| The objective of the study is to design novel nanocomposite based thiol-ene photopolymers and magnetite nanoparticles for potential application in hyperthermia or controlled drug release. Advantages of such materials are easy fabrication into any shapes and photocuring even in vivo. The magnetic nanoparticles were synthesized using iron salts in the presence of base, stabilized with an undecylenic acid as coating.Particle size and distribution were determined by TEM and Zetasizer. Elastomeric photopolymers homogeneously incorporating these magnetite nanoparticles were synthesized using the trifunctional thiol trimethylol propane tri (3-mercaptopropionate) and the difunctional ene trimethylolpropanediallylether using irgacure 184 as photoinitiator. Nanocomposites with different magnetite contents were prepared and their thermal behavior investigated using DSC and TGA. |
