Patent

CA 2469739

The application discloses methods of plasma treatment that employ an ion sheath in a capacitively-coupled system to increase the hydrophilicity of porous articles, including microporous articles having pore sizes of 0.05 to 1.5 micrometers, both on their surfaces and in their pores such that the articles' bulk wetting properties are improved.

Cette application concerne des procédés de traitement par plasma qui utilisent une gaine d'ions dans un système couplé de manière capacitive de façon à augmenter la capacité hydrophile d'articles poreux, y compris des articles microporeux dont la taille des pores est comprise entre 0,05 micromètre et 1,5 micromètre, tant sur leurs surfaces que dans leurs pores de sorte que les propriétés de mouillage dans la masse de ces articles soient améliorées.
