Dual (magnetic and pH) stimuli-reversible Pickering emulsions based on poly(2-(dimethylamino)ethyl methacrylate)-bonded Fe3O4 nanocomposites for oil recovery application
Stimuli-responsive Pickering emulsion system has received considerable scientific interests for myriad applications. In this contribution, nanocomposites (PDMNC) made of Fe3O4 nanoparticle and poly2-(dimethylamino) ethyl methacrylate] were prepared through a facile sonochemical in situ co-precipitat...

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.
