Fabrication and Performance Evaluation of Polycarbonate and ChitosanNanocomposite Membranes in Water Purification

Water is vital in advancing human civilization across various sectors, including the economy,agriculture, society, health, education, and international relations. Among traditional purificationmethods, Polymer Nanocomposite membrane technology is particularly effective in removingcontaminants. In this study, Thin film nanocomposite membranes (TFN) were fabricated usingChitosan nanoparticles. To create TFN membranes, the dip coating method was used, applyingpolyvinyl alcohol (PVA)/Chitosan solution on polycarbonate (PC) supporting membranes.Verification of the PVA/Chitosan top active layer on the PC support membrane was conducted usingattenuated total reflectance-Fourier transform infrared (ATR-FTIR) equipment. According to theAtomic force microscopy (AFM) images, it was found that the Ra, Rq, and Rz values decreased asthe content of Chitosan nanoparticles increased up to ۱ wt.%.
