Study of Variation in Pore Diameter with Etching Rate and Fabrication of Copper Nano/Micro Wires Using Electrodeposition Method

In the present work, polycarbonate (Makrofol KG) foils of thickness 10 µm were irradiated with Ag+13 ions (180 MeV) at a fluence of 2E7 ions/cm2. Damages created by ion passage (called the latent tracks) in films were later chemically etched in an aqueous solution of 6 N NaOH solution. Scanning electron microscopy (SEM) images of the so created etched tracks shows the increase in diameter of pores with increasing etch-time. These etched track membranes were later successfully used as template for deposition of copper nano/micro wires via electrodeposition method.
