EFFECT OF MICROWAVE IRRADIATION ON COPPER NANOWIRES SYNTHESIZED BY ELECTROCHEMICAL DEPOSITION THROUGH ION TRACK MEMBRANES AS TEMPLATES

摘要

15 μm thick polycarbonate films were irradiated with Ni ions (11.64 MeV) having fluence of the order of 106 ions/cm2. Irradiated foils were etched chemically in 6N NaOH solution at 50°C for 12 minutes to obtain the cylindrical pores having average diameter of 100 nm. Cylindrical pores in these membranes have been used as templates for the synthesis of copper nanowires. A two-electrode electrochemical cell was used for copper electrodeposition in porous polycarbonate templates from acidic copper sulphate solution at 29 ± 1°C. The morphology of copper nanowires were studied by means of scanning electron microscopy (SEM). Effects of microwave treatment on these nanowires were also studied.
