The enhancement of antibacterial and anti-biofouling properties of chitosan/silver nanoparticles-grafted composite polyamide membrane

This study endeavors to augment the antibacterial and anti-biofouling properties of thin-film composite polyamide membranes by subjecting them to modification with antibacterial chitosan and silver nanoparticle materials through the UV-induced graft polymerization technique. Various surface assessment methods were employed, and the efficiency of the membrane performance was demonstrated through the flux and the retention of the filtration process, which used calcium chloride as the foulant. Antibacterial, antifouling, and anti-biofouling capabilities were assessed through several tests. The findings revealed that the chitosan/silver nanoparticles-grafted membranes exhibited superior antibacterial and anti-biofouling abilities with consistent flux and enhanced retention, underscoring the prospective implementation of this approach in filtration systems to curtail biofouling and bolster overall efficacy.
