N2 - ZIF-8 and ZIF-67 particles, with sizes of 70 ± 10 nm and 240 ± 40 nm, respectively, were deposited by dip-coating on top of polyimide P84® asymmetric supports. In the best conditions, this gives rise to a MOF (metal-organic framework) monolayer which remains on the polyimide support during the interfacial polymerization of polyamide carried out to produce a thin film nanocomposite membrane for organic solvent nanofiltration (OSN). This method is simple, shorter and is environmentally friendly, since no excess MOF is lost during the interfacial polymerization, exhibiting good OSN results: dye rejection of 90% together with a high methanol permeance of 8.7 L m−2 h−1 bar−1.
