Abstract
The invention relates to an adsorption filter material () that provides protection against chemical toxins, chemical weapons and pollutants, with a preferably multi-layer composite construction (). The layer construction () includes at least one planar support layer () with two opposing sides () and an adsorption layer (), provided on the support layer () made from a material which adsorbs chemical toxins, the surface of at least one of the both sides (and/or) of the support layer () being modified by plasma treatment. The surface properties, in particular the surface finish and the surface reactivity can be adjusted and optimised to match the application by means of the plasma treatment.
