Research Abstract

In the Melting dispersion method of multiple emulsion, dispersion behaviors of core and shell droplets such as leakage in the microencapsulation process were examined with hydrodynamics and interface chemistry. The suitable preparation process of microcapsules with high content and single core examined by using an equation for the dispersion behaviors was considered. Application of the equation for controlling microcapsule structure was suggested.
