  • Microfiber supported nanofiber membrane
    Patent number: 7591883
    Abstract: A nanofiber membrane is formed on a microfiber membrane. The nanofiber membrane may be electro sprayed directly onto the microfiber membrane and becomes integrated with the microfiber membrane to form a filter. The microfiber membrane provides structural integrity to for the nanofiber membrane, and an additional microfiber membrane may be added to sandwich the nanofiber membrane.
    Type: Grant

  • Self-cleaning filtration nanofiber membrane
    Publication number: 20070151921
    Abstract: A self-cleaning membrane is formed of microfibers and/or nanofibers that contain functionalized nanoparticles. In one embodiment, the nanoparticles contain photo-catalytic particles, that when exposed to ultraviolet light, cause decomposition of organic molecules. The decomposed molecules may be easily flushed from the membrane. In one embodiment, the particles are titania nanoparticles, some of which are disposed on or near the outside of the fibers.
