Abstract Biomass‐encapsulated liquid metals (LMs) composite gels have aroused tremendous attention as epidermal smart materials due to their biocompatibility and sustainability. However, they can still not simultaneously possess toughness, adhesion, recoverability. In this work, the tough, sticky, recyclable protein‐encapsulated LMs organogels (GLM x ) are fabricated through micro‐interfacial stabilization of by lignin following preparation food‐making inspired gels. With help modification, micro‐drops demonstrated uniform dispersion in protein matrix, well dense non‐covalent interactions (e.g., H─bond hydrophobic interaction) with amino acid residues peptide chains, which endowed GLM high conductivity (≈5.4 S m −1 ), toughness (≈738.2 kJ −3 self‐adhesiveness (a maximal lap‐shear strength ≈58.3 kPa), By tightly adhering onto human skin, act sensors detect drastic joint bending) subtle body movements swallowing) even recognize handwriting speaking real‐time. Moreover, also harvest solar energy convert it into heat electricity, is promising self‐powered intelligent devices. Thus, work paves a facile way prepare protein/LMs that suitable for multiple applications like healthcare, human‐robot interactions, conversion.

Lignin, the most abundant aromatic biomaterial on Earth, is widely available as a byproduct of papermaking and biorefinery industries could serve green filler for rubber. However, preparing high-performance multifunctional rubber/lignin composites remains challenging due to inhomogeneous dispersion lignin in rubber matrix poor lignin–rubber interfacial adhesion. In this article, facile modification approach was proposed. Namely, we used deep eutectic solvent (DES), composed choline chloride ZnCl2, simultaneously improve enhance rubber–lignin interaction by constructing metal–ligand coordination bonds at interface. The resulting elastomer exhibited significantly enhanced mechanical oil-resistance properties. Moreover, introduction DES photothermal effect composite. This scalable environmentally friendly strategy anticipated provide novel inspiration large-scale utilization elastomers.

Dynamic Covalent Oleogel with Mechanical Force‐Induced Reversible Phase Transition for Self‐Adaptive Lubrication

Advanced Functional Materials, Год журнала: 2025, Номер unknown

Опубликована: Фев. 9, 2025

Abstract Substantial progress has been made in stimulus‐responsive and performance‐tunable hydrogels, yet endowing organogels with dynamic adaptive properties remains challenging. Especially, the development of functional oleogel materials is further constrained by weak interactions between oil gel network, along high viscosity oil. Herein, state self‐adaptability oleogels enabled constructing mechanical responsive covalent networks via ring‐opening polymerization thioctic acid (TA). Mechanically breaking rebuilding disulfide bonds endow force‐induced reversible phase transition poly(TA) oleogels. Mechanical bond breakage disrupts transforming into a sol state. Once force removed, rapid bonding sulfur radicals rebuilds network. Furthermore, this highly generalizable strategy potential as self‐adaptive lubricant. Self‐adaptive can exist or that adapts to whether machine running stopped. Systematic tribological tests confirm excellent lubricating their outstanding performance stability adapting changing friction conditions. This provides insights for developing properties, well new smart materials.

Solvent-free processing of lignin into robust room temperature phosphorescent materials

Nature Communications, Год журнала: 2025, Номер 16(1)

Опубликована: Март 12, 2025

Abstract Producing room temperature phosphorescent (RTP) materials from biomass resources using a solvent free method is essential but hard to achieve. Here, we discovered that lignin dissolved well in the liquid monomer, 2-hydroxyethyl acrylate (HEA), due extensive hydrogen bonding and non-bonding interactions between HEA. Motivated by this discovery, developed system consisting of HEA urethane dimethacrylate (UDMA) for converting into RTP materials. With design, generated radicals upon UV irradiation, which initiated polymerization (as monomer) UDMA crosslinker). The as-obtained polymer network rigidifies activates humidity/water-resistant with lifetime 202.9 ms. Moreover, afterglow color was successfully tuned red after loading RhB via energy transfer (TS-FRET). Using these properties, as-developed material used as photocured multiple-emission inks, luminescent coatings smart anti-counterfeiting logo medicine bottle.
