eng Abstract:
In the current work, we have considered and compared the deposition on the surface of ceramic membrane of the polysiloxane layers with different functional groups, such as ≡Si(CH2)3SH, ≡Si(CH2)3NH2, and ≡Si(CH2)2P(O)(OH)2, and ≡Si(CH2)3NHC(S)NHC2H5. We have also reported the fabrication of ceramic membranes with bifunctional polysiloxane surface layers, containing two types of complexing groups of different nature, or (fluoro)alkyl groups along with complexing groups. Tetraethoxysilane and bis(triethoxy)silane structuring agents were used in the study. The identification of the deposited layers on the membrane surface was carried out by IR spectroscopy. It was shown by SEM, that the functionalized layers themselves are usually formed by 50-70 nm nanoparticles and their porous structure depends on several fabrication factors.
