In this paper we reported the fabrication of submicrometer- to micrometer-scale ferroelectric copolymer particles by a simple solution mixture method. Particle diameter could be controlled by the second solvent and/or the volume ratio of the second solvent to copolymer butanone solution. These particles were also ferroelectric and could be re-dispersed into water to form a suspension, as facilitated by the potential applications of these particles. (C) 2009 Elsevier B.V.
