Abstract Current treatments for chronic diabetic wounds remain unsatisfactory due to the lack of ideal wound dressings that can integrate matching mechanical strength, fast self‐healability, facile dressing change, and multiple therapeutic effects into one system. In this work, benefiting from catechol groups effect epigallocatechin‐3‐gallate (EGCG, green tea derivative), a smart hydrogel be conveniently obtained through copolymerization complex formed by EGCG 3‐acrylamido phenylboronic acid...
Poly(urea-urethane) thermosets containing the 1-tert-butylethylurea (TBEU) structure feature a reversible dissociation/association process of their covalent linkages under mild conditions. Unlike conventional thermosets, TBEU-based poly(urea-urethane) maintain malleability after curing. Under high temperature (100 °C) and applied pressure (300 kPa), ground TBEU thermoset powder can be remolded to bulk 20 min. As service our authors readers, this journal provides supporting information...
Encapsulation of small-molecule drugs in hydrophobic polymers or amphiphilic copolymers has been extensively used for preparing polymeric nanoparticles (NPs).

Abstract 4D printing has attracted tremendous interest because of its potential applications in smart devices, biomedical and tissue engineering. However, conventional shape memory polymers suffer from the single permanent recovery direction, flexibility is significantly limited. Besides, cross‐linked networks photocuring 3D‐printed objects cannot be reprocessed or repaired. To address these issues, dynamic thiocarbamate bonds are introduced into photocurable methacrylate to prepare...
Development of hydrogel-based flexible electronics with robust elasticity, low hysteresis, and excellent durability is still challenging.

Abstract Infrared transmitting materials (IRTMs) are prone to mechanical and corrosion damage during long‐time exposure harsh outside environments. However, conventional IRTMs frequently lack self‐repairability that limit their lifespan. To address the limitation, thioctic acid‐based epoxy resins (TAEs) developed from natural acid commercial monomers. The double ring‐opening polymerization (ROP) reactions of groups result in dual dynamic covalent bonds with varying bond energies containing...
