Abstract

Polymer microparticles that have pollen-like surface structures can be prepared by the evaporation of an oil-in-water emulsion. Here, polystyrene, polysulfone and PMMA was dissolved in ethyl acetate (the oil phase) and mixtures of those were emulgated in aqueous solutions of various emilsiers. The polymer particles show surface structures, and we found that polysulfone makes hemispherical protrusions in various mixtures with polystyrene or PMMA. [DOI: 10.1380/ejssnt.2015.204]
