Switchable deep eutectic solvents as efficient and sustainable recycling media for carbon fiber reinforced polymer composite waste

Supercritical CO2/Deep Eutectic Solvent Biphasic System as a New Green and Sustainable Solvent System for Different Applications: Insights from Molecular Dynamics Simulations

“…Many attempts have been made to resolve this problem. Hydrophobic DESs were first introduced in 2015 by Kroon et al Continued research works were subsequently published and reviewed. − However, DESs with switchable hydrophilic/hydrophobic nature are more desirable. − Recently, Liu et al developed a CO 2 switchable deep eutectic solvent for oil recovery. They found that the hydrophobicity of DES can be modified by CO 2 .…”

Recycling and repurposing of waste carbon nanofiber polymers: a critical review

“…66 Recently, the emergence of novel green solvents, represented by ionic liquids and low eutectic solvents, has reinvigorated the prospects for this method. Liu et al 65 pioneered using hydrophobic DES (deep eutectic solvents) as a recyclant (Fig. 5b).…”

Recycling and recovery of fiber-reinforced polymer composites for end-of-life wind turbine blade management

“…In addition, the solvolysis recycling process is relatively complex and expensive, limiting its application on a large-scale. Therefore, much attention has been paid to the development of efficient, green and closedloop solvolysis processes for the recycling of the composites in end-of-life WTBs, [78][79][80][81][82] mostly focusing on the use of green or recyclable solvents, efficient and low-cost catalysts, and mild reaction conditions. Recently, the journal Nature reported a metal-catalyzed protocol for recovering the polymer building block bisphenol A and intact fibers from epoxy resin composites.…”
