Summary: A critical factor in achieving tunability in DESs is the variation of HBAs and HBDs. Choline fluoride-based DESs, such as EthalineF, were synthesized and characterized for the first time. Various spectroscopic techniques were used to study EthalineF, and measurements of polarity, density, viscosity, and conductivity were collected. The results showed that EthalineF has a larger solvodynamic radius compared to Ethaline, explaining the lower conductivity despite higher fluidity and solvation dynamics.

Summary: Material modification with low surface energy can achieve lower surface free energy on micro-and nano-rough structures, which is crucial for developing superhydrophobic surfaces. In this study, attapulgite (APT) was modified with alkylamine, alkylammonium salt, and stearic acid, and the interaction between low surface materials and attapulgite was explained. The results showed that the hydrophobicity of APT was significantly modified by the modifiers, and the surface free energy of the composites first decreased and then increased with increasing molecular number of low surface energy monomers.
