This book gives comprehensive information on the design, preparation and application of organic-inorganic composite membranes that are used for molecular separation. Various membrane types with different materials are highlighted, including polymer/ceramic composite membranes, mixed matrix membranes, metal-organic frameworks membranes and graphene-based membranes. Physical and chemical properties, morphologies, interfacial behaviors, transport characteristics and separation performance of the organic-inorganic composite membranes are thoroughly discussed based on advanced characterization techniques.Meanwhile, the book contains several typical applications of the membranes in fields such as bio-fuels production, organic compounds recovery, solvent dehydration, carbon dioxide capture and others. In addition, large-scale production and industrial implementation of the organic-inorganic composite membranes are briefly introduced.

Solubility-based membrane separation, in which the more soluble species preferentially permeates across the membrane, has attracted considerable recent attention due to both economic and environmental concerns. This solubility-selective mode is particularly attractive over a diffusivity-selective mode in applications in which the heavier species are present in dilute concentrations. Examples include the recovery of volatile organic components (VOCs) from effluent streams and the removal of higher hydrocarbons from natural gas. Recently, nanocomposites have shown great promise as possible membrane materials for solubility-selective separations. The chemical derivatization of inorganic mesoporous substrates has been explored to synthesize organic-inorganic nanocomposite membranes. The most exciting feature of this approach is that it enables the rational engineering of membrane nano-architecture with independent control over the free volume and chemistry to create membranes with highly customizable permselectivity properties. In this study, we synthesized the organic-inorganic nanocomposite membranes by decorating the surfaces of commercially available mesoporous alumina substrates, and surfactant-templated highly ordered mesoporous silicate thin films placed on commercially available macroporous inorganic substrates, with a selective organic material that is physically or chemically anchored to the porous surfaces. Hyperbranched melamine-based dendrimers, with nanometer dimension and chemical composition designed to target certain components, were used as filling agents. We evaluated these membranes for several environmentally relevant separations, such as the recovery of the higher hydrocarbon from air and the removal of trace VOCs from air or water, while exploring the impact of organic oligomer size, chemistry, and surface coverage, as well as substrate pore size and structure, on membrane performance. First, we did a model study to verify the feasibility of dendrimer growth inside mesopores by using ordered mesoporous silica. Alumina-ordered mesoporous silica (alumina-OMS) hybrid membranes were prepared as new inorganic porous substrates. Finally, we synthesized dendrimer-ceramic nanocomposite membranes by growing several generations of melamine-based dendrimers with diverse functional groups directly off the commercial alumina membranes. Composite membranes show very high propane/nitrogen selectivity up to 70.

This book aims at illustrating several examples of different membrane compositions ranging from inorganic, polymeric, metallic, metal organic framework, and composite which have been successfully deployed to separate industrially relevant gas mixtures including hydrogen, nitrogen, methane, carbon dioxide, olefins/parafins among others. Each book chapter highlights some of the current and key fundamental and technological challenges for these membranes that must be overcome in order to envision its application at industrial level.

The development of a new class of nanocomposite membranes has served as one of the most prominent strategies to address the intrinsic limitations of conventionally used polymeric and inorganic membranes. Nanocomposite membranes consist of nanosized inorganic nanomaterials that are incorporated into the structure of continuous polymer matrices. Owing to the exceptional properties exhibited by the nanomaterials, the resultant nanocomposite membranes demonstrate higher selectivity and permeability that surpass the Robeson upper boundary limit. Nanocomposite Membranes for Gas Separation provides a comprehensive review of the advances made in the development and application of gas separation nanocomposite membranes. In particular, the book covers the focuses on the fabrication, modification, characterization and applications of nanocomposite membranes for gas separation. It is an important reference source both for materials scientists, environmental engineers and chemical engineers who are looking to understand how nanocomposite membranes are being used to create better techniques for gas separation. Provides detailed insights in the fabrication, modification, characterization and applications of nanocomposite membranes for gas separation Shows how nanotechnology is being used to address current limitations of the development of polymeric and inorganic membranes for gas separation, including low separation performance in terms of permeability and selectivity Explores the potential of nanocomposite membranes to help create more effective gas separation techniques
