Abstract: Membranes of the present disclosure possess very thin barrier layers, with high selectivity, high throughput, low fouling, and are long lasting. The membranes include graphene and/or graphene oxide barrier layers on a nanofibrous supporting scaffold. Methods for forming these membranes, as well as uses thereof, are also provided. In embodiments, an article of the present disclosure includes a nanofibrous scaffold; at least a first layer of nanoporous graphene, nanoporous graphene oxide, or combinations thereof on at least a portion of a surface of the nanofibrous scaffold; an additive such as crosslinking agents and/or particles on an outer surface of the at least first layer of nanoporous graphene, nanoporous graphene oxide, or combinations thereof.

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.

Abstract: Water filtration membranes are provided. Such membranes include polysaccharide fibers that have been modified to possess thiol groups thereon, resulting in materials that effectively bind heavy metal ions. The resulting fibers may be used by themselves or applied to a scaffold to form a membrane suitable for removing heavy metals from water, including groundwater.
