Porous organic polymer embedded thin-film nanocomposite membranes for enhanced nanofiltration performance

Porous organic polymers have been considered promising for the design of high performing membranes, mainly because of their superior surface area, intrinsic mesoporous structure and good polymer affinity. In this study, hierarchical o-hydroxyazo porous organic polymers (o-POPs) and piperazine (PIP) monomers were incorporated into the casting solution, followed by phase inversion to prepare PIP-containing polymeric substrates. The o-POPs modified...
