Preparation of Silver nanowire by polyol process

Abstract

One-dimensional nanoscopic materials, such as metal nanorod and nanowire, are currently widely studied because of interests in understanding the physics and the chemistry of nanostructures and in developing new nanodevices. So there have been a number of researches on the preparation methods and functions. Polyol process, a chemical reduction method, will be studied capability to properties and application of other sides. As it used wet chemical method (polyol process), it makes silver nanowire of micro-length(about 5~30㎛) and nano-width(about 50~100nm). In this study, variables put stabilizer`s kinds, the strength of reductants, time and temperature because of analyzing changes of silver nanowire`s physical and chemical properties. Also properties of silver nanowire were analyzed by transmission electron microscopy(TEM), scannin electron microscope (SEM), UV-Vis spectrophotometer. In addition, silver nanowire`s crystallization was observed by X-ray diffration(XRD).
