A downhole article includes an ion exchange polymer; and a composition that includes an elastomer and an absorbent material. A method of maintaining expandability of a downhole article includes disposing a downhole article comprising an elastomer, absorbent material, and an ion exchange material in a borehole, the ion exchange material comprising host ions; and exchanging fluid ions in a fluid with host ions from the ion exchange material to maintain the expandability of the downhole article. |
