Effects of linking group on the desalination performance of three-dimensional covalent organic framework membranes

Recent advances of pure/independent covalent organic framework membrane materials: preparation, properties and separation applications

“…21,83 Therefore, the preparation of membranes using hydrophilic COF is beneficial for membrane separation. For example, Guan 84 et al investigated the effect of three different linking groups on the desalination performance of COF membranes. They compared the –C group, –Ad group and –Si group and found that the presence of the –Si group resulted in better hydrophilicity of the COF membranes, which is a result of the better bonding ability of the –Si group relative to the other two groups.…”
