In this article we describe the combined use of γ‐irradiation initiated micro‐emulsion polymerization and redox interfacial‐initiated micro‐emulsion polymerization to prepare hollow polystyrene micro‐spheres with movable CdS nanoparticles inside (CdS@PSt) hybrid materials under room temperature and ambient pressure. First, mono‐dispersed CdS nanoparticles with diameters 50 nm were synthesized in inversed micro‐emulsion under γ‐irradiation. Then, CdS nanoparticles were coated with PSt via interfacial‐initiated micro‐emulsion polymerization with cumene hydroperoxide/ferrous sulfate (CHPO‐Fe 2+ ) as the redox initiation pair. The resulted CdS@PSt hybrid materials were identified by transmission electron microscopy (TEM), field emission scanning electron microscopy (FESEM), dynamic light scattering (DLS) and X‐ray powder diffraction (XRD). © 2008 Wiley Periodicals, Inc.
