Self-Assembly of 4-Vinylbenzoic Acid Layer on the Magnetic Nanoparticles and In Situ Polymerization

Abstract:

A new method for fabrication of core-shell functional polymer coated nanoparticles was proposed in this work. At first the magnetite particles were wrapped with single-layer oleic acid for getting a hydrophobic surface. Then the monomer molecules of 4-vinylbenzoic acid were fabricated onto this layer by self-assembly and finally in-situ polymerization was taken place for obtaining the functional polymer coated nanoparticles with –COOH groups outside. The nanoparticles were characterized by FTIR, TEM, magnetic property, etc. The results showed that the size of the particle was less than 20 nm in diameter and had a very good property of superparamagnetism.
