The preparation and application of a low-cost multi-channel tubular inorganic–organic composite microfiltration membrane

Hierarchical structure control of MgAl2O4 porous ceramics and application to organic polymer filtration membrane

“…Modeling of infiltration of liquids in porous media is a well-studied subject, especially in the field of hydrology where it is used to model seepage of water through porous soils and rocks. 29,30 The physics of resin flow into a mold under pressure is similar to the seepage problem and so similar approaches have been used also to model the flow of resin into a mold containing fiber mats. 23,[31][32][33][34][35][36][37][38] The models are used in these cases to determine the resin flow front and mold filling times corresponding to different infiltration conditions.…”

“…Li et al 30 prepared a multi-channel tubular inorganicorganic composite microfiltration membrane composed of a commercial α-Al 2 O 3 tube with poly(vinylidene fluoride)/cellulose acetate (PVDF/CA) blend as a separation layer. They reported that the microfiltration membrane (pore size: 22.2 nm and porosity: 70.7%) separated PEO with m.w.…”

“…Their filtration performance was investigated by removing 1 million molecular-weight polyethylene oxide (PEO) from water. [26][27][28][29][30] PEO is now used in manufacturing advanced devices, such as polymer electrolyte in lithium ion batteries, [31][32][33][34] and removal/concentration of PEO in waste water is favorable for a better environment. 1 shows the schematic illustration of sample preparation procedure.…”
