Lignin‐Based Encapsulation of Liquid Metal Particles for Flexible and High‐Efficiently Recyclable Electronics

Advanced Functional Materials, Journal Year: 2023, Volume and Issue: 34(7)

Published: Oct. 29, 2023

Abstract Room‐temperature liquid metals (RTLMs) have excellent shape reconfiguration capabilities, which make them ideal for flexible electrodes, sensors, and energy devices. However, due to the high surface tension weak adhesion of RTLM, types printing substrates, patterning, recovery processes are limited. It is essential develop advanced encapsulation techniques patterning RTLMs. Lignin has great potential promotion as nanodispersants nanocarriers because its abundant hydroxyl groups good self‐assembly properties. In this work, a green facile method using industrial lignin reported stable, uniform, reproducible eutectic gallium–indium (EGaIn). Lignin‐encapsulated EGaIn particles exhibit stability can be patterned on various substrates with simple ballpoint pen. The electrical resistance conductive tracks shows little change under bending twisting (720°) conditions. More importantly, lignin‐encapsulated system easily dissolved regenerated, also supported by molecular dynamics simulations density functional theory calculations. 96.9% recovered from system. These characteristics it very environmentally friendly throughout preparation process find applications in transient circuits, many other areas.

Reconstruction of Cellulose Intermolecular Interactions from Hydrogen Bonds to Dynamic Covalent Networks Enables a Thermo-processable Cellulosic Plastic with Tunable Strength and Toughness

ACS Nano, Journal Year: 2023, Volume and Issue: 17(21), P. 21420 - 21431

Published: Nov. 3, 2023

Its excellent renewability and biodegradability make cellulose an attractive resource to prepare fossil-based plastic alternatives. However, itself exhibits strong intermolecular hydrogen bond (H-bond) interactions, significantly restricting the mobility of chains, thus leading poor thermo-processing performance. Here, we reconstructed interactions chains via replacing original H-bonds with dynamic covalent bonds. By this, can be easily thermo-processed into a cellulosic under mild conditions (70 °C). Through adjusting chemical structure networks, shows tunable mechanical strength (3.0–33.5 MPa) toughness (43–321 kJ m–2). The also resistance water, organic solvent, acid solution, alkali high temperature (>400 Moreover, it owns good biological degradability recyclability. This work provides effective method develop high-performance plastics for substitution.
