A magnetic array fabricated by a novel process constructed with photosensitive polyimide-ferrite nanocomposite

摘要

The authors report an approach to the fabrication of a periodic magnetic array using photosensitive polyimide-barium ferrite nanocomposite.These patterns are shaped by a some-like imprint technique,under the interactions between the magnetic nanoparticles and permanent magnetic mold.Scanning electron microscopy has been used to characterize the magnetic array and well-defined structures with magnetic arrays are obtained.The diameter of each dot is as small as 52um.The presented concept leads to a realization of a magnetic array,which offers advances in achieving micrometer-scale patterns with a very low cost and simple process.
