Unraveling the film‐formation kinetics of interfacial polymerization via low coherence interferometry

Interfacial polymerization (IP) is one of the most important methods for fabricating thin film composite (TFC) membranes. Understanding the film‐formation mechanisms is of great value for developing membranes with enhanced performance. This work proposed a novel method to in situ characterize the film‐formation kinetics via low coherence interferometry (LCI). The polyamide film formed at the liquid–substrate interface was scanned in real time;...
