Abstract
The further advancement of membrane separation processes will require the development of more selective membranes. In this study, membranes that take inspiration from the mosaic structure of cell walls and use multiple functionalities of unique chemical design to control solute transport through chemical factors as well as steric factors are detailed. Specifically, a poly{acrylonitrile-co-[oligo(ethylene glycol) methyl ether methacrylate]-co-(3-azido-2-hydroxypropyl methacrylate)} copolymer tailor-made for the generation of nanofilters, which possess a high density of well-defined pores that are lined by azido moieties, allowed for the generation of chemically patterned mosaic membranes in a rapid manner through the use of printing devices. By engineering the composition of the reactive ink solutions printed on the membrane to allow for the rapid, one-to-one covalent attachment of alkynyl-functionalized groups to the azido moieties, we generated large areas of patterned membranes in seconds rather than ho...
