摘要

This article presents a facile approach to preparation of polystyrene/silver (PS/Ag) asymmetric hybrid particles. In this method, polystyrene/polyglycidyl methacrylate (PS/PGMA) Janus particles were synthesized via internal phase separation triggered by evaporation of dichloromethane (DCM) from PS/PGMA/DCM-in water emulsion droplets. Then, the Janus particles were aminated and sequentially carboxylated to obtain PS/PGMA-NH₂ and PS/PGMA-COOH particles. Ag⁺ self-assembled on the surface of PGMA hemisphere of the functionalized PS/PGMA particles by coordinating with amine/carboxyl. PS/Ag asymmetric hybrid particles with 7.29 wt% of Ag were obtained by reduction of Ag⁺. Scanning electron microscopy, energy-dispersive X-ray spectroscopy and transmission electron microscopy results confirmed that Ag was asymmetrically distributed on the surface of polymer particles.
