Embodiment 1
[0022] Embodiment 1: A kind of preparation method of chlorine-doped multi-layer graphene film, adopts the solution after the reaction of ethylene glycol and hydrochloric acid according to certain molar ratio to generate chlorine-doped graphene film at one time after spin-coating annealing, including liquid phase chemistry The three steps of reaction, spin coating and annealing are as follows:
[0023] 1) Liquid-phase chemical reaction: Take 30 ml of ethylene glycol and 9 ml of hydrochloric acid, put them in a 100 ml beaker, stir with a mechanical stirrer and heat on the heating plate at the same time, set the temperature of the heating plate to 200°C until the evenly mixed solution becomes Until it is golden yellow and does not continue to change color, keep the uniform brown color and put it in a brown sample bottle for later use;
[0024] 2) Spin coating: Make a 0.5 g / ml solution of the chlorine-doped graphene precursor in step 1) and drop an appropriate amount on the treate...
