Direct fluorination

Direct fluorination is a particularly energetic chemical process that involves exposing a material to fluorine gas (F₂) under specific conditions. This method allows fluorine atoms to be introduced directly into the chemical structure of the material’s surface, significantly modifying its properties.

A few examples of applications

Thanks to its unique properties,  has a wide range of applications:

Chemical industry: passivation of metallic surfaces for improved corrosion resistance, “superfluorination” of fluorinated plastics sush as PTFE, PFA and perfluoroelastomers (FKMs and FFKMs).
Plastic industry: adhesion and permeability modification, wettability, thermal resistance.
Biomedicine: Manufacture of medical devices (catheters, prostheses) with biocompatible surfaces.

Advantages :

Surface Modification Only: The process selectively alters surface properties without affecting the bulk material.
Versatility: Applicable to a wide range of materials and applications.
Process Simplicity: Generally involves straightforward procedures.
