Polysiloxane Pickering emulsions are prepared based on fluorine modified SiO2 nanoparticles. A series of modified SiO2 nanoparticles with different surface wettability were prepared using anhydrous THF as the reaction solvent and different FDTS amounts. Different polysiloxane Pickering emulsions are prepared by adjusting the type and quantity of Pickering SiO2 nanoparticles.
