| Abstract: | This paper described the fabrication of CdS-nanoparticle/polystyrene latexes through the combined use of surface-initiated atom transfer radical polymerization(ATRP) and gas/solid reaction. The epoxy groups modified polystyrene(PS) latexes were grafted with α-Br groups easily through the reaction between epoxy groups and BMPA in water. And then, Cd(MA)2 was polymerized via surface-initiated ATRP on the surface of α-Br groups modified PS spheres, CdS nanoparticles were formed in situ by bubbling H2S gas. The resulted CdS-nanoparticle/PS latexes take on strawberry-like shapes and presented a strong fluorescence property. |
