• pollution in cellulose triacetate (CTA) membranes during seawater desalination, silver (Ag) nanoparticles were incorporated onto the CTA surface using polydopamine (PDA). PDA, which contains phenolic and amino groups, exhibits excellent adhesiveness and provides active sites for the attachment and reduction

• rates of the Ag@PCTA membrane were comparable to those of the parent CTA membrane. Keywords: antibacterial properties; cellulose triacetate; nanosilver; seawater desalination; Introduction As the global population continues to grow at a rapid pace, the demand for freshwater resources is escalating

• oxygen species (ROS) that damage bacterial cell membranes and DNA [19]. The incorporation of these nanomaterials into seawater desalination membranes not only significantly improves salt rejection and water flux but also markedly enhances antibacterial properties, thereby extending the operational

• membranes with hydrophobic photothermal material particles. Over the past years, various types of SSG membranes have been studied [37][39][45][54][56][57]. These SSG membranes can be applied to, for example, seawater desalination and photocatalytic degradation by utilizing the photothermal and separation

• materials, because low cost, reusability, chemical stability, and mass production will be required in the future. Furthermore, by designing the evaporator, it can be applied to various fields, such as seawater desalination, sterilization, and power generation. There is still room for research on how to
