An array of iron nanowires encapsulated inpolyaniline nanotubules and its magnetic behavior

Author affiliations


An array of iron nanowires within polyaniline nanotubules was obtained using a two-step template synthesis. First, an array of polyaniline nanotubules was synthesized in an alumina template, and then it was used as a “second-order template” for electrodeposition of iron within the polyaniline nanotubules. The polyaniline envelope may protect the iron nanowires against the corrosive atmosphere. The composite nanostructure was characterized by EDX, XRD and SEM and its magnetic properties were measured by VSM. Coercive forces of the array of iron nanowires encapsulated within polyaniline range from about 119 to 210 Oe with an increase from 0 to 90° for θ, the angle between the applied field and the surface of the alumina template. The array has the axis of easy magnetization in the membrane plane and may be a promising candidate for horizontal magnetic recording materials.
