INVESTIGATION OF THE PRODUCTION OF TRICLOSAN/CHITOSAN NANOCAPSULES FOR FUNCTIONAL SURFACE APPLICATIONS

This study focuses on producing monodisperse nanocapsules with a triclosan/chitosan core-shell structure using the coaxial electrospray method. The coaxial electrospraying method enables the production of core/shell structured nanocapsules in a single step. The effects of flow rate, core-to-shell flow rate ratio, and needle size on the coaxial electrospray process were systematically analyzed. The resulting nanocapsule structures were characterized using scanning electron microscope (SEM), transmission electron microscope (TEM) and size measurements. The experiments demonstrated that fibrillation more likely occurred when the chitosan content was highest.
