In the present work superamphiphilic porous hydrogel membranes are prepared for efficient oil-water separation. A monolith, highly porous, and mechanically robust scaffold is synthesized for the adsorption of pollutants from both aqueous and non-aqueous media with facile separation and regeneration. Methylcellulose-tannic acid complex particles were prepared and systematically decorated on the surface of interpenetrating polymer network scaffold via Pickering emulsion. The hydroxyl and carboxyl groups of tannic acid, alginate, and polyacrylic acid created hydrogen bonding, electrostatic interaction, acid-base interaction, and π-π stacking. Adsorption/absorption kinetics and mechanisms are examined under aqueous and non-aqueous environment. The effects of various processing parameters for Pickering emulsion and scaffolding on dual pore membrane system are also examined. The overall performance is evaluated in oil-water separation. |
