Large-scale preparation method of monatomic embedded fullerene

The invention discloses a large-scale preparation method of monatomic embedded fullerene. The method comprises the steps: firstly, blade-coating a fullerene film layer on a deposition substrate by adopting a wet-process scraping mode; mounting the deposition substrate copper foil coated with the fullerene thin film layer on a winding motor, and winding the fullerene thin film layer to an ion beam bombardment area by using the winding motor to realize roll-to-roll continuous batch ion implantation; and finally, ionizing non-metal gas or inert gas in a reaction chamber through an ion source, enabling atmosphere containing non-metal or inert gas positive ions to pass through an ion gun screen electrode and an accelerating electrode to be accelerated to form an ion beam containing non-metal or inert gas positive ions, and after the ion beam is neutralized by electrons emitted by a neutralizing electrode, bombarding on the fullerene film layer on the copper foil to obtain the embedded fullerene.
