Large scale copper microstructures generation using electro-deposition through nuclear track filters

Nuclear track filters of Makrofol (KG) polycarbonate with pore size ca. 2.6μm and pore density 1x106 cm-2 were used as templates for synthesis of copper microstructures using the technique of electrodeposition. Since the membranes used contain cylindrical pores of uniform diameter, crops of monodisperse microstructures of the desired material, whose dimensions can be carefully controlled, were obtained. Track etch membranes in the form of nuclear track filters have emerged as a spin-off from solid state nuclear track detectors (SSNTDs)-solid dielectric materials capable of storing tracks of energetic, heavily ionizing ions which can subsequently chemically amplified for optical observations as pores or channels of well defined geometry and pore density.
