Abstract: Electrospun poly(acrylic) acid (PAA)/poly(vinyl) alcohol PVA nanofibers and integrated filtration membranes generated therefrom are disclosed herein. The membranes are suitable for use in selectively removing heavy metals such as lead and cadmium from water. The surface of the nanofibers is preferably functionalized with one or more chelating agents. The membranes have a high removal efficiency and adsorption capacity with well-distributed high-density heavy metal adsorption sites with strong binding affinities for targeted heavy metals.

Abstract: A novel solar-powered desalination and water purification system is disclosed herein. The system includes a nanofiber-impregnated graphene aerogel, an untreated water source, a water collection surface, and a purified water storage container. A novel photocatalytic nanofiber-impregnated graphene aerogel for desalination and photodegradation of contaminants for use in the disclosed system is also disclosed herein. The nanofiber-impregnated graphene aerogel exhibits excellent hydrophilicity, thermal insulation, and photodegradation capability, and allows for efficient solar-powered evaporation of water. The introduction of photocatalytic nanofibers into the graphene aerogel allows effective interfacial evaporation and in situ photodegradation of contaminants. The rate of water evaporation is preferably greater than 1.3 gal/ft2 per day, and the contaminant removal is preferably greater than 90%. A method of desalinating and purifying water using the disclosed system is also disclosed herein.

Abstract: An electrospun polymer nanofibrous membrane that provides high filtering efficiency and excellent porosity is disclosed herein. The membrane may be treated with one or more antimicrobial or antiviral agents. The treatment may preferably be a coating of one or more antiviral agents on the surface of the membrane. Alternatively, one or more antiviral agents may be impregnated into the membrane. The membrane may additionally or alternatively be impregnated with one or more metal-organic frameworks (MOFs). The membrane has a high filtering efficiency and sufficient porosity to provide breathability characteristics. In some embodiments, the membrane is suitable for use in making facemasks and respirators that are highly resistant to infectious pathogens and/or other small particulates. In some embodiments, the membrane is suitable for use in HVAC applications. In some embodiments, the membrane is suitable for use in removal of VOCs and CO2 in conjunction with a carbon nanofiber membrane.
