Preparation of polymer nanocomposites of core–shell structure via surface-initiated atom transfer radical polymerizations

Polymer nanocomposites of core–shell structure were prepared by grafting poly(tert-butyl acrylate) (Pt-BA) from SiO2 nanoparticle via the surface-initiated polymerization (SIP) strategy. This new organic inorganic hybrid particle has been extensively characterized by XPS (X-ray Photoelectron Spectroscopy), SEM (Scanning Electron Microscopy), TEM (Transmission Electron Microscopy), and TGA (ThermoGravimetric Analysis).
