Interfacial adhesion between polymer separation layer and ceramic support for composite membrane

An in situ characterization method for mechanical and adhesive properties of organic/ceramic composite membranes is built on the basis of nanoindentation technique in this work. The polydimethylsiloxane (PDMS) was used as the separation layer with the support of porous ZrO 2 /Al 2 O 3 ceramic tubes. The effects of roughness of the ceramic support and the viscosity of PDMS solution on the mechanical properties of the PDMS separation layer and the interfacial adhesion at the interface were investigated in detail. It was found that when the roughness of the ceramic support increased and the viscosity of PDMS solution decreased, the interfacial adhesion strength of PDMS/ceramic composite membrane increased, but these two variables had little effect on the mechanical properties of the PDMS separation layer. Our results indicate that the mechanical interlocking dominates the adhesion between the PDMS separation layer and the porous ceramic support. V

“…Polymer-ceramic composite membranes characterized with superior combinations of structural integrity, fouling resistance, flux and selectivity have been reported for the ultrafiltration (UF) [1][2][3] and pervaporation (PV) [4][5][6][7][8] applications. These membranes constitute a polymer skin layer consisting of polysulfone [2], styrene acrylonitrile [3], polyvinyl acetate (PVAc), polyvinyl pyrrolidone (PVP) [4], cellulose acetate (CA) [5], polydimethylsiloxane (PDMS) [8,9] and ceramic supports with nominal pore sizes of 200-2000 nm made from kaolin [3], alumina [4] and zirconia [9].…”

“…The growth of the CA top layer was anticipated after the formation of the intermediate layer. CA top layer growth rate was also largely dependent on the CA concentration in the solution, structure and morphology of the intermediate layer 18,19 . Thus, the increase of the polymer layer on the ceramic support is an important mechanism that influences in the heterogeneity of selective layer and in the distribution of pore size.…”

In this study, polymer/ceramic composite membranes were prepared and characterized. The polymer used was polyamide 66 (PA66) deposited by dip coating on the inner surface of α-alumina-based (Al 2 O 3 ) microporous tube. A coating on the ceramic support surface and the formation of the selective layer was analyzed by scanning electron microscopy (SEM) in membranes with one (PA-1) and two layers (PA-2). The results of mercury porosimetry showed that the deposition of the polyamide layers decreases the average pore size. The PA-1 presented an average pore size of 0.35 μm, while the PA-2 presented two peaks of 0.18 and 0.56 μm. Both showed a superior performance than the ceramic support (pore diameter of 0.65 μm). Although, the permeate flux was higher with an impregnation membrane, the number of layers (one or two) just introduced a slight difference in pore statistical analysis. The order of rejection coefficient values for protein molecules is BSA > egg albumin > trypsin. The permeation tests showed that the composite membrane can be applied in ultrafiltration processes with MWCO of 69 kDa.
