Abstract Scope |
Composites of polydimethylsiloxane (PDMS), and nano-particles of barium titanate, cobalt ferrite and iron oxide have been fabricated by 3D printing for applications in advanced multiferroic devices. The fabrication involved nano-particle synthesis by sonochemical method, followed by mechanically blending liquid PDMS pre-polymer and its curing agent with the nanoparticles. The blend was loaded onto an extrusion printing head of a commercial 3D printer and printed on a base plate maintained between 75 – 90 °C to yield solid composite layers. Characterization of these composite layers by electrical and magnetic studies, and observations from scanning electron microscopy, transmission electron microscopy, x-ray diffraction, differential scanning calorimetry, thermogravimetry will be presented. To the best of our knowledge, this is the first report of a 3D printing approach to developing polymer multiferroic composites and constitutes a facile route to achieving such functional composites. |
