Abstract

Abstract:

The Pickering emulsifying properties of lauric acid-modified zinc oxide nanoparticles were studied. By adjusting the amount of lauric acid, the wettability （contact angle θ） of ZnO nanoparticles were changed, and the droplet size, phase transition and stability of the Pickering emulsions stabilized by ZnO nanoparticles with different contact angles were discussed. The results indicated that by using ZnO nanoparticles that were partially hydrophilic （three-phase contact angle of 40°-60°）, the O/W Pickering emulsion thus prepared exhibited the smallest droplet size and optimal stability. Furthermore, silicone elastic microspheres with ZnO nanoparticles on the surface were prepared under the optimal conditions by Pickering emulsion polymerization, and the particle size of silicone elastic microspheres was 5-20 μm.

Key words: Pickering emulsion, Zinc oxide, lauric acid, surface modification, contact angle, emulsion stability
