Polyelectrolytes as Building Blocks for Next-Generation Membranes with Advanced Functionalities

ACS Applied Polymer Materials, Journal Year: 2021, Volume and Issue: 3(9), P. 4347 - 4374

Published: Aug. 26, 2021

The global society is in a transition, where dealing with climate change and water scarcity are important challenges. More efficient separations of chemical species essential to reduce energy consumption provide more reliable access clean water. Here, membranes advanced functionalities that go beyond standard separation properties can play key role. This includes relevant functionalities, such as stimuli-responsiveness, fouling control, stability, specific selectivity, sustainability, antimicrobial activity. Polyelectrolytes their complexes an especially promising system membrane functionalities. we have reviewed recent work stem directly from the material provided by polyelectrolytes. highlights versatility polyelectrolyte-based modifications, polyelectrolytes not only applied single layers, including brushes, but also complex polyelectrolyte multilayers on both porous supports dense membranes. Moreover, free-standing be produced completely aqueous solutions allowing much sustainable approaches fabrication. Review demonstrates promise hold for next-generation properties, while it provides clear outlook future this field.

Hollow fiber nanofiltration: From lab-scale research to full-scale applications

Journal of Membrane Science, Journal Year: 2022, Volume and Issue: 669, P. 121234 - 121234

Published: Dec. 10, 2022

This review provides a comprehensive overview on the quickly developing field of polymeric hollow fiber (HF) nanofiltration (NF), including membrane (module) and process design, operational parameters, full-scale applications. Six different methods are currently used to produce HF NF membranes: phase inversion, interfacial polymerization, grafting, coating, polyelectrolyte multilayers (PEM) chemistry in spinneret. While all have their strengths weaknesses, several PEM based membranes stand out because high chemical stability. combination geometry stability can make sustainable alternative spiral wound NF. is especially case for applications with fouling load where, contrast NF, typically does not require an intensive pre-treatment. In academic settings, experiments done small modules single-component feeds. Several studies showed that it important, but always straightforward, correlate these lab scale results full performance. Indeed, design parameters such as crossflow velocity staging partly determine energy consumption retention need be taken into account. Partly insights developments, last five years commercial rapidly become available. At least 59 pilot-scale 26 plants operation or under construction, mostly focusing water treatment. A comparison between shows applied broad range excellent scalability, highlighting growth potential coming years.

Published: Sept. 9, 2022

Polyelectrolyte multilayer (PEM) films and particularly hollow capsules composed of PEM shells have gained significant interest since their introduction. Their compositional versatility easiness preparation via so-called layer-by-layer assembly led to the development numerous systems containing also stimuli-responsive components. This paper reviews achievements related formation, determination structure, properties responding major physical, chemical, biological stimuli. applications as e.g., microcarriers for controlled delivery release active components, substrates cells' growth, coatings enhanced surface adhesion, or self-healing anticorrosive are shown discussed. The influence various stimuli on integrity, permeability shell presented together with in biomedicine drug well biotechnology industrial protective coatings.
