  • Lyotropic liquid crystal nanofiltration membranes
    Patent number: 7604129
    Abstract: The invention provides composite nanofiltration membranes (FIG. 5) with lyotropic liquid crystal (LLC) polymer porous membranes (30) attached to a porous support (20). The LLC membranes are prepared from LLC monomers which form the inverted hexagonal or bicontinuous cubic phase. The arrangement, size, and chemical properties of the pores can be tailored on the molecular level. The composite membrane of the invention is useful for separation processes involving aqueous and nonaqueous solutions as well as gases. Methods for making and using the composite nanofiltration membranes of the inventions are also provided.
