SURFACE-MODIFIED FIBROUS MATERIAL AS A FILTRATION MEDIUM
A surface-modified fibrous material which includes hydrocarbon polymer fibers having cationic or anionic groups on the surfaces thereof and coated with a polyelectrolyte having a net charge opposite to that of the cationic or anionic groups on the surfaces of the fibers. The hydrocarbon polymer may...

| description | A surface-modified fibrous material which includes hydrocarbon polymer fibers having cationic or anionic groups on the surfaces thereof and coated with a polyelectrolyte having a net charge opposite to that of the cationic or anionic groups on the surfaces of the fibers. The hydrocarbon polymer may be, by way of illustration, a polyolefin, such as polyethylene or polypropylene. The cationic or anionic groups may be carboxylic acid, sulfonic acid groups, or quaternary ammonium groups. Examples of polyelectrolytes include chitosan, poly(methacryloxyethyltrimethylammonium bromide), poly(acrylic acid), and poly(styrene sulfonate). Also disclosed is a method of making the surface-modified fibrous material. The surface-modified fibrous material may be used as a filtration medium for liquids.
L'invention porte sur un matériau fibreux comportant des fibres d'un polymère hydrocarboné à groupes cationiques et anioniques superficiels et revêtues d'un polyélectrolyte dont la charge nette est l'opposé de celle des groupes cationiques et anioniques de la surface des fibres. Le polymère hydrocarboné peut être par exemple une polyoléfine telle que du polyéthylène ou de polypropylène. Les groupes cationiques ou anioniques peuvent être des groupes acide carboxylique, acide sulfonique, ou ammonium quaternaire. Parmi les exemples de polyélectrolytes, citons le chitosan, le bromure de poly(méthacryloxyéthyltriméthylammonium, le poly(acide acrylique), et le poly(sulfonate de styrène). L'invention porte également sur un procédé de fabrication dudit matériau fibreux modifié en surface qui peut servir de milieu filtrant pour liquides. |
