TESTING AND MEASURING Structural and Physical Properties of Poly Methyl Methacrylate / Magnetite Nanocomposites

The casting technique was used for the preparation of poly methyl methacrylate (PMMA) nanoparticles at different concentrations of Fe3 O4 . SEM indicated a precise distribution of Fe3 O4 particles in the PMMA matrix up to 10 wt%. XRD reveals an increase in crystallization by increasing the Fe3 O4 content.

At present, nanocomposites consisting of a dielectric matrix and inorganic magnetic particles scattered randomly find intense research because of their electromagnetic and electrical performance. The main applications of these polymer compounds relate to electromagnetic interference, for example, radio frequency interference and electrostatic dispersion coverage.
