Sharpening Nanofiltration: Strategies for Enhanced Membrane Selectivity

ACS Applied Materials & Interfaces, Journal Year: 2020, Volume and Issue: 12(36), P. 39948 - 39966

Published: Aug. 12, 2020

Nanofiltration plays an increasingly large role in many industrial applications, such as water treatment (e.g., desalination, softening, and fluoride removal) resource recovery alkaline earth metals). Energy consumption benefits of nanofiltration processes are directly determined by the selectivity membranes, which is largely governed pore-size distribution Donnan effects. During operation, separation performance unmodified membranes will also be impacted (deleteriously) upon unavoidable membrane fouling. Many efforts, therefore, have been directed toward enhancing can classified into fabrication method improvement process intensification. This review summarizes recent developments field provides guidance for potential future approaches to improve membranes.

Transparent Polymer‐Ceramic Hybrid Antifouling Coating with Superior Mechanical Properties

Advanced Functional Materials, Journal Year: 2021, Volume and Issue: 31(19)

Published: Feb. 28, 2021

Abstract Antifouling coatings are often required to have both excellent fouling resistance and mechanical properties for their applications. This study reports a water‐borne antifouling coating consisting of an amine‐terminated hyperbranched polysiloxane resistant epoxy‐zirconium particle, where the former is prepared using amine‐functionalized silanes, latter via reaction zirconium alkoxide with epoxy‐functionalized silanes zwitterionic silanes. Such hybrid transparent (>99.5% transmittance) exhibits combination polymeric ceramic characteristics, namely, it has not only high hardness (7–9 H) adhesion (≈3 MPa) substrates but also good flexibility (≤10 mm bending diameter). The presence group allows oil repellency resistance. effects composition structure on performance investigated. aims develop be used in foldable displays, optical sensors, biomedical facilities.

One of the most detrimental consequences surface colonization by bacteria is healthcare-associated infections (HAIs), which contribute to increased patient mortality and morbidity. Medical devices inserted into body provide a route for bacterial migration conducive surfaces their attachment proliferation. Antibacterial coatings can potentially minimize consequently reduce occurrence HAIs. function either inhibiting (antifouling coatings) or killing attached and/or in vicinity (bactericidal coatings). On an antifouling coating, any bacterium that manages attach will proliferate, while on bactericidal coatings, accumulation dead debris provides opportunities other colonize surface. As such, integration functionalities single coating combines advantages each, increasing probability be successfully inhibited.
