Eutectic Molecular Liquids Based on Hydrogen Bonding and π–π Interaction for Exfoliating Two-dimensional Materials and Recycling Polymers

Graphical Eutectic molecular liquids based on hydrogen bonding and π–π interaction were formed and used for exfoliating two-dimensional materials and recycling polymers. Eutectic molecular liquids (EMLs) based on hydrogen-bonding interaction and π–π stacking were prepared. We found that the thermodynamic properties like initial decomposition temperature and glass transition temperature of EMLs are mainly dominated by the hydrogen bond donor, which is beneficial for designing and preparing new EMLs. These new liquid systems could be applied in the field of environmental and material science.
