Metallic Nanowires on the Base of Porous Matrixes: Obtaining by Galvanic Replication, Structure and Some Properties

Abstract

In this work nanowires (Co, Ni and Fe) were obtained via template synthesis, using etched track polymer matrix. The peculiarity of electrodeposition of Co and Ni was investigated and discussed: When filling the pores of a small diameter (0.1 and 0.2 microns) the dependence of current on time passes through a minimum. It can be supposed that the difficulties, appearing while filling nanosized pores, are related to the peculiarities of diffusion in narrow channels. The electrolyte for Fe deposition into nanosized pores was selected, the necessity of agitation was demonstrated. The results of X-rays analysis demonstrate that obtained wires have polycrystalline structure, which slightly depends on the deposition voltage. Mossbauer spectroscopy was used for investigation of Fe samples. The obtained sextet corresponds to α-Fe with polycrystalline structure. Two types of Fe atoms were found. The presence of two types of oxides was also detected. When you are citing the document, use the following link http://essuir.sumdu.edu.ua/handle/123456789/34949
