The urgent need to mitigate climate change, as emphasized by the United Nations Sustainable Development Goal 13, has driven research into developing environmentally friendly solvents for various industrial applications. Deep Eutectic Solvents (DESs) have emerged as green alternatives to conventional chemical methods, offering advantages such as low toxicity, biodegradability, and energy-efficient processing. However, the successful implementation of DES-based technologies requires robust separation methods for recovering these solvents after use. This challenge is compounded by the solvent's potential to degrade many polymeric materials, necessitating the development of solvent-resistant membranes. As shown in Figure 1, our research employs a comprehensive approach to developing DES-resistant membranes, beginning with theoretical polymer screening using Relative Energy Difference (RED) calculations, followed by experimental validation to ensure solvent resistance. Polyvinylidene Fluoride (PVDF) membranes, selected through this screening process, were subjected to adsorption experiments to evaluate DES-membrane interactions. The adsorption kinetics were modeled using pseudo-first-order and pseudo-second-order equations, while isotherm behavior was analyzed through Langmuir and Freundlich models to elucidate equilibrium dynamics. Preliminary findings underscore the importance of polymer compatibility with DESs in preserving membrane integrity and performance. The adsorption studies aim to identify optimal membrane conditions for efficient DES recovery without compromising membrane durability. This research contributes to the broader effort of reducing CO₂ emissions by advancing DES-based technologies for sustainable industrial processes.
