Lignin‐Based Vitrimer for High‐Resolution and Full‐Component Rapidly Recycled Liquid Metal Printed Circuit

Advanced Functional Materials, Journal Year: 2025, Volume and Issue: unknown

Published: April 14, 2025

Abstract Room‐temperature liquid metals (RTLMs) exhibit inherent fluidity, metallic conductivity, remarkable stability, and recyclability, which indicate significant potential for applications in improving the efficiency of electronics recycling reducing costs. However, low viscosity RTLMs their poor interfacial adhesion to substrates typically necessitate utilization intricate fabrication processes. Here, a viscosity‐tunable, photothermal repairable, full‐component recyclable eutectic gallium–indium/epoxy‐modified lignin/polyethylene glycol diacid/ethylene vitrimer (EGaIn‐LPEv) is presented printed circuits. The system displays good stability tunable at room temperature because ultra‐high reactive site content modified lignin dual dynamic bonding by introduction ethylene glycol. EGaIn‐LPEv‐based circuit exhibits high resolution full component recovery up 7.6 µm 98.3 wt.%, respectively. As principal component, not only enhances system's green credentials but also endows it with an efficient repairable capability. reconnection damaged can be achieved 15 s through 808 nm infrared activation. This study opens new avenue development manufacturing processes sustainable application advanced, high‐resolution, fully recycled electronic devices.

Reversibly Cross‐Linked Plastics Meet Carbon Fibers: Closed‐Loop Recyclable Composites with Enhanced Mechanical Strength and Stability

Advanced Functional Materials, Journal Year: 2025, Volume and Issue: unknown

Published: Feb. 24, 2025

Abstract Efficient recycling of carbon fiber‐reinforced polymer composites (CFRCs) into their original monomers and fibers (CFs) in a non‐destructive manner remains significant challenge. In this study, high‐performance, closed‐loop recyclable aromatic polyamide (APAD) plastics are synthesized via polycondensation amines aldehydes through dynamic imine bonds. Due to fully structure as well interchain hydrogen bonds π–π interactions, APAD exhibit tensile strength ≈78.3 MPa, glass transition temperature ( T g ) ≈200.4 °C, excellent chemical resistance. The can be depolymerized mixture polar organic solvents acids at ambient temperature, enabling high‐purity recovery precipitation selective solvents. Water‐resistant CF/APAD fabricated complexation with CF cloths. These mechanical properties comparable those CF/epoxy thermoset superior thermal stability. mild depolymerization conditions for enable the efficient disintegration composites. Therefore, CFs realized. recovered cloths used re‐manufacture This study presents an effective method CFRCs, offering environmental economic benefits.

Covalent Adaptable Networks Containing Nitrogen-Coordinated Boronic Ester and Imine Bonds

ACS Applied Polymer Materials, Journal Year: 2024, Volume and Issue: 6(15), P. 9008 - 9016

Published: July 31, 2024

Covalent adaptable networks (CANs) are supposed to address the reprocessing and recycling issues of epoxy resins via their reversible cross-linking structures. However, development CANs simultaneously exhibiting high mechanical strength fast-reprocessing ability is still a huge challenge. Herein, with fabricated by modifying linear polymers nitrogen-coordinated boronic ester imine bonds. Owing densities rigid network structures, obtained show breaking ∼76.0 MPa, yield stress ∼81.5 Young's modulus ∼1.67 GPa, respectively. Because fast exchange reaction bonds, as-prepared can be easily processed into desirable shapes within only 1 min at 150 °C under pressure 10 MPa. Moreover, owing this unique feature, quickly reprocessed least three times without losing original properties. Finally, prepared exhibit shape fixed ratio recovery more than ∼90% when used as shape-memory polymers. This study provides feasible solution for constructing mechanically strong thermosets ability, which will contribute next-generation sustainable resins.
