Preparation and Characterization of Magnetic Nanocomposite in a Polymer Matrix By Ion Implantation
type: CreativeWork
description: Recently, research interest in the field of nanocomposite materials is growing rapidly due to their size-dependent interesting electronic and magnetic properties that have many potential applications. Ion implantation is a versatile technique that can create nanocomposite materials with a wide range of interesting electronic and magnetic properties. The scope of the research is to induce ferromagnetic metals into a polymer matrix and perform magnetic and electrical characterization on the material. The addition of the ferromagnetic metals should enhance the magneto resistance of the material and also produce semiconductor behavior. The samples consist of a polymer, poly-ether-ether-ketone (PEEK), implanted with Iron, Nickel, or Cobalt. Thus, creating a nanoparticle embedded into a polymer matrix. Characterizations such as electrical transport, magnetoresistance and Hall effect will be performed on the samples. Low dose and low thickness films showed hopping/semiconducting type behavior in electrical resistance data. In iron nanocomposites negative magnetoresistance was observed. Both ferromagnetism and superparamagnetism have been observed in Fe/PEEK nanocomposites.
