Specific Features of Obtaining of Metal Nanowires by Replication of Pores of Track Etched Membranes

Abstract

Ensembles (massives) of metal nanowires (with diameters 50-200 nm) were obtained using method of template synthesis. Polymer track etched matrixes were used as template. Nanowires obtained were the replicas of the pores in these membranes. The problems of choosing of electrolyte and different regimes of electrodeposition were discussed. Different techniques of separation of obtained nanowires from growth polymer matrix were used-etching at elevated temperature, ultrasound and UV-treatment. The regimes of obtaining of layer Cu/Ni nanowires were investigated and the optimal voltages were found: 0.8 V for Cu-layer and 1.8 for Ni layer. It was also found that application of magnetic field accelerate the process of electrodeposition; moreover, application of SOUTH pole leads to formation of hollow Ni-layers. Using of “two-bath” method of electrodeposition found to be optimal for obtaining of two-parts wires. Such wires could be used for generation of THz irradiation.
