CO2-responsive Pickering emulsions stabilized by in-situ generated ionic liquids and silica nanoparticles

Stimuli-responsive Pickering emulsions have attracted increasing interest because of the advantages of applications in numerous industrial processes. In this work, Pickering emulsions have been obtained by using negatively charged silica nanoparticles in association with very small amount of CO2-responsive ionic liquids as stabilizer. Ionic liquids N-alkylimidazole bicarbonates ([Cnim]+HCO3−, n = 6, 8, 10, 12, 14) are in-situ generated by...
