Abstract

Articles are provided for absorbing fluids. In embodiments, the articles of the present disclosure are modified to make them hydrophobic, thereby decreasing their affinity for water and similar liquids, while increasing their affinity for other hydrophobic materials, including oil. After use, the articles, in embodiments sponges, may have their absorbed materials removed therefrom, and the articles may then be re-used to absorb additional materials.
