Abstract
A novel Au/PDVB core-shell was prepared by the chemical reduction of a gold-phenanthroline complex on the poly(divinylbenzene) (PDVB) cores (2–5 μm). The PDVB cores were synthesized by precipitation polymerization, and the surface was modified by introducing thiol and sulfonic acid groups. The degree of sulfonation was measured according to its ion exchange capacity (IEC, 5.72 meq/g), and the surface concentration of thiol group was examined by FT-IR spectroscopy. The modified PDVB cores was immersed in a solution of a gold-phenanthroline complex and subsequently reduced to form gold seeds. The effects of the functional groups on the PDVB cores on fabrication of the gold core shell structure were examined.
