Doctor-blading-assisted interfacial polymerization for green and scalable polyamide membrane fabrication.

ABSTRACT: Industry-leading polyamide membranes are thin-film composites produced via interfacial polymerization (IP) at an alkane-water interface. However, the current fabrication method results in suboptimal membrane microstructure and compromised performance due to insufficient control of mass and heat transfer within the interfacial reaction zone. Furthermore, the fabrication process utilizes volatile alkane solvents, contributing to a significant environmental burden. Here, we report an IP strategy at an ionic liquid/water interface to synchronously achieve kinetic and thermodynamic control of the interfacial reaction, thereby optimizing the microstructure of polyamide membranes. The high viscosity and low volatility of the ionic liquid facilitate the integration of the industrial doctor blading
