Conductive and self-healing (SH) hydrogels have been receiving continuous attention, which could broaden the design of ionotronic devices for health monitoring systems soft robots with ability to repair damage autonomously. So far, three-dimensional (3D) fabrication such SH is mainly limited traditional molding/casting or extrusion-based 3D printing methods, limits formation sophisticated structures high-resolution features. Furthermore, need external stimuli (e.g., water, heat, pH change)...
Creatures in nature possess unique smart material systems that can sense environmental changes with evolved self-responsible architectures. For example, the Japetella heathi octopus exhibits a remarkable ability to change its appearance evade attention of predators. Here, we present an approach produce heathi-inspired materials thermal sensing architectures by multimaterial three-dimensional (3D) printing, where both conventional acrylic-based ultraviolet resins and reactive liquid crystals...
Abstract The creatures in nature exhibit dynamic responses to environmental stimuli through their hierarchical architectures. Benefiting from gradient porous structures, Delosperma nakurense opens its protective valves of the seed capsules when hydrated with liquid water, increasing likelihood that seeds are dispersed under conditions favorable germination. Here, a versatile 4D printing technology, namely crystal templating‐assisted vat photopolymerization (LCT‐VPP), which can fabricate...
Thiol-acrylate photoresin containing dynamic disulfide bonds undergoes wavelength-selective photopolymerization under green vs. UV light to produce a degradable step-growth network permanent chain-growth network.

Abstract Conventional crosslinked photopolymers possess permanent network structures, which cannot be remolded/recycled and generally discarded as waste after use. Research has begun to incorporate dynamic bonds into make them reprocessable/recyclable, however, previous studies typically require tedious pre‐syntheses obtain photoreactive building blocks that contain desired linkages/functionalities. In this study , we report a simple, one‐step, scalable synthesis of chemically recyclable...
Abstract The emerging Internet of Things (IoTs) invokes increasing security demands that require robust encryption or anti‐counterfeiting technologies. Albeit being acknowledged as efficacious solutions in processing elaborate graphical information via multiple degrees freedom, optical data and techniques are typically inept delivering satisfactory performance without compromising the desired ease‐of‐processibility compatibility, thus leading to exploration novel materials devices competent....
The cross-linked structures of most commodity polyurethanes (PUs) hinder their recycling by common mechanical/chemical approaches. Catalyzed dynamic carbamate exchange emerges as a promising PU strategy, which converts traditional static thermosets into reprocessable covalent adaptable networks (CANs). However, this approach has been limited to thermoset-to-thermoset reprocessing CANs, accompanied well-preserved network and extremely high viscosities, pose challenges processing certain...

In this work, we developed a photoalignment and photopatterning method to fabricate polymer-stabilized-liquid-crystals (PSLCs) for optical data encryption anti-counterfeiting purposes. The PSLCs possess both implicit patterns as well explicit geometries, could serve with improved environmental robustness thermal stability after post-extraction process, can be directly bonded onto various substrates. Based on this, prototyped proof-of-concept demonstrations using either one single...
