Monitoring the Interfacial Polymerization of Piperazine and Trimesoyl Chloride with Hydrophilic Interlayer or Macromolecular Additive by In Situ FT-IR Spectroscopy
The interfacial polymerization (IP) of piperazine (PIP) and trimesoyl chloride (TMC) has been extensively utilized to synthesize nanofiltration (NF) membranes.However, it is still a huge challenge to monitor the IP reaction, because of the fast reaction rate and the formed ultra-thin film.Herein, two effective strategies were applied to reduce the
