Fluorine material thin film is a functional thin film material with excellent performance, made of fluoride polymers. It has characteristics such as low surface energy, high temperature resistance, corrosion resistance, and adhesion resistance, and is widely used in many fields. The following is an introduction to the current mainstream fluorine material films and their applications:
Polytetrafluoroethylene (PTFE) film: PTFE film is a fluorine material film with excellent high temperature resistance, corrosion resistance, and low friction coefficient. It is widely used in electronic, medical, chemical and other fields. In the field of electronics, PTFE film is commonly used for making high-frequency cables, electronic insulation materials, and capacitors; In the medical field, PTFE films are used as materials for medical devices such as artificial blood vessels and Artificial heart valves.
Polyvinylidene fluoride (PVDF) film: PVDF film is a fluorine material film with good weather resistance, corrosion resistance, and electrical properties. It is widely used in fields such as batteries, capacitors, sensors, filter membranes, etc. In the field of batteries, PVDF thin films are commonly used as separator materials for lithium-ion batteries; In the field of sensors, PVDF thin films are used as sensing layers for pressure sensors, temperature sensors, etc.
Polyfluoropropylene (PFA) film: PFA film is a fluorine material film with excellent corrosion resistance, heat resistance, and electrical insulation. It is widely used in fields such as chemical engineering, electronics, and food. In the field of chemical engineering, PFA films are commonly used for making lining of chemical reactors, coating of pipelines, etc; In the field of electronics, PFA film is used as the insulation layer for high-temperature cables; In the food industry, PFA film is used as the inner lining of food packaging materials.
The production of fluorine material films requires the following technologies:
Solution pouring method: Dissolve the fluoropolymer in a solvent, then pour the solution onto a flat plate or roller, and solidify the solution into a thin film by volatilizing the solvent.
Melt extrusion method: The fluoropolymer is heated and melted, and then the molten polymer is extruded into a thin film through an extruder.
Stretching method: The fluoropolymer is heated and melted, and then the molten polymer is stretched into a thin film through stretching machinery.
Chemical vapor deposition method: By gas phase reaction, fluoropolymer is deposited on the surface of the substrate to form a fluorine material film.
To sum up, the current mainstream fluorinated material films include PTFE films, PVDF films and PFA films, which are widely used in the fields of electronics, medical treatment, chemical industry, batteries, etc. The production of these fluorine material films requires techniques such as solution casting, melt extrusion, stretching, and chemical vapor deposition. With the continuous development of technology, the application of fluorine material films in various fields will be further expanded and deepened.
