Embodiment 1
[0030] The nano-carbon crystal layer is coated on the heat-conducting aluminum plate through a spraying process. Described spraying process comprises the steps:
[0031] Surface treatment of graphene: First, disperse graphene and dispersant in ferric chloride solution under the action of ultrasonic waves, and continue to react for 3 hours under nitrogen protection under low boiling conditions, and finally add dilute hydrochloric acid to remove nanometer particles in the solution. Grade iron oxide particles, washed with water until neutral, filtered, and dried for use; then the above-mentioned graphene and dispersant were dispersed in isopropanol under the action of ultrasonic waves to form a suspension, and then the silane coupling agent KH- 570 solution, in which the mass ratio of graphene to silane coupling agent KH-570 is 1:1.5; then, under the condition of reflux at 85°C, keep stirring for 4h, then filter, wash with water, and dry to obtain black silylated graphite alkene...
