Special Issue Information

Dear Colleagues,

Thin-film composite (TFC) membranes have gained significant attention in recent years due to their exceptional separation performance and versatility in addressing complex separation challenges. The Special Issue on "Advances in Thin-Film Composite (TFC) Membranes" aims to provide a comprehensive platform for researchers and scientists to present and discuss the latest advancements in the field of TFC membranes for various separation applications. The scope of this Special Issue encompasses a wide range of topics related to TFC membranes, including but not limited to, novel material developments, methodologies, and breakthroughs in the design, fabrication, characterization, performance evaluation, mechanism of performance enhancement, and application of TFC membranes. We aim to provide a platform for the dissemination of cutting-edge research findings, novel concepts, and practical solutions that can address existing challenges and pave the way for future advancements in this rapidly evolving field. We accept high-quality research papers as well as review articles. Given your insightful works in the field, we invite you and your colleagues to submit a contribution to this Special Issue, in which some leading experts will describe their works, ideas, and most recent findings.

Abstract
Polyethersulfone (PES) is a polymer popularly used to produce ultrafiltration (UF) membranes. PES is relatively hydrophobic; thus, hydrophilic ingredients are added to the membrane matrix to reduce the fouling intensity. Ingredients such as polyvinylpyrrolidone (PVP) reduce the resistance of PES to NaOH solutions. [...] Read more.
Polyethersulfone (PES) is a polymer popularly used to produce ultrafiltration (UF) membranes. PES is relatively hydrophobic; thus, hydrophilic ingredients are added to the membrane matrix to reduce the fouling intensity. Ingredients such as polyvinylpyrrolidone (PVP) reduce the resistance of PES to NaOH solutions. This study investigated the possibility of using PES membranes for the separation of alkaline cleaning solutions. For this purpose, self-made PES membranes and commercial ultrafiltration PES membranes (UE10—10 kDa and UE50—100 kDa) containing PVP additive were used. The membranes were soaked for 18 months in alkaline (pH = 11.3–11.5) solutions of car washing fluids. It has been found that long-term contact with these solutions caused changes in the structure of the surface layer, especially of membranes containing PVP. As a result, the separation of dextran (100–200 kDa) decreased by 30–40% for PES membranes, 30–40% for UE10 and 40–60% for UE50. Despite these changes, the separation efficiency (rejection of COD, NTU and anionic surfactants) of synthetic car wash wastewater (mixture of surfactants and hydrowax) was similar to the results obtained for pristine membranes.
