Fabrication of magnetic polymers from synthesized and commercial ferrofluids

In this study commercially provided and laboratory synthesized ferrofluids which are a mixture of ultra-small magnetic particles in colloids were deposited on commercial hard disk media. The hard disk media which have different dipole moment densities were cut as 1.5 cm coupons and used as deposition under layers. To fabricate ferrofluid-polymer compositions deposited ferrofluids were transferred to polymers. Morphologies of the deposited coupons were studied by optical microscope and atomic force microscopy (AFM). Magnetic properties of the deposited polymers were investigated by a vibrational sample magnetometer (VSM). Structural characterizations of the synthesized ferrofluid nanoparticles were completed by an X-ray diffractometer (XRD).
