Pickering Emulsion Stabilized by Commercial Titanium Dioxide Nanoparticles in the Form of Rutile and Anatase
- 4 Downloads
The possibility of obtaining direct Pickering emulsions by means of self-organization on the oil/water interface of commercial titanium dioxide by the structure modification of rutile and anatase is studied. The stability of emulsion to coalescence is estimated microscopically. The surface properties of hydrophilic anatase nanoparticles are investigated to develop a way to partially hydrophobize their surface with molecules of n-octadecylphosphonic acid. The conditions of modifying titanium dioxide nanoparticles are chosen for the formation of stable Pickering emulsion.
