Bifunctional Fe_3O_4/CdS Nanocomposites Synthesized by Surface-initiated Atom Transfer Radical Polymerization

摘要

This paper described the fabrication of a new Fe_3O_4/CdS nanocomposite.PCd(MA)_2 was firstly polymerized by surface-initiated atom transfer radical polymerization (ATRP) on the surface of Fe_3O_4 nanoparticles,and then the formation of CdS nanoparticles took place in situ when S~(2~) 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.
