Bifunctional Fe3O4/CdS Nanocomposites Synthesized by Surface-initiated Atom Transfer Radical Polymerization

Abstract

Abstract This paper described the fabrication of a new Fe3O4/CdS nanocomposite. PCd(MA)2 was firstly polymerized by surface-initiated atom transfer radical polymerization (ATRP) on the surface of Fe3O4 nanoparticles, and then the formation of CdS nanoparticles took place in situ when S2− ions were released by thioacetamide upon heating. The nanocomposites were characterized by XPS, TEM, and UV–vis. The PL and magnetic properties were also studied.
