  • Asymmetric Nanotube Containing Membranes
    Publication number: 20110290730
    Abstract: This invention relates to heterogenous pore polymer nanotube membranes useful in filtration, such as reverse osmosis desalination, nanofiltration, ultrafiltration and gas separation.
    Type: Application
    Filed: August 8, 2011
    Publication date: December 1, 2011
    Applicant: NanOasis Technologies Inc.
    Inventors: Timothy V. Ratto, Jason K. Holt, Alan W. Szmodis
  • Membranes With Functionalized Carbon Nanotube Pores For Selective Transport
    Publication number: 20110220574
    Abstract: Provided herein composition and methods for nanoporous membranes comprising single walled, double walled, or multi-walled carbon nanotubes embedded in a matrix material. Average pore size of the carbon nanotube can be 6 nm or less. These membranes are a robust platform for the study of confined molecular transport, with applications in liquid and gas separations and chemical sensing including desalination, dialysis, and fabric formation.

  • Membranes with embedded nanotubes for selective permeability
    Patent number: 7993524
    Abstract: Membranes for filtration by size exclusion are formed from open-ended nanotubes embedded in a polymeric matrix. The matrix forms a layer whose thickness is substantially less than the average length of the nanotubes, allowing the nanotubes to be randomly oriented throughout the matrix while providing channels extending through the layer for the selective passage of molecular species or particles based on size.
    Type: Grant
