  • Publication number: 20210059876
    Abstract: A disposable absorbent product includes a double-network polymer element including a cross-linked, covalently-bonded polymer and a reversible, partially ionicly-bonded polymer, wherein the element has a moisture level less than or equal to 15 percent of the total weight of the element, wherein the element comprises a latent retractive force, and wherein the element is configured to release the retractive force to achieve a dimensional change in the disposable absorbent product with exposure of the element to an aqueous liquid. Manufacturing a disposable absorbent product includes producing a double-network hydrogel; elongating by force and dehydrating while still elongated the double-network hydrogel, wherein elongating and dehydrating captures a latent retractive force in the element; and positioning the element in a disposable absorbent product such that a dimensional change in the disposable absorbent product is achieved with exposure of the element to an aqueous liquid.
