Abstract
A swellable system reactive to a flow of fluid including an article having a swellable material operatively arranged to swell upon exposure to a flow of fluid containing ions therein. A filter material is disposed with the swellable material and operatively arranged to remove the ions from the flow of fluid before exposure to the swellable material.
Claims18
A swellable system reactive to a flow of fluid, comprising:
- an article including a swellable material operatively arranged to swell upon exposure to the flow of fluid, the fluid being aqueous and containing metallic cations from dissolved salts;
- and
- a filter material disposed with the swellable material and operatively arranged to remove the polyvalent cations from the flow of fluid before exposure to the swellable material,
- the filter material comprising a graphene-based material, the graphene-based material comprising at least one functional group operatively arranged to capture the polyvalent cations;
- wherein the filter material and the swellable material are mixed homogeneously in the article.
