Mixed matrix membranes are prepared from zeolites and polymers, such as polyimides, in a void free fashion where either no voids or voids of less than several Angstroms are present at the interface of the polymer and the zeolite by bonding (hydrogen, ionic, or covalent) functional groups on the zeolite with functional groups on the polymer.

Hollow filler based mixed matrix membranes
Chemical Communications, 2010Micron-sized hollow spheres with zeolitic shell were used as inorganic fillers in PDMS-based mixed matrix membranes, overall enhancing solvent permeabilities as compared to traditional zeolite fillers, while selectivities were maintained.

Mixed matrix membrane development
Membrane Technology, 2002Abstract: Two types of mixed matrix membranes were developed by UOP in the late 1980s. The first type includes adsorbent polymers, such as silicalite‐cellulose acetate (CA), NaX‐CA, and AgX‐CA mixed matrix membranes. The silicalite‐CA has a CO2/H2 selectivity of 5.15 ± 2.2. In contrast, the CA membrane has a CO2/H2 selectivity of 0.77 ± 0.06.

Mixed-matrix membrane adsorbers for protein separation
Journal of Chromatography A, 2003The separation of two similarly sized proteins, bovine serum albumin (BSA) and bovine hemoglobin (Hb) was carried out using a new type of ion-exchange mixed-matrix adsorber membranes. The adsorber membranes were prepared by incorporation of various types of Lewatit ion-exchange resins into an ethylene-vinyl alcohol copolymer porous structure.
