Problems solved by technology

[0016] At present, for single-structure or single-component coatings, the performance is relatively single. To improve its protective performance, the thickness must be increased, and increasing the thickness will lead to performance degradation such as heat dissipation and signal transmission.

Abstract

The invention provides a preparation method for a high-insulation nanometer protection coating with a modulation structure, belonging to the technical field of plasma. According to the method, a reaction cavity is vacuumized and inert gas is introduced to allow a substrate to move; a low dipole moment-organosilicon / fluorocarbon modulated multilayer compact structure is formed through a manner of alternative preparation of a low dipole moment organic coating and an organosilicon coating or an organic fluorocarbon coating, so the stress of the coating can be reduced while the toughness of the coating is improved; meanwhile, since the low dipole moment-organosilicon / fluorocarbon structure has a transverse interface, when a corrosion medium is used for corrosion of the coating, corrosion develops along a transverse direction when the corrosion medium encounters the transverse interface, so longitudinal corrosion penetrating the coating is hard to form and the corrosion medium is preventedfrom penetrating the coating and corroding protected materials and device; moreover, the modulated nanometer layered structure has superlattice effect, and dislocation accumulation formed among layers, so the coating is more unlikely to breakdown and has improved resistance to underwater energization.

Description

technical field [0001] The invention belongs to the technical field of plasma chemical vapor deposition, and in particular relates to a preparation method of a nano protective coating. Background technique [0002] Anti-mold, anti-humidity, and anti-salt mist (referred to as three antis) are important problems that need to be solved during the storage, transportation and use of electronic devices. Mold, salt spray and humidity often cause electronic devices to fail due to short circuits. Therefore, for the protective coating used in the electronics industry, in addition to having excellent "three-proof" performance, it must also have good insulation. [0003] At present, the use of protective coatings to protect electronic products is an effective way to improve the service life of electronic products. There are generally two methods for obtaining protective coatings, liquid phase and gas phase. The liquid phase method usually uses conformal paint. After coating the elect...
