Abstract Scope |
There is great interest in composites of polymers and multiferroic nanoparticles for advanced electronic applications. There has been very little work done in the rapid prototyping of such composites. We report the fabrication of composites of silicone elastomer, and barium titanate/iron oxide nanoparticles. The process first involves a sonochemical reaction of iron acetate, urea, barium titanate nanoparticles in a solvent. This results in iron oxide nanoparticles formed on and near the barium titanate nanoparticles. A subsequent sintering process improves the crystalline nature of the iron oxide. The barium titanate/iron oxide nanoparticles are combined with a moldable silicone elastomer (Dowsil MS-4007) at 5% weight ratio and loaded onto an extrusion head of a commercial 3D printer. Printing on a base maintained at 100 °C results in the formation of solid nanocomposite layers. Observations will be presented from characterization of these layers by electrical and magnetic studies, microscopy, mechanical and thermal studies. |
