The military textiles used to dress the combatant are surface-treated with perfluorinated compounds to provide the textiles with impermeability to water and fat, two essential properties to prevent the penetration of CBRN war toxics. However, these PFAS pose environmental and health risks that will lead to their prohibition by 2030. There is therefore an urge to find alternatives.
The AMPHITEX project aims to develop innovative amphiphobic and sustainable textiles combining surface activation, multi-scale structuration and functionalization with silicone-based polymers (PDMS) and inorganic particles. This project involves 5 teams within three IP Paris laboratories : PMC laboratory and LSO “organic chemistry laboratory” at the Ecole Polytechnique and the unit « Chemistry and Processes » at ENTSA. In our ECM group, we mainly work on the activation of textiles by physical processes such as light, UV-ozonolysis, and plasma (Ar, O2) at low pressure to generate new chemical functions and roughness on the surface of textiles. In collaboration with the Plasma Physics Laboratory (LPP) at the Ecole Polytechnique, we also use cold plasma at atmospheric pressure or with other gases.
