Preparation of hollow polymer particles with a single hole in the shell by SaPSeP.
The influence of sodium dodecyl sulfate (SDS) on the shell formation of hollow polymer particles prepared by the SaPSeP method, which was proposed by the authors for the preparation of micrometer-sized hollow polymer particles, was investigated. A single hole was observed in the shell of the hollow particles prepared by seeded polymerization of micrometer-sized, monodisperse divinylbenzene/p-xylene droplets in aqueous medium in the presence of SDS at concentrations above 43.3 mM, which were prepared by the dynamic swelling method. The fraction of the hollow particles having a single hole in the shell and the area of the hole increased with the SDS concentration.
