Abstract A light responsive toluene-in-water novel emulsion stabilized by positively charged TiO2 nanoparticles combined with similarly charged dye molecules rhodamine B (RhB) at low concentrations is prepared. The novel emulsion can be destabilized under UV irradiation because of the degradation of RhB molecules aroused by anatase TiO2 nanoparticles. The stabilization mechanism of light responsive novel emulsions was proposed. Further, the novel emulsions can be turned into a magnetic responsive Pickering emulsion by adding Fe3O4 nanoparticles, which can be driven close to each other by magnetic field without demulsification. This work provides a deep understanding for the regulation mechanism of novel emulsions upon UV irrigation and opens the new way for the transformation from novel emulsions to Pickering emulsions.
