Applications of Zeolite Membranes and Films

Zeolites are traditionally used in catalysis/purification and separation applications in the petrochemical industry but are rapidly finding new uses. This section discusses membranes for low-dielectric-constant, corrosion-resistant, hydrophilic and antimicrobial, and pervaporation applications. 

Low-dielectric-constant (low-fc) materials are needed to reduce signal delays, crosstalk noise, and power consumption in the next generation of faster and more powerful 

They successfully prepared pure-silica zeolite (PSZ) MFI films by in-situ, seeded growth, and spin-on methods. b-Oriented in-situ films yielded k values of 2.7 and elastic modulus (E) values of 30-40 GPa.[1521 Spin-on MFI films that incorporated y-cyclodextrin 

Zeolite coatings have been investigated as corrosion-resistant coatings for aluminum alloys in aerospace applications. The currently used chromic acid anodization and chromate conversion coatings are effective but release hexavalent chromium, which is 

Hydrophilic and antimicrobial zeolite coatings have also been shown to be effective for gravity-independent water-separation applications on manned spacecraft. Condensing
