SWELLABLE ARTICLE

摘要

A swellable article, including a matrix material and an exfoliatable graphene-based material disposed in the matrix material. The exfoliatable graphene-based material is operatively arranged to facilitate swelling of the swellable article upon exposure to a selected fluid by sorbing particles in the fluid. The swelling enables the swellable article to engage an adjacent structure. Methods of making and using a swellable article are also included.

主权项

1. A method of making a swellable article comprising:
disposing a graphene-based material in a matrix material to yield a swellable material; forming the swellable material into an article that is swellably responsive to a selected fluid, exfoliating the graphene-based material in the article; and the graphene-based material operatively arranged to facilitate swelling of the swellable article upon exposure to a selected fluid by sorbing the fluid.
