摘要
A cost-effective chemical synthesis and single-step magnetic patterning of iron nanoparticles (size approximate to 100 nm) in a semiconducting P3OT polymer matrix is reported wherein Fe nanostructures (approximate to 150 +/- 50 nm) are periodically aligned with pi-conjugated P3OT chains to form a nanomagnet-semiconductor-nanomagnet (Fe-pi-Fe) structure. The resultant periodic patterning has been characterized by XRD, SEM and AFM techniques and is attributed to the intrinsic alignment of Fe at the nanometer-scale level in a conjugated polymer matrix under the influence of a magnetic field. Such a P3OT/Fe matrix may find application in magnetic memory devices.
