Iron fibers arrays prepared by electrodepositing in reverse liquid crystalline

Abstract

Ordered iron fiber arrays were electrodeposited on the surface of zinc foils using “FeSO₄ solution-sodium caprylate-Decanol” 3-component reverse hexagonal liquid crystal as soft templates. The structure of the soft templates and the synthesized iron fibers were characterized by polarizing microscopy, X-ray diffraction (XRD), scanning electron microscopy (SEM) and energy dispersive X-ray microanalysis etc. The experimental results show that the synthesized iron fibers with a crystal phase grew up in the form of fiber clusters of about 200 nm along the direction perpendicular to the cathode surface. Each cluster was composed of several tens of fibers. The fibers had almost the same length of more than 10 μm with a diameter of about 50 nm.
