Description
Summary:[Display omitted] •The electrified liquid–liquid interface is modified with nylon-6,6.•Electrochemically-controlled transfer of diamine triggers the polyamide formation.•Microcapillaries are used as the support of the ITIES and polyamide films.•The polyamide films show size-sieving properties. The interfacial polymerization of nylon-6,6 is studied at the polarized liquid–liquid interface. The optimal conditions (concentration of reagents in a biphasic system, pH of the water phase, voltammetric cycling) are used to modify the interface, supported by a microcapillary, giving a platform with molecular sieving properties.
