Abstract Scope |
This work investigates ferromagnetic and dielectric materials with an emphasis on cobalt, nickel, iron, PVDF and P(VDF-TrFE).
Cobalt ferrite is synthesized using the sonochemical method. These nanoparticles are then infused into the PVDF polymer and its co polymer P(VDF-TrFE) to fabricate 100 micrometers thick, thin films. First is the synthetization of magnetic nanoparticles, specifically cobalt ferrite nanoparticles using bottom-up approach via ultrasonication method at 50nm diameter or less. Secondly, use the as-synthesized nanoparticles to determine if they could fill the hole gaps in a polymer matrix, then prepare a composite film using the doctor blading technique to test their coupling effect.
The synthesized cobalt ferrite nanoparticles at 300K showed higher coercivity than the nickel ferrite nanoparticles. The size of the magnetic particle determined its energy in an external field. This relation is essentially through the number of magnetic molecules in an individual magnetic domain. |
