Fabrication and Characterization of PAA‑<i>g</i>‑PES Polymers and Resultant Membranes: Combating Fouling through the Introduction of Hydrophilic PAA Brushes.

ABSTRACT: The adoption of polymeric membranes for reclamation of natural organic pollutant-impacted water has been of recent interest. However, membrane fouling has been an obstacle in the application of membranes over a longer period. Fouling, which is mainly caused by organic materials, is a universal challenge in membrane technology for water treatment. The hydrophobic nature of poly-(ether sulfone) (PES) membranes has a high affinity toward organic compounds. To elevate this challenge, in this study, hydrophilic brushes of poly-(acrylic acid) (PAA) were grafted onto the PES backbone using free radical graft polymerization. The successful grafting of PAA brushes on PES was confirmed through characterization using Fourier transform infrared spectrophotometry, ¹H NMR, ¹³C NMR,
