Abstract

Magnetoelectric nanocomposites of cobalt ferrite cores with barium titanate shells are studied for applications in wireless sensor networks. Inkjet printing is an additive manufacturing method for depositing functional nanomaterials in micrometer scale patterns. This work investigates the fabrication of cobalt ferrite, barium titanate nanocomposites with 0:3 connectivity into micrometer dot arrays assisted by inline ultraviolet (UV) and Near Infrared (NIR) photonic processing to remove the ink solvent. Sol-gel synthesis of the cubic spinel cobalt ferrite and tetragonal perovskite barium titanate is confirmed by XRD with nanoparticle diameters less than 200 nm observed by SEM. UV-vis and FTIR absorption spectra of ink solvents and nanocomposite are used to explain the impact of UV and NIR photonic processing. Experiments printing cobalt ferrite, barium titanate nanocomposite ink yield arrays of features 20 to 30 μm in diameter.
