The aim of this research is to study effect of different solvents on the membrane morphology and on the performance of zeolite-filled composite pervaporation membranes. PAN (polyacrylonitrile) was used as a base polymer and zeolite 13x (32 wt.%) was used as the filler. The solvents considered were DMF (dimethyl formamide), DMSO (dimethyl sulfoxide), DMAc (dimethyl acedamide) and THF (tetrahydrofuran). The cross-sectional morphology of manufactured membranes shows three layers: a zeolite-free polymer layer, a zeolite-filled polymer layer and a skin layer. However, at the same casting content (5.4% PAN, 2.6% zeolite 13x, 92 wt.% solvent) the ratio of the thickness of these layers to total membrane thickness varies with the solvent used. The most homogeneous zeolite distribution in the polymer network is obtained with solvent DMSO.

The performance of polyethersulfone nanocomposite membrane in the removal of industrial dyes
Mahmoudian, Mehdi; Ghasemıkouchameshgı, Mahmoud (2021-05-14)
In the present study, graphene oxide was functionalized by hyperbranched epoxy and then used as an additive in the polyethersulfone membrane. The process of preparation and characterization of the synthesized hyperbranched epoxy, and graphene oxide modification was investigated by some analysis such as XRD, EDAX, FTIR, NMR, and TGA. Morphology of modified nanostructures, their distribution in the membrane matrix, and morphology of membranes were evaluated by TEM, FESEM analysis. Experimental results showed ...
Effect of solvent choice on cellulose acetate membrane fabrication by phase inversion and deacetylation by alkaline hydrolysis
Tekin, Fatma Seden; Çulfaz Emecen, Pınar Zeynep; Department of Chemical Engineering (2022-8)
In this study, the effect of solvent choice on cellulose acetate (CA) membrane morphology and performance was investigated to relate this to the thermodynamics and kinetics of phase inversion. Three different solvent systems were used, which are dimethyl sulfoxide (DMSO), the mixture of DMSO: acetone (DA) and DMSO: acetic acid (DHAc) in the ratio of 1:1. Water was used as non-solvent. Acetone and acetic acid were chosen due to their similar solvent quality for cellulose acetate based on Hansen solubility pa...
The frictional contact problem of sliding rigid parabolic stamps on graded materials
GÜLER, MEHMET ALİ; Erdogan, F.; Dağ, Serkan (2006-10-18)
This study presents an analytical procedure to determine the contact stress distribution at the surface of an FGM coating perfectly bonded to a homogeneous substrate. The coating is assumed to be loaded by a rigid stamp of a semi-circular or circular profile. Using Fourier transformations, the contact mechanics problems are reduced to a singular integral equation of the second kind. Singular behavior of the unknown contact stress distribution at the end points is determined by following a function theoretic...
The Effect of Ultrasonication on the Size and Morphology of Iron Oxide - Chitosan Nano and Microparticles
Akin, Deniz; YAKAR, ARZU; Gündüz, Ufuk (2013-04-28)
The aim of this study is to synthesize magnetic Fe3O4-chitosan nano and microparticles (Fe3O4-CPs) by suspension cross-linking and ionic gelation methods and investigate the effect of ultrasonication on the size, morphology and magnetic properties. The synthesized particles were characterized by transmission electron microscopy (TEM), dynamic light scattering (DLS) and vibrating sample magnetometry (VSM). The results showed that the ultrasonication decreased the mean particle diameter and enhanced magnetic ...
Effect of preparation parameters on performance of dense homogeneous polycarbonate gas separation membranes
Hacarlioglu, P; Toppare, Levent Kamil; Yılmaz, Levent (Wiley, 2003-10-17)
The aim of this study is to determine the effect of preparation parameters on the membrane permeation mechanism and separation performances of dense homogeneous poly(bisphenol A carbonate) (PC) membranes. Blade-casting and drop-casting techniques are used for casting films from solutions with varying concentrations. Chloroform and methylene chloride are used to determine the effect of the properties of the casting solvent. Permeation measurements are done with Ar, N-2, O-2, CH4, CO2, and H, gases. The selec...
