Droplet formation disperse morphology

The formation of microcapsules is greatly affected by the surfactant, which influences not only the mean diameter but also the stability of the dispersion. The surfactants used in the system have two roles, the first one to reduce the interfacial tension between oil and aqueous phases allowing formation of smaller microcapsules and the other one to prevent coalescence by its adsorption on the oil-water interface and therefore by forming a layer around the oil droplets. The synthesis of a core/ shell particle or other possible morphologies is mainly governed by the kinetic factors and thermodynamic factors.
