Title

GRAFTING POLYDIMETHYL AMINOETHYL METHAACRYLATE ON HYDROXYAPATITE NANOPARTICLES VIA SURFACE-INITIATED ATOM TRANSFER RADICAL POLYMERIZATION

Pages

  -

Abstract

 HYDROXYAPATITE NANOPARTICLES ARE USED WIDELY IN BONE REPLACEMENT AND TISSUE ENGINEERING. SURFACE-INITIATED ATRP ON HA PARTICLES USING DMAEMA MONOMERS IS CARRIED OUT IN THIS WORK IN ORDER TO OBTAIN OPTIMUM MECHANICAL PROPERTIES IN THE RESULTANT POLYMER-MATRIX COMPOSITE. FIRST, NH2-HA PARTICLES ARE SYNTHESIZED USING APTES, AND THEN INITIATOR-FUNCTIONALIZED HA PARTICLES, BR-HA, ARE SYNTHESIZED USING 2-BROMOISOBUTYRYL BROMIDE. SURFACE INITIATED ATRP IS THEN CARRIED OUT WITH DMAEMA MONOMERS RESULTING IN GRAFTED-HA PARTICLES. FTIR AND TGA TESTS ARE DONE TO INVESTIGATE THE GRAFTING OF POLYMERIC CHAINS ON THE HA SURFACE AND TO DETERMINE THE GRAFTING DENSITY OF THE CHAINS. RESULTS SHOW A SUCCESSFUL SYNTHESIS OF GRAFTED-HA PARTICLES THAT CAN BE USED IN BIOMEDICAL APPLICATIONS DUE TO THEIR ENHANCED MECHANICAL PROPERTIES.
