Abstract

Stimuli-responsive Pickering emulsion system has received considerable scientific interests for myriad applications. In this contribution, nanocomposites (PDMNC) made of Fe₃O₄ nanoparticle and poly[2-(dimethylamino)ethyl methacrylate] were prepared through a facile sonochemical in situ co-precipitation approach and were used in the preparation of Pickering emulsion system (PDMNC-PE). PDMNC-PE exhibited pH-responsive behavior and it was stable at pH ranging from 5 to 9. Upon magnetic exposure, PDMNC-PE underwent repeatable and rapid emulsification/demulsification triggered by a change in pH for at least six cycles. The stabilization/destabilization of PDMNC-PE was caused by the synergistic effect from magnetic force, surface hydrophobicity and zeta potential of PDMNC in response to pH, which resulted in the adsorption/desorption of PDMNC at the interface of the Pickering emulsions. The magnetic- and pH-reversible PDMNC-PE has a great potential for application in oil recovery.
