewable sustainable biomass.
