Abstract
To coat microsized poly(methyl methacrylate) (PMMA) particles of uniform size and density on poly(ethylene terephthalate) (PET) films, we introduce an electrospraying technique that uses a target electrode applied with an ac electric field. Using the apparatus and various material properties, we could achieve good collection and a uniform size distribution of hemispherical droplets on the PET film. The optical properties, transmittance, and light diffusivity of the films electrosprayed with the PMMA were characterized and the sprayed particles appear to act as a good optical diffuser, like microlenses.
