Exploring the structure-properties relationships of novel polyamide thin film composite membranes

Polysulfone (PSU) is a material widely used in the fabrication of membranes for ultrafiltration and as a support for nanofiltration and reverse osmosis membranes. Interfacial polymerization usually combines amine and acid chloride monomers for the fabrication of thin film composite membranes[1] . However, only few publications describe it’s usage for the modification of supports for the fabrication of ultrafiltration membranes [2].

This research focuses on the modification of PSU supports to produce new ultrafiltration membranes. The advantages of interfacial polymerization in the fabrication of UF membranes includes: Negatively charged PSF surfaces that could be less prone to biofouling Scale up process for the modification of PSU.

An alternative to costly and technically challenging processes as in situ interfacial polymerization [3].
