Preparation method of anti-bending MXene/carbon composite material heat dissipation film
The invention discloses a preparation method of an anti-bending MXene/carbon composite material heat dissipation film, and relates to a preparation method of a composite material heat dissipation film. The method comprises the following steps: firstly, taking polyimide as a matrix, MXene particles obtained by etching an MAX phase as a reinforcing material, and a polymer easy to form carbon as a middle layer, and fully mixing, reacting, coating and curing to form the MXene/carbon-forming polymer/polyimide composite film; secondly, making the prepared MXene/carbon-forming polymer/polyimide composite film loaded into a high-temperature carbonization furnace, and carrying out high-temperature pyrolysis and carbonization under the protective atmosphere to form the MXene/carbon composite material; and finally, repeatedly cleaning the surface of the film with water and ethanol to obtain the anti-bending MXene/carbon composite material heat dissipation film. The MXene/carbon composite material heat dissipation film prepared by the method not only has excellent heat resistance and heat dissipation performance, but also is light in weight, high in strength and outstanding in bending resistance, and can be used for heat dissipation of high-power electronic equipment, LED backgrounds, micro-electronics, sensing devices and the like.
