摘要

Functionalized PS/SiO2 composite nanoparticles bearing sulfonic groups on the surface were successfully synthesized via emulsion copolymerization using a polymerizable emulsifier α olefin solfonate (AOS). As demonstrated by transmission electron microscopy and atomic force microscopy

well-defined core-shell PS/SiO2 composite nanoparticles with a diameter of 50 nm were obtained. Sulfonic groups introduced onto the surface of the composite nanoparticles were quantified by FTIR

and can be controlled to some extent via a two-stage procedure.
