Solvent-Free Atom Transfer Radical Polymerization in the Synthesis of Fe2O3@Polystyrene Core−Shell Nanoparticles
Abstract
This paper describes the use of solvent-free atom transfer radical polymerization (ATRP) in the synthesis of Fe 2 O 3 @polystyrene (PS) core−shell nanoparticles. In this approach, oleic acid stabilized Fe 2 O 3 nanoparticles were ligand exchanged with 2-bromo-2-methylpropionic acid (Br-MPA), the initiator for ATRP. These Fe 2 O 3 nanoparticles become soluble in styrene and can be used as macroinitiators for solvent-free ATRP. The synthesized core−shell nanoparticles were characterized by transmission electron microscopy (TEM), gel permeation chromatography (GPC), differential scanning calorimetry (DSC), ultraviolet−visible (UV−vis) spectroscopy, and Fourier transform-infrared (FT-IR) spectroscopy. Well-defined Fe 2 O 3 @PS core−shell nanoparticles were obtained. The glassy transition temperature of PS was studied using DSC, and the molecular weight of PS was characterized by GPC. The unique aspects of this solvent-free ATRP in the synthesis of well-defined polymer-coated nanoparticles will be discussed.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
