    摘要: Asymmetric organic-inorganic films and methods for forming and using such films. For example, the films are used as membranes for selective separation applications. The methods combine co-assembly of block copolymer (BCP) and inorganic nanoparticles (NPs), such as, for example, titanium dioxide (TiO 2 ), with non-solvent induced phase separation. The resulting films exhibit structural asymmetry. For example, the films have a thin nanoporous surface layer on top of a macroporous finger-like support layer. Parameters that may dictate membrane morphology include the fraction of inorganic nanoparticles used and the length of time allowed for surface layer development. In filtration tests, the resulting membranes show both desirable selectivity and permeability. The synthesis methods for hybrid membranes provide a new self-assembly platform upon which multi-functional and high-performance organic-inorganic membranes can be formed.

    摘要: This invention relates to an asymmetric composite membrane containing a polymeric matrix and carbon nanotubes within a single membrane layer, where the carbon nanotubes are randomly oriented within the polymeric matrix and the composite membrane is formed by phase inversion. This invention also relates to a method for producing the composite membrane which includes: coating a surface with a film of a polymer solution containing a polymeric matrix and carbon nanotubes dissolved in at least one solvent; immersing the coated surface in a non-solvent to affect solvent/non-solvent demixing resulting in phase inversion to form a carbon nanotube-containing membrane; and optionally, removing the carbon nanotube-containing membrane from the surface. The invention also relates to a desalination method using the composite membrane.
