Reduction method of graphite oxide applied by high voltage potential

摘要

The present invention relates to a graphite oxide reduction method using high voltage application, comprising: a sample preparation step (S1 step) of preparing a graphite oxide sample for reducing oxidized graphite material; A sample aligning step (S2 step) of placing the oxidized graphite sample prepared in the sample preparation step (S1 step) between two electrodes to which high voltage can be applied; And applying a high voltage between the two electrodes (Step S3). A high voltage is applied to the graphite oxide at room temperature, normal humidity, and atmospheric pressure through a voltage supply device which is easy to apply a high voltage, And reducing the graphite oxide only by applying a high voltage, the vacuum chamber, the high temperature and the environment gas as well as the light source are unnecessary, and the expense required for reducing the graphite oxide is minimized and the economical efficiency is excellent. It is a useful invention having a particular advantage that the preparation and post-treatment steps of the sample can be easily reduced, and the performance of the sample is improved by reducing the film-shaped graphite sample to a high reduction level.
