The invention discloses a double-gun jointly spraying composite film preparation technology based on immiscible function materials. Immiscible film material liquids are sprayed to the surface of the same target device by different spray guns respectively to form a composite film. The composite film preparation technology based on two immiscible function materials has the advantages that organic and inorganic materials which cannot be composited into a film with a conventional technology of film formation from solutions can be combined in a standard gaseous state and a dispersed state, so that an organic and inorganic material composite film is formed through deposition. The method can be used for preparing the organic and inorganic material composite film and can also be used for ordinary film formation, large-area film formation, film formation of a device with a complicated structure, film formation of a flexible material and various film formation forms such as chemical reaction film formation, physical deposition film formation and the like.
Description
technical field [0001] The invention relates to the field of thin film preparation technology, in particular to the thin film preparation technology of organic-inorganic composite materials. Background technique [0002] With the miniaturization, convenience and industrialization of electronic devices, thin film materials have become a trend in the preparation and application of electronic devices. Thin film materials are characterized by lightness, quickness and less consumables, and can be widely used in various fields, which is the trend of material development. With the development of thin-film materials, thin-film film-forming technology has become an important topic in the development of thin-film materials. Due to different material characteristics and device requirements, various thin-film film-forming processes have emerged. Each film-forming process has its own advantages. Each has its own characteristics and has made considerable progress in its respective fields...
