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) 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 membranes. The effects of these Col and Cub LC ionic membranes on the removal of several viruses from their cocktail solution are also examined.
通过离子介晶单体的原位光聚合制备的液晶（LC）水处理膜已被证明能有效去除病毒。在我们之前的工作中，分别由离子锥形和棒状可聚合介晶体制备的双连续立方（Cub）和近晶（Sm）LC膜被用于此目的。在此，我们报告了由离子锥形介晶体制备的具有离子纳米通道的柱状（Col）LC水处理膜去除病毒的结果。将这些结果与Cub膜的结果进行比较。还研究了这些Col和Cub LC离子膜对从其混合溶液中去除几种病毒的效果。
