摘要：

We have examined photopolymerization of highly monodisperse microdroplets of monomer solutions under UV-light radiation. Microdroplets were generated using a modified vibrating aerosol generator, and the diameter of the droplets can be tuned to any size between 5 to 100 gym. Polymer particles derived from the droplets were characterized by optical microscopy and SEM. The results show that the polymer particles, under optimum conditions, can be highly spherical and monodisperse. The diameter and morphology of resulting microspheres depend on the diameter of the monomer solution droplets, monomer concentration, photopolymerization reaction temperature, residence time, and droplet dispersion.
