Example Embodiment
[0026] Example 1
[0027] The high thermal stability iodine-doped graphene film of this embodiment is composed of multilayer graphene microsheets mixed with iodine dopants. The multilayer graphene microsheets are randomly stacked along the plane direction. Exist in the form of atoms and ions.
[0028] The preparation method of the high thermal stability iodine-doped graphene film of this embodiment includes the following steps:
[0029] Step 1. Wash and dry the glass in sequence;
[0030] Step 2: Add 50g of graphite powder to 1L of N-methylpyrrolidone, stir at 4000 rpm for 30 minutes and then stand for 3 hours to obtain a graphene microplatelet suspension. The graphene microplatelet suspension contains graphite The number of layers of the olefin microchips is 2 to 4, and 10g of ethyl cellulose is added to the graphene microchip suspension, and then the precipitated particles are removed by centrifugation to obtain a supernatant, and ethylene glycol is added to the supernatant to adju...
