Synthesis, Characterization and Polymerization of Hydrophilic Monomer on Magnetite Nanoparticles via SI-ATRP

In this work, we synthesis and characterization of hydrophilic monomer and performed modification of magnetite nanoparticles via surface-initiated atom transfer radical polymerization (SI-ATRP). Magnetic nanoparticles grafted with poly (2-(2-Ethoxyethoxy) Ethyl acrylate) (PEEA) via SI-ATRP. The results showed that 2-(2-Ethoxyethoxy)ethyl acrylate (EEA) as a monomer was prepared successfully, as well as polymerization of this monomer was performed on the surface of magnetite nanoparticles by SI-ATRP method using CuBr and 3-(2- Aminoethylamino) propyltrimethoxysilane as a ligand. This paper describes the use of SI-ATRP in the synthesis of Fe3O4@SiO2@poly(2-(2-Ethoxyethoxy)ethyl acrylate) (PEEA) core-shell nanoparticles. Fe3O4@SiO2-Br nanoparticles can be used as macroinitiators for ATRP. The functionalized magnetite nanoparticles have been characterized by Fourier transform-infrared (FT-IR) spectroscopy and 1H NMR.
