Permeation models for mixed matrix membranes

Journal of Colloid and Interface Science, 2008
Permeation models for mixed matrix membranes (MMMs) are discussed. A new model is proposed for the effective permeability of a species in MMMs. The model takes into account the presence of interfacial layer (shell) at the surface of the core filler particles.

New generation mixed matrix membrane for CO2 separation: Transition from binary to quaternary mixed matrix membrane

Chemosphere
Contemporary advances in material development associated with membrane gas separation refer to the cost-effective fabrication of high-performance, defect-free mixed matrix membranes (MMMs). For clean energy production, natural gas purification, and CO2 capture from flue gas systems, constituting a functional integration of polymer matrix and inorganic ...

Polymeric and mixed matrix polyimide membranes

Separation and Purification Technology, 2014
Three different polyimide type polymers were used to prepare porous asymmetric membranes by non-solvent induced phase separation (NIPS): a homopolymer (Matrimid) and two co-polymers (P84 and Torlon). The effect of the casting solvent on membrane morphology and transport properties was studied.

Solvent-resistant P84-based mixed matrix membrane adsorbers

Separation and Purification Technology, 2011
This work reports new mixed matrix hollow fiber membranes for adsorption of biomolecules from organic solvents. The membranes are composed of polyimide P84, the porous matrix forming polymer, and cation exchange particles incorporated in this matrix. These macroporous membranes, having homogenous structure with a uniform distribution of particles, are ...

Ribbed PVC–silica mixed matrix membranes for membrane bioreactors

Journal of Membrane Science, 2016
Abstract The feasibility of ribbed-PVC–silica mixed matrix membranes (MMM) in a membrane bioreactor (MBR) application was investigated. Three operational aspects were evaluated: inclusion of vibration, use of relaxation (cycle time), and optimization of the cleaning procedure.

Polycarbonate–polypyrrole mixed matrix gas separation membranes

Journal of Membrane Science, 2003
Abstract The gas separation properties of the polycarbonate–polypyrrole mixed matrix membranes were evaluated based on the introduction of conducting polymer as powder fillers. The electrically conductive fillers are obtained from two main synthesis routes namely electrochemical and chemical methods.

PIM-1/graphene mixed matrix membranes

2014
The award of the 2010 Nobel Prize in Physics to Andre Geim and Kostya Novoselov at the University of Manchester focused attention on the unique properties of graphene. A little before the groundbreaking experiments in graphene were reported in 2004,1 the first membrane-forming Polymer of Intrinsic Microporosity (PIM), commonly referred to as PIM-1, was
