摘要：

The fouling behavior of polyamide thin-film composite (TFC) membranes modified with amino- and diethylamino-cyclodextrins (CDs) through an in situ interfacial polymerization process is reported. Modified polyamide TFC membranes exhibited improved hydrophilicity, water permeability, and fouling resistance as compared to the unmodified TFC membranes, while restricting the passage of NaCl salt (98.46 +/- 0.5%). The increase in hydrophilicity was attributed to the secondary and tertiary hydroxyl groups of the CDs, which were not aminated. The membranes modified with amino-CDs had increased surface roughness while the membranes modified with diethylamino-CDs had smoother surfaces. However, despite the surface roughness of the membranes modified with amino-CDs, low fouling was observed due to the highly hydrophilic surfaces, which superseded the roughness.
