Printed Thin Magnetic Films via Ternary Hybrid Diblock Copolymer Films Containing Magnetic Iron Oxide and Nickel Nanoparticles.

ABSTRACT: Ternary hybrid thin films composed of a diblock copolymer templating two types of nanoparticles (NPs) expand the functionality of binary systems, which renders them interesting for magnetic sensing or magnetic data storage applications. Herein, one-pot slot-die printed hybrid polystyrene-block-poly(methyl methacrylate) (PS-b-PMMA) thin films are prepared with iron oxide (magnetite, Fe₃O₄, d = 20 nm) and nickel NPs (Ni, d = 46 nm) in one step by the advanced slot-die coating technique, which facilitates upscaling of fabrication. The evolution of the hybrid film morphology is probed with in situ grazing-incidence small-angle X-ray scattering and compared to that of a PS-b-PMMA thin film without NPs. Additionally, scanning electron micr
