Coatings dielectric fluoropolymer film

Dielectric fluoropolymer film coatings are used on the surfaces of metal oxides materials in order to build micro- and nanoequipment. To analyze these contacts, quantum calculations were carried out to get the electronic state densities and bond energy between metal oxide and the fluoropolymer. Thus, processes that occur during the formation of fluoropolymer coatings on those oxides can be better understood. 

Conformal coatings. Deposition of a thin film that nniformly coats all exposed parts of a three-dimensional strnctnre is known as conformal film growth. Conformality is a common requirement for dielectric films. Penetration and uniform coverage of all topography and interstices are vital and depend upon low viscosity, as well as low surface and interfacial energies. Fluoropolymer in supercritical solution might provide die required characteristics. 

Vinylidene Fluoride Hexafluoropropylene Copolymer - Thermoplastic copolymer of vinylidene fluoride and hexafluoropropylene. Has better thermal stability, antistick, dielectric, and antifriction properties, and chemical resistance, but lower mechanical strength at room temperature and creep resistance, compared to incompletely fluorinated fluoropolymers. Processing by conventional thermoplastic techniques is difficult due to its high melt viscosity. Uses include chemical apparatus, containers, films, and coatings. Also called TAM... 

In recent years, considerable attention hcis been devoted to the preparation of fluorine-containing polymers due to their unique properties and high-temperature performance. The incorporation of fluorine atoms (or groups containing fluorine atoms) into polymer chains changes solubility of polymers, glass transition temperature (T ) and thermal stability, while also led to decreased moisture absorption and dielectric constant. The aromatic fluoropolymers have currently been used as films, coatings microelectronics devices [37,55-60].
