Summary: The study demonstrates the potential of separation membranes with switchable wettability in efficiently treating both oil-in-water and water-in-oil emulsions. By using a simple co-deposition method of tannic acid and diethylenetriamine, commercial polypropylene membranes are endowed with switchable surface wettability that can cyclically translate between hydrophilicity and hydrophobicity through water/ethanol treatments without losing surface wettability. Density functional theory simulations and UV-vis spectra analysis were used to illustrate the chemical mechanism behind this hydrophilicity-hydrophobicity translation.

Summary: This research presents a green development strategy for stabilizing O/W Pickering emulsions using enzymatically prepared nanocellulose (ENC). ENC has low Zeta potential and oil/water interfacial tension, facilitating the formation of stable Pickering emulsions. The study investigates the emulsification characteristics of ENC and establishes the interfacial adsorption behavior and concentration-dependent phase behavior of ENC-stabilized Pickering emulsions. Due to strong particle-particle and interface-particle interactions dominated by van der Waals forces and hydrogen bonding, ENC-stabilized Pickering emulsions exhibit excellent stability under different conditions.
