Studies on the meso-sized selectivity of a novel organic/inorganic hybrid mesoporous silica membrane

Highly hydrophilic poly(vinylidene fluoride)/meso-titania hybrid mesoporous membrane for photocatalytic membrane reactor in water

“…During the past decade, lots of novel hybrid mesoporous membranes composed of mesoporous materials, such as meso-silica or meso-titania, not on the surface but within the inside-pores of some porous membranes have attracted great attention due to their unique structure with pores-in-pores 1 2 3 4 , and widely potential applications in the templated-syntheses of nanomaterials 5 6 , nanofiltration 7 8 9 10 , sensors 11 12 13 , electronic devices 14 and lithium batteries 15 . Normally, dual templates including various porous membranes and surfactants have been respectively employed as the morphology-directing hard template and the structure-directing soft template in the synthesis of hybrid mesoporous membranes.…”

“…So far, all of those reports on hybrid mesoporous membranes have mainly focused on two kinds of commercial filtration membranes with one-dimensional cylindrical channels, namely porous anodic alumina (PAA) 1 2 3 4 5 6 7 16 and polycarbonate (PC) membranes 8 11 17 , both of which were applied as the hard templates. Recently, other commercial porous membrane with different structure and property, such as cellulose and polyethylene terephthalate membranes, have also been used as the new hard templates for the fabrication of hybrid mesoporous membrane by Yamauchi et al 9 and our group 10 12 . However, it should be noted that all the hard templates mentioned above are hydrophilic membranes.…”

Decorating soft electrified interfaces: From molecular assemblies to nano-objects

“…Porous polyethylene terephthalate (PET) membrane were modified with mesoporous silica via aspiration induced infiltration method which is a modification of soft templated solgel process performed under acidic conditions [195]. Resulting silica mesopores were found to grow along the preformed macropores of a PET membrane as depicted on Figure 10B.…”

“…Examples of an ex situ prepared membrane: (A) SEM images of a silicate membrane grown on a mercury surface (Adapted from ref. [190] and (B) SEM image of pores within polyethylene terephthalate (PET) membrane filled with mesoporous silica (Adapted from [195]). Cyclic voltammograms on part (C) show the effect of zeolite membrane on potential window recorded in the absence and in the presence of zeolite membrane.…”

Polysulfone(PSF) composite membrane with micro-reaction locations (MRLs) made by doping sulfated TiO 2 deposited on SiO 2 nanotubes (STSNs) for cleaning wastewater

“…Facing the problems above, various approaches such as chemical grafting, surface modification, doping hydrophilic polymers [4][5] and nano-inorganic particles [6][7][8] into casting solutions have been developed in the past years. Especially, the strategy of doping inorganic oxide particles into polymers to prepare organic-inorganic composite membranes is extremely fascinating due to its simple operation process and having the advantages of both organic membranes and inorganic particles.…”
