“…Okubo et al have reported that anisotropic particles can be synthesized by dispersion polymerization or seed dispersion polymerization. 11 Weitz et al also reported the synthesis of dumbbell-type polymer particles by seed polymerization. 12 However, the preparation of nanostructured polymer particles requires highly sophisticated synthetic techniques.…”

In this account, we review recent developments in the preparation of various functional and nanostructured polymer particles by precipitation-based methods. First, we present an overview of recent polymer particle preparation methods including methods for precipitation-based particle preparation. Next, we introduce the self-organized precipitation and its advantages. We discuss the morphological control of polymer particles based on the types of polymer materials used for particle preparation. We also introduce the preparation of organicinorganic composite particles. Finally, we discuss the future outlook of nanostructured polymer particles.

“…It can be seen that hamburger-like PS/PEHMA/decane composite particles were prepared by SDP (Fig. 2a) in which a disc-like PS was sandwiched in between two pieces of PEHMA/decane breads as reported by Okubo et al [21,22]. Disc-like PS particles were obtained after the extraction of PEHMA and decane with 1-butanol from hamburger-like composite particles (Fig.…”

“…Recently, Okubo et al used SDP in the presence of organic solvent droplets and prepared nonspherical particles [20][21][22]. In this technique, most of the organic solvent was absorbed by the second polymer domains of the composite particles.…”

“…In the case of "disc-like" PS particles, the SDP of 2-ethylhexyl methacrylate (EHMA) was carried out with PS seed particles in the presence of saturated hydrocarbon droplets. They suggested that the absorbed amount of the solvent by seed polymer and the second polymer and the distribution of the solvent between them affect the rates of second polymer/solvent domains coalescence and Ostwald ripening between the domains, resulting in various nonspherical particles [21,22].…”

“…After the evaporation of the solvent and volume reduction in the composite particles, various nonspherical shapes were produced. By utilizing this technique, they prepared "golf-balllike" poly(methyl methacrylate) (PMMA) particles [20] and "disc-like" polystyrene (PS) particles [21,22]. In the case of "disc-like" PS particles, the SDP of 2-ethylhexyl methacrylate (EHMA) was carried out with PS seed particles in the presence of saturated hydrocarbon droplets.…”

In this study, the preparation of micron-sized polymer particles having a novel and unique nonspherical shape which we called almond-shell-like by dual-seeded dispersion polymerization (DSDP) of 2-ethylhexyl methacrylate (EHMA) with polystyrene (PS) and poly(methyl methacrylate) (PMMA) seed particles in the presence of decane droplets and evaporation of decane after the polymerization was discussed. The experimental results showed that mushroomlike morphology which is a precursor of the almond-shell-like shape was obtained from DSDP of EHMA. It was found that with changing the PS/PMMA seed particles' weight ratio, the size of the dents on the surface of the particles can be controlled. Furthermore, it was observed that various nonspherical particles can be produced using different methacrylic seed particles and initiators.
