제목 Ultrathin Nanomesh-Structured Membranes Based on Unidirectional Alignment of Engineered M13 viruses
초록 With the increasing development in membrane technology, ultrathin membranes have received much attention due to their advantages, such as much higher permeability even applying lower pressure or a substantial reduction in filtrate loss as compared to conventional membranes. However, these ultrathin nanostructured membranes have been required to meet conditions of higher mechanical strength and narrow pore size distribution. In this study, we present a novel means of fabricating the ultrathin nanomesh-structured membranes with high filtration performances and mechanical durability. To fabricate 3D-stacked and mesh-structured membranes, we employ unidirectional alignment of the one-dimensional M13 viruses via applying controlled shear forces and then transferred it as a stack to have alternate perpendicular orientations. In addition, the filtration flux and rejection characteristics of virus-templated membranes are controlled by stacking numbers of the unidirectionally aligned viruses.
