Polyetheramine-modified polyurethane sponge for interfacial demulsification-enhanced coalescence separation of O/W emulsions.
A material-preparation and separation strategy integrating interfacial demulsification with coalescence separation was proposed for efficient O/W emulsion treatment. Demulsification-functionalized coalescence materials (PEA-PDA@PU) were prepared by depositing a polydopamine (PDA) interlayer on polyurethane (PU) sponges...
