Abstract

Magnetic-responsive switchable emulsions, which are stabilized by 3-aminopropyltriethoxy silane coated nanoparticles, have been developed in this study. The emulsions show excellent stability for dozens of days and more importantly perform complete demulsification on demand in several minutes. This study provides a facile and possible manipulation strategy to re-disperse the components, re-produce the stable emulsions, and re-trigger the demulsification performance without long-lasting effects.
