Removal of viruses from their cocktail solution by liquid-crystalline water-treatment membranes

Liquid-crystalline (LC) water-treatment membranes obtained by in situ photopolymerization of ionic mesogenic monomers have been shown to efficiently remove viruses. In our previous works, bicontinuous cubic (Cub(bi)) and smectic (Sm) LC membranes prepared from ionic taper- and rod-shaped polymerizab...

Sumario:Liquid-crystalline (LC) water-treatment membranes obtained by in situ photopolymerization of ionic mesogenic monomers have been shown to efficiently remove viruses. In our previous works, bicontinuous cubic (Cub(bi)) and smectic (Sm) LC membranes prepared from ionic taper- and rod-shaped polymerizable mesogens, respectively, were used for this purpose. Here, we report the results of virus removal by columnar (Col) LC water-treatment membranes having ionic nanochannels obtained from ionic taper-shaped mesogens. These effects are compared with those obtained for Cub(bi) membranes. The effects of these Col and Cub(bi) LC ionic membranes on the removal of several viruses from their cocktail solution are also examined.
