Patent

CA 2721272

A protective material includes a porous substrate having cross-linked self-decontaminating polymer grafted thereon, the crosslinked self-decontaminating polymer having been converted after grafting to activate self-decontaminating function. The cross-linked self- decontaminating polymer provides the protective material with reversible swelling ability to block the porous substrate when the protective barrier is contacted by liquids.

L'invention porte sur une matière protectrice comprenant un substrat poreux ayant un polymère réticulé auto-décontaminant greffé sur celui-ci, le polymère réticulé auto-décontaminant ayant été converti après greffage pour activer la fonction d'auto-décontamination. Le polymère réticulé auto-décontaminant confère à la matière protectrice une aptitude au gonflement réversible pour bloquer le substrat poreux lorsque la barrière protectrice est mise en contact avec des liquides.
