在这里，我们报告了柱状液晶（LC）纳米结构膜，高度去除病毒，并显示出足够的水渗透。这些膜是通过采用表现出四元柱相的双组分液晶来制备的。膜的病毒截留率>99.99%（log（10）reduction value（LRV）> 4），水通量为19 ~ 61 L m（-2）h（-1）（操作压力：0.3 MPa）。这些膜是通过扇形二醇分子和咪唑离子液体混合物的光聚合，然后随后除去离子液体来制造的。截留率和水通量取决于离子液体的分数。这些结果显示了用于去除病原体和污染物的水处理纳米结构膜的材料的新设计策略。
Here we report columnar liquid-crystalline (LC) nanostructured membranes that highly remove viruses and show sufficient water permeation. These membranes were prepared by employing two-component liquid crystals that exhibit tetragonal columnar phases. The membranes exhibited virus rejection values of >99.99% (log(10) reduction value (LRV) > 4) and water flux ranging from 19 to 61 L m(-2) h(-1) (operation pressure: 0.3 MPa). These membranes were fabricated by photopolymerization of a fan-shaped diol molecule and imidazolium ionic liquid mixture, followed by subsequent removal of the ionic liquid. The rejection values and water flux depend on the fraction of ionic liquid. These results show new design strategies of materials for the water treatment nanostructured membranes that remove pathogens and contaminants.
