Abstract
- Abstract: One mild multiple emulsions was used for the fabrication of hollow polystyrene (PS) spheres. Polystyrene was dissolved in a volatile organic solvent to form the O phase, then an aqueous phase containing a surfactant was transferred into above phase to form an oil-in-water (Win/O) emulsion, followed by addition of Win/O emulsion in the external Wout phase, and solvent evaporation. Final product with diameter of 150μm, surface roughness of 30nm, and sphericity of 98.0% was obtained. The possible influences on the formation of PS hollow sphere were also discussed.
