Problems solved by technology

The performance of a thin film is determined by its internal atomic content and bonding mode. Therefore, choosing a reasonable preparation technology and adjusting the process conditions is the key to obtaining a thin film with excellent performance. Commonly used preparation technologies include plasma-enhanced chemical vapor deposition, dielectric barrier discharge and Pulse laser deposition, etc., but these preparation technologies will bring a series of problems, such as impurity particle pollution, small film preparation area, low component controllability, high cost of reactants and even harmful to the environment, etc.

Abstract

The invention discloses an organic-metal nano composite film as well as a preparation method and application thereof, and belongs to the technical field of composite materials. The organic-metal nanocomposite film is composed of a substrate layer and a fluorocarbon-titanium composite film layer. The preparation method comprises the following steps: grinding a polytetrafluoroethylene target material and a titanium target material, and cleaning; then carrying out pre-sputtering; depositing a fluorocarbon-titanium composite film on the surface of the substrate layer by virtue of co-sputtering; and then carrying out high-temperature annealing to obtain the product. According to the preparation method of the organic-metal nano composite film, the change of the deposition state of the film is changed by adopting the radio-frequency direct-current co-sputtering, so that nanoscale surface appearance and chemical component contents are regulated and controlled; and the crystallinity of the film is regulated and controlled by adjusting a high-temperature annealing process, so that the prepared composite film shows different infiltration properties and secondary electron emission characteristics, and has the advantages of high purity, large deposition area, high controllability of a phase structure and the like, thereby being wide in application and having remarkable popularization and practical values.
