Summary: | The invention discloses a preparation method of a nano graphite copper material. The preparation method comprises the following steps: taking a copper material as a base material and selecting a high-purity graphite target material; the preparation method comprises the following steps: respectively putting a base material into ethanol, acetone and deionized water, cleaning for 20 minutes through ultrasonic waves, drying at the temperature of 60 DEG C, and finally cooling and rolling; the base material is placed in a vacuum cavity, when the vacuum degree in the vacuum cavity reaches 5-3-20-3 pa, a certain amount of Ar gas is introduced firstly, the pressure in the vacuum cavity is made to be 1-2 Pa, under the conditions that the bias amplitude is 400-600 V and the duty ratio is 30-60%, Ar plasma is used for sputtering the surface of the base material for 10-30 min, and therefore an oxide layer on the surface is removed; a graphite target material is used as a carbon source, a pair of twin alternating current p |
