Oxygen permeation through functionalized hydrophobic tubular ceramic membranes

Controlling of water wettability by structural and chemical modification of porous anodic alumina (PAA): Towards super-hydrophobic surfaces

“…For example Al 2 O 3 membranes with surface modified by silanization reactions were used to improve oxygen selective mass transfer and inhibit water loss [35]. Hydrophobic alumina membranes prepared by surface modification with perfluoroalkanoic acids demonstrated excellent selectivity for organic compounds [36].…”

Development of bubble-less ozonation and membrane filtration process for the treatment of contaminated water

“…Four different hydrophobic polymers were investigated in this work for modifying the surface of ceramic membranes; 1,2-dipalmitoyl-sn-glycero-3-phosphocholine (C 40 H 80 NO 8 P, 99% purity), trichloromethylsilane (CH 3 SiCl 3 , 97% purity), methyldiethoxysilane (C 5 H 14 O 2 Si, 96% purity) and octadecyltrimethoxysilane (CH 3 (CH 2 )17Si(OCH 3 ) 3 , 90% purity) [27][28][29]. The precursors were obtained from Sigma-Aldrich and their chemical structures are illustrated in Fig.…”

Nano-structured surface modification of micro-porous ceramic membrane with positively charged nano-Y2O3coating for organic dyes removal

“…9 And compared with electrically neutral membrane, charged ceramic membrane refers to the inorganic micro-porous ceramic membrane with a positive or negative charge on its internal surface, which possesses obviously technical advantage for electrical property. 12 This is because that charged ceramic membrane could achieve pollution resistance [13][14][15] by electrostatic repulsion, and it removes vanishingly small size of particles with the opposite charges through electrostatic adsorption. 12 This is because that charged ceramic membrane could achieve pollution resistance [13][14][15] by electrostatic repulsion, and it removes vanishingly small size of particles with the opposite charges through electrostatic adsorption.…”
