Preparation of high flux organic solvent nanofiltration membrane based on polyimide/Noria composite ultrafiltration membrane

Preparation, modification and antifouling properties of polyaniline conductive membranes for water treatment: a comprehensive review

“…NIPS, also known as the phase inversion method, relies on the principle that a polymer-containing solvent has higher solubility when in contact with another non-solvent phase to achieve membrane formation. [69][70][71][72][73] Due to diffusive exchange between the solvent and the non-solvent phase, the prepared membranes usually show asymmetric structures. The top of the membrane generally exhibits a homogeneous and dense structure due to hydrophilic diffusion of the functional material, while the bottom forms a finger-like or spongy structure (Fig.…”
