Abstract
Finally, as an extension of our acoustic excitation technique, we developed a method for fabricating uniform microcapsules exhibiting controlled shell thickness. The addition of a second concentric nozzle to our system allowed us to spray a dual polymer jet. Considering the interfacial tensions and spreading coefficients of the polymer components and non-solvent phase for the resulting emulsion, we were able to identify working parameters providing complete encapsulation of one polymer in another.
