Non-isocyanate polyurethanes (NIPUs) from renewable resources have attracted wide attention because of their remarkable benefits to sustainable development and green production. In this work, a strong, self-healing, catalyst-free NIPU (ECMP) was prepared based on the hyperbranched bio-based cyclic carbonate (Ec-MTDA) synthesized through catalytic carbonization 1,8-menthane diamine (MTDA) CO2. The rigid structures ECMP enable improved mechanical properties that high tensile strength up 34.9 MPa can be achieved. Benefiting dynamic transesterification reaction between carbamate hydroxyl groups, presents favorable reprocessing properties, shape memory. Notably, 91% original recovered after self-healing behavior. addition, abundant polar groups provide excellent adhesion for with shear 7.09 MPa. This study provides promising strategy design NIPUs, which broadens applications in printing, furniture, packaging, other industries.

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.

Abstract Abnormal healing following skin injury, such as slow and scar formation, can significantly affect an individual's life. Complex treatment methods cumbersome instruments have reduced the efficacy of treating diseases. In this study, a novel biocompatible liquid metal (LM) composite wound dressing (LGPU) is designed by synthesizing polyurea polyurethane (PU) blending it with LM modified glutathione (GSH), bioactive three‐peptide compound. The effects external electrical stimulation (ES) on wound‐induced hair follicle neogenesis are explored. dressings exhibited few important properties, including conductivity, high stretchability, recyclability, and, most importantly, excellent self‐healing capacity, owing to nature fillers highly dynamic characteristics hydrogen bonds. Furthermore, combination therapy LGPU ES promoted fibroblast migration accelerated healing. wounds treated fully healed in nine days, while blank group still scabbing state. Remarkably, method activate regeneration healthy growth follicles at site which beneficial for reducing scarring. Collectively, innovative provides facile strategy accelerate achieve scar‐free repair.

This review focuses on the sintering of liquid metal particles (LMPs). Here, means partial merging or connecting (or droplets) to form a network percolated and, thus, conductive electrical pathways. LMPs are attractive materials because they can be suspended in carrier fluid create printable inks distributed an elastomer soft, stretchable composites. However, films and traces not typically as fabricated due native oxide that forms surface particles. In case composites, polymers also get between particles, making more challenging. Sintering done via variety ways, such mechanical, thermal, chemical processing. discusses mechanisms sinter these patterning techniques use sintering, unique properties sintered LMPs, their practical applications fields electronics, soft robotics, active materials.
