Embodiment Construction

[0057] definition

[0058] The following terms used throughout the specification and claims are defined as follows:

[0059] "Amphiphilic" means a molecule that has both solvent preference and solvent exclusion regions.

[0060] "Hydrophilic" means that water is preferred. The hydrophilic compound and the surface have high surface tension.

[0061] "Hydrophobic" means water repellent. The hydrophobic compound and the surface have low surface tension.

[0062] "Surfactant" means a type of amphiphile having at least one hydrophilic region and at least one hydrophobic region. A system designed to work with surfactants is likely to work with all amphiphiles.

[0063] "Phospholipid" means the main component of cell membranes. These molecules self-assemble into vesicles in water and exist in a dispersed phase in a low surface tension solvent.

[0064] "Layered" means containing multiple layers or bilayers.

[0065] "Mesogenic phase" means a surfactant liquid crystal structure formed by the i...

Abstract

Stabilized surfactant-based membranes and methods of manufacture thereof. Membranes comprising a stabilized surfactant mesostructure on a porous support may be used for various separations, including reverse osmosis and forward osmosis. The membranes are stabilized after evaporation of solvents; in some embodiments no removal of the surfactant is required. The surfactant solution may or may not comprise a hydrophilic compound such as an acid or base. The surface of the porous support is preferably modified prior to formation of the stabilized surfactant mesostructure. The membrane is sufficiently stable to be utilized in commercial separations devices such as spiral wound modules.

Description

[0001] Cross references to related applications [0002] This application requires the U.S. Provisional Patent Application Serial No. 61, entitled "Self Assembly of Hierarchical and / or Multiscale Materials Via Physical Confinement" filed on May 21, 2010 / 347,317 and the United States Provisional Patent Application Serial No. 61 / 415,761 filed on November 19, 2010, entitled "Free Standing Heirarchically Self Assembled Films" and the rights of application. Their description and claims are incorporated herein by reference. Background of the invention [0003] Invention Field (Technical Field): [0004] Embodiments of the present invention employ biomimetic multi-scale self-assembled bodies and materials, such as membranes manufactured therefrom, which are manufactured in different configurations using batch and automated manufacturing to enable aqueous separation and solute concentration. Embodiments of the present invention also relate to a method of multi-scale self-assembly and mate...
