摘要: Multifunctional thin films having both electrical conductivity and ferrimagnetic properties were successfully fabricated by the layer-by-layer self-assembling (LBL-SA) method, i.e. successive ionic adsorption of polypyrrole (PPy) ferrite nanoparticles from their aqueous solutions. Using an ellipsometer, a constant increase film thickness each deposition was characterized, implying controllable process LBL-SA for multifunctional films. Uniformly distributed in also observed scanning transmission electron microscopic images. The consisting six PPy two nanoparticle layers had 0.18 S/cm simultaneously showed magnetic hysteresis.
