Electrical properties arrays of intersecting of nanowires obtained in the pores of track membranes

In the following work by means of matrix synthesis the nanowire arrays of Fe–Ni alloy with elemental composition close to permalloy (Fe 0·20 Ni 0.80 ) were obtained. In capacity of matrix the polyethylene terephthalate (PET) track membranes with angular distribution of pores within the range of ±30° and the diameter of pores in 100 nm were used. As a result, via electrochemical deposition method the metal-polymer composite in the form of nanowire arrays in the polymeric matrix were obtained. The distribution of pores over the surface of track membranes and the average amount of nanowire intersections under a variety of lengths of the grown nanowires were calculated. The resistivity of metal-polymer composite arrays, formed with nanowires of varying length, was measured. The growth boundary conditions and the lengths of nanowire arrays that are essential for obtaining of conducting metal-polymer composite were determined. • The PET track membrane (TM) used for the growth of nanowires was characterized. • A model for calculating the number of intersections of nanowires was proposed. • Resistance of an array of Fe 0.2 Ni 0.8 nanowires was measured. • The correlation between the l and the N cros. res. with 1/R average was established.
