Anti-microbial porous part based on polymeric materials grafted benzalkonium with motifs

摘要

The invention concerns an anti-microbial porous part based on a polymeric material grafted at the surface and in its volume with ammonium motifs with anti-microbial and/or bactericidal and/or fungicide activity, preferably benzalkonium. The invention is characterised in that it has a porosity sufficiently high to enable a liquid with compatible viscosity to pass through its structure and sufficiently low to trap contaminating germs within said structure.
