Amphiphilic Janus graphite particle as well as preparation method and application thereof

The invention discloses an amphiphilic Janus micro-nano graphite particle, and in an FITR spectrum of the amphiphilic Janus micro-nano graphite particle, vibration peaks exist at positions near 3100 to 3200 cm , near 3030 to 3050 cm , near 1600 to 1700 cm , and near 1550 to 1580 cm , such as near 3100 to 3200 cm , near 3030 to 3050 cm , near 1600 to 1700 cm , and near 1550 to 1580 cm . The invention also discloses a preparation method and an application method of the amphiphilic Janus micro-nano graphite particle. According to the preparation method disclosed by the invention, the micro-nano graphite particles are subjected to heterogeneous modification, so that the micro-nano graphite particles can be modified into the amphiphilic Janus graphite particles of which one ends have hydrophilic characteristics and the other ends have hydrophobic characteristics. Through application evaluation of the amphiphilic Janus graphite particles in the drilling fluid, the lubricating
