The application belongs to the technical field of graphene materials, and discloses a preparation method of graphene heat dissipation film for electronic equipment by using electron beam technology. The carbonization reaction and graphitization reaction of the organic plastic film are carried out by electron beam irradiation to prepare a semi-finished graphene heat dissipation film, and the graphene heat dissipation film is finally obtained by ion titanium infiltration treatment. The graphene heat dissipation film has excellent heat conduction performance and is suitable for heat dissipation components of portable electronic equipment. The graphene heat dissipation film prepared by the method has excellent heat conduction performance and is suitable for heat dissipation components of portable electronic equipment.

The invention provides a lunar surface drilling method based on a high-energy electron beam technology, which comprises the following steps of: adopting a high-energy electron beam as a non-contact heat knife, melting lunar soil in situ through annular or conical cutting, and condensing to form a high-strength vitrification lining internally packaged with a lunar soil sample; the high-strength vitrification lining is used as an in-situ generated vitrification sleeve to tightly wrap and solidify the lunar soil sample which is not influenced by heat inside to form a lunar soil sample monomer protected by the high-strength vitrification lining, so that in-situ packaging of the lunar soil sample is realized. The invention relates to a lunar surface drilling and in-situ packaging sampling method based on a high-energy electron beam technology, in particular to a method for drilling, sampling and melting hole forming on the surface of the moon by using the high-energy electron beam technology, which is suitable for scientific detection of the moon, in-situ resource utilization and base construction. And more technical means are provided for detection and exploitation of lunar mineral resources.
