Polytetrafluoroethylene (PTFE) sodium vapor solution treatment bonding method: Sodium naphthalene solution is used to treat fluorine-containing materials, mainly through chemical reaction between high etching solution and PTFE plastic, pulling away some fluorine atoms on the surface of the material, leaving a carbonization layer and certain polar groups on the surface.

The treatment of fluorinated materials with sodium naphthalene solution mainly involves the chemical reaction between the corrosion solution and PTFE plastic, which tears off some of the fluorogen on the surface of the material, leaving a carbonized layer and some of its polar functional groups on the surface. Infrared spectroscopy shows that polar groups such as hydroxyl, carbonyl, and unsaturated bonds are introduced on the surface, which can increase surface energy, reduce contact angle, improve wetting and mixing, and change from difficult to sticky to sticky. This is the most effective and atmospheric pressure method among all the methods studied recently. Generally, sodium tea tetrahydrofuran is used as the etching solution.
