MODIFIED HYDROPHOBIC SPONGES

摘要

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.

主权项

1. An article comprising a natural porous substrate, the porous substrate possessing at least on surface treated with a silicon material to render the porous substrate hydrophobic, wherein the porous substrate exhibits an increase in weight from about 3 times to about 16 times the initial weight of the porous substrate upon exposure to a hydrophobic material.
