Summary: A cost-effective and sustainable method was developed to produce lignin-based cryogels with a mechanically robust 3D interconnected structure. A ChCl-LA-based DES was used as a cosolvent to promote the synthesis of lignin-resorcinol-formaldehyde (LRF) gels. The addition of MOF during the sol-gel process significantly accelerated the gelation of lignin. The resulting LRF carbon cryogels exhibited excellent performance in energy storage devices.

Summary: High-entropy-oxides (HEOs) have unique structures and fascinating physicochemical properties, but constructing various nanostructured HEOs under high temperature synthetic conditions is challenging. A strategy using deep eutectic solvent (DES) as a solvent and carbon source was proposed, successfully synthesizing HEOs with 2D nanonets and 1D nanowires. These HEOs have uniformly dispersed metal elements, large specific surface areas, and a pure single-phase structure, providing new opportunities for stable HEOs as highly active functional materials.

Summary: This study prepared chitosan (CS) composite films by selectively dissolving lignin using deep eutectic solvents (DES), and investigated the toughening effect of DES/lignin on CS film substrate and its mechanism. The addition of DES/lignin effectively improved the plasticity of CS film, resulting in a maximum elongation at break of 62.6% for the plasticized film, which was 12.5 times that of the CS film. FTIR and NMR analyses demonstrated that the molecules in the DES/lignin complex interacted with CS, breaking the hydrogen bonds between CS molecules, and then recombined with CS molecules via hydrogen bonding. This study shows the potential of DES/regenerated lignin in improving the toughness of CS films and provides insights for the modification of plasticity in CS films.

Summary: The interactions between three deep eutectic solvents (DES) and cellulose-hemicellulose and cellulose-lignin hybrid systems were studied using a simulated computational approach. DES pretreatment can disrupt the original hydrogen bonding network structure among the lignocellulosic components and reconstruct the new DES-lignocellulosic hydrogen bonding network structure. ChCl-U exhibited the strongest effect on the hybrid systems, removing 78.3% of the hydrogen bonds between cellulose-4-O-methyl Gluconic acid xylan (cellulose-Gxyl) and 68.4% of the hydrogen bonds between cellulose-Veratrylglycerol-b-guaiacyl ether (cellulose-VG), respectively. The addition of appropriate water (DES:H2O = 1:5) and DES formed a new DES-water hydrogen bonding network structure that facilitated the interaction with lignocellulose.

Summary: In this study, switchable ionic liquids were synthesized and screened to improve the polarity and recyclability of deep eutectic solvents. By coupling with hydrogen-bond donors, a switchable-DES system with modified properties, such as viscosity, conductivity, and pH, was formed, leading to enhanced solubility of lignin compounds and improved molecular weight and uniformity. This proposed system has potential applications in the fractionation of lignin compounds and downstream industrial processes.

Summary: This study introduces a method to develop a recyclable CFRP based on epoxy vitrimer, achieving high tensile strength CFRP through the design of a self-catalytic epoxy prepolymer and catalyst-free epoxy vitrimer preparation. The matrix resin of the resulting CFRP can be efficiently degraded in pure water at high temperatures due to the built-in tertiary amines catalyzing hydrolysis of the ester bonds in the crosslinked network.

Summary: CFRPs, consisting of carbon fibers and crosslinked polymers, are essential in various applications due to their high specific strength. However, the irreversible nature of crosslinked polymers leads to difficulties in repair and recycling, resulting in environmental burdens. Chemical recycling is seen as a promising method to recover valuable components from CFRP waste, but challenges still exist.

Summary: High performance sacrificial tooling for fabricating fiber-reinforced hollow composites is successfully developed using photocuring 3D printing technology. UV-curable resins containing soluble and hydrolysable acetal acrylate cross-linker and hydrophilic 4-acryloylmorpholine monomer are used to achieve seamless internal finish. The content of cross-linker has a significant impact on printing speed, while the widely adopted UV post-curing method has negligible effect on improving thermal-mechanical properties. Printed sacrificial tooling, after thermal post-treatment, exhibits excellent thermal stability and enables fabrication of carbon fiber-reinforced hollow composites with complex geometry, showing high tensile strength and elastic modulus.
