Here, we present the synthesis and characterization of statistical block copolymers containing α-lipoic acid (LA) using reversible addition-fragmentation chain-transfer (RAFT) polymerization. LA, a readily available nutritional supplement, undergoes efficient radical ring-opening copolymerization with vinyl monomers in controlled manner predictable molecular weights low molar-mass dispersities. Because lipoic diads resulting include disulfide bonds, these materials efficiently rapidly degrade when exposed to mild reducing agents such as tris(2-carboxyethyl)phosphine (Mn = 56 → 3.6 kg mol-1). This scalable versatile polymerization method affords facile way synthesize degradable polymers architectures, weights, dispersities from acid, commercially renewable monomer.

Abstract Ubiquitous anti‐counterfeiting materials with a rapidly rising annual consumption (over 10 m 2 ) can pose serious environmental burden. Biobased cellulosic birefringence offer attractive sustainable alternatives, but their scalable solvent‐free processing remain challenging. Here, dynamic chemical modification strategy is proposed for multi‐modal melt‐processing of birefringent eco‐friendly anti‐counterfeiting. Relying on the thermal‐activated covalent‐locking spatial topological structure preferred oriented cellulose, balances contradiction between strong confinement long‐range ordered structures and molecular motility required entropically‐driven reconstruction. Equipped customizable forms including mold‐pressing, spinning, direct‐ink‐writing, blade‐coating, exhibit wide color gamut, self‐healing efficiency (94.5%), recyclability, biodegradability. Moreover, diversified flexible elements facilitate fabrication compatibility universal techniques, thereby enabling versatile programmable The expected to provide references cellulose promote innovation in industry.

One-step preparation of supramolecular eutectogels (SEGs) with water resistance, transparency, underwater self-healing, self-adhesion, and full recyclability using a simple green process is intriguing but also challenging. Here, novel SEG prepared by in situ ring-opening polymerization thioctic acid (TA) polymerizable hydrophobic deep eutectic solvent (DES). Further depolymerization poly(TA) achieved synergistic interaction between the monomer DES components, resulting exhibiting highly optical extreme stretchability, recyclability. Moreover, multiple dynamic interactions enable self-healing self-adhesive processes to be easily realized even underwater. Given these comprehensive capabilities, SEGs are used as external encapsulation layers for liquid metals prepare stretchable composite wires electromyographic signal monitoring. The methodology provides new route recyclable integrated electronic components adhesives.

ABSTRACT Epoxy vitrimers have aroused increasing research attention owing to their stable physicochemical properties, recyclability, and reprocessability, they even achieve rapid self‐healing by the design of multiple dynamic covalent. However, based on requirement optimized curing process, cure kinetics epoxy vitrimer with flexibility is overtly insufficient, compared single vitrimers. Herein, an amine agent imine group (DN) disulfide β ‐hydroxyl ester groups (EP) were synthesized, respectively, thermoset was fabricated from either diglycidyl ether bisphenol A (E51) or EP cured DN. The comparison E51/DN EP/DN crosslinked network kinetics, mechanical performance investigated in detail. activation energy ( E a ) reaction for E51D 0.25 low at 31.79 kJ/mol, while EPD had higher 58.81 kJ/mol due complex reactions. Especially, when conversion up 80%, showed sharp increment combined effect groups. In terms performance, (E51D ), flexibility, self‐healing, recyclability all improved through introduction triple bonds.
