Paper Abstract

The Arc Discharge Drawing (ADD) technique offers a promising alternative for fabricating silica nanowires. In the previous study, ADD technique was based on the creation of a high voltage glow discharge between two electrodes. Such a configuration provides the heat zone that occurs perpendicularly to the fiber. With ADD technique, silica wires with diameters as small as 50 nm were achieved. Despite these successes the further development is meant to be continued. In this paper, ADD technique is improved by adding a pair of electrodes. The arc discharge apparatus consisting of four electrodes is proposed. The arranged two pairs of electrodes offer the sandwich-heat source configuration. The computer-controlled stage allows the drawing speeds in the range of 12 mm/s to 25 mm/s. The nanowires can be produced by varying the voltage in the range of 4 kV to 5 kV. The optimum operational voltage is investigated by the scanning electron microscope (SEM) images of the fabricated nanowires. This result strongly suggests further improvements in glass fiber drawing technology to produce nanowires.
