Various methods of aerosol encapsulation were studied 1 liquid phase microencapsulation, 2 condensation, and 3 coagulation. Aerosol encapsulation by condensation, using the core particles or droplets as condensation nuclei, proved to be a generally successful technique. Coagulation with inertial forces, using simple low-powered devices, showed little promise as a practical aerosol encapsulation method. Coagulation with electrostatic charging of the particles was only partially successful in solid on liquid and liquid on liquid systems, but worked quite well in encapsulating solid cores with liquid films. Liquid phase microencapsulation was quite successful, where applicable. A number of liquid cores were successfully polyersed.
