Polymer nanocomposites with tunable magnetic properties
Polymer nanocomposites filleded with iron oxide nanoparticles have been successfully fabricated through different various approaches within different polymer matrix such as thermosetting vinyl ester resin, rubbery polyurethane and conjugated conductive polypyrrole. A bi-functional coupling agent, methacryloxypropyl-trimethoxysilane (MPS) was utilized to functionalize the nanoparticles favoring iron oxide nanoparticle dispersion in the vinyl ester resin matrix and enhancing the interfacial bondage between the nanoparticles and the polymer matrix. A surface-initiated-polymerization (SIP) method was employed to fabricate the iron oxide nanoparticles reinforced polyurethane nanocomposites without any surfactant or coupling agent. The conductive polypyrrole was utilized for the conductive polymer nanocomposite fabrication by a monomer oxidation approach. The magnetic properties of the polymer nanocomposites were observed to depend not only on the nanoparticle loadings but also on the polymer matrix.
