“…Polydimethylsiloxane is an important polymer used in many engineering areas from electronics, sensor, and adhesive applications to membrane and biomedical applications. However, as PDMS has a high chain mobility resulting from its flexible structure, it gives low values of membrane selectivity (Senol, 2021;Kilic, 2021). For this reason, filled PDMS films were prepared using zeolite NaY, zeolite 5A and nanosized TiO2 to combine the properties of different inorganic materials and polymer.…”

The pervaporation method in which the transport mechanism through a nonporous membrane is explained by the solution-diffusion model can be used for the separation of water-organic and organic-organic mixtures. The sorption behaviour of a polymeric membrane plays important role in membrane transport, depending on the solvent and polymer properties. Since the membrane itself is the key component in the pervaporation method, as with all other membrane processes, it is necessary to determine suitable membrane material that can selectively separate at least one component from a liquid mixture. Ethanol, butanol and acetone are widely used in many industrial applications. PDMS is one of the polymers that is frequently used in the recovery of organics from organic-water mixtures or the separation of organic-organic mixtures. PDMS gives high chain mobility, low mechanical resistance and low selectivity values. For this reason, its properties need to be improved. In this study, unfilled PDMS, PDMS/TiO2, PDMS/NaY and PDMS/5A mixed matrix films were prepared, and the sorption behaviours of prepared PDMS films in different chemical substances at temperatures of 30,40 and 50°C were investigated.

“…Therefore, its structural properties need to be improved in order to control adsorption and membrane swelling (Tanaka, 2010). The incorporation of inorganic materials such as zeolite into the polymer matrix can improve membrane performance (Senol, 2021;Kilic, 2021).…”

“…The zeolite thin film/membranes are among inorganic membranes which consist of hydrated crystalline aluminosilicates with open three-dimensional framework structures, made up of SiO 4 and AlO 4 tetrahedrons linked by sharing their oxygen atom to form regular intracrystalline cavities and channels of atomic dimensions. The research of zeolite thin film/membrane is an attractive topic of inorganic membrane technology due to their various applications, such as gas or liquid separation [ 1 , 2 , 3 , 4 , 5 ], chemical sensors [ 6 , 7 , 8 ], catalytic membrane [ 9 , 10 ], dielectric thin films [ 11 , 12 ], corrosion-resistant coatings [ 12 , 13 ] and biological application [ 14 ].…”

Silicalite-1 thin film was prepared with the following batch composition—3TPAOH:25TEOS:1450H2O:100EtOH—and synthesized using the hydrothermal technique. Silicalite-1 colloidal crystals were successfully coated on the surface of the silica substrate by the dip-coating method. The investigation of silicalite-1 thin film with organic structure-directing agents (SDA), using a seeding technique with various colloidal seed concentrations, number of dip-coating steps, and crystallization time, were systematically discussed and obtained interesting results. Silicalite-1 powder and Silicalite-1 membrane, the patterns of which showed a unique characteristic crystallography of MFI topology, were characterized by XRD, which indicated the preferred orientation along the b-axis perpendicular to the substrate surface. The morphology and crystal size aspect of Silicalite-1 were also examined by a scanning electron microscope (SEM).
