“…Extending the applicability of CNTs toward an enhanced flow and fouling resistance, MWCNTs were added to PVDF membranes by an atomic transfer radical addition (ATRA). 68 Adding amine-modified MWCNTs (ethylamine-, octylamine-, and octadecylamine-linkers) increased their dispersibility and hydrophilicity in the innovative PVDF membranes.…”

“…Equally, Park et al [ 45 ] modified a fluoropolymer matrix of PVDF with amine-modified multiwall carbon nanotubes (MWCNTs) mediated by a complexation copper mediated reaction through an atomic transfer radical addition (ATRA) using the hydrophilic Cu[DNDP] 3 MWCNT-EA complex as a non-removable intermediary. They also employed the non-solvent induced phase separation process (NIPS) for the membrane preparation.…”

Copper-Modified Polymeric Membranes for Water Treatment: A Comprehensive Review

et al. 2021

In the last decades, the incorporation of copper in polymeric membranes for water treatment has received greater attention, as an innovative potential solution against biofouling formation on membranes, as well as, by its ability to improve other relevant membrane properties. Copper has attractive characteristics: excellent antimicrobial activity, high natural abundance, low cost and the existence of multiple cost-effective synthesis routes for obtaining copper-based materials with tunable characteristics, which favor their incorporation into polymeric membranes. This study presents a comprehensive analysis of the progress made in the area regarding modified membranes for water treatment when incorporating copper. The notable use of copper materials (metallic and oxide nanoparticles, salts, composites, metal-polymer complexes, coordination polymers) for modifying microfiltration (MF), ultrafiltration (UF), nanofiltration (NF), forward osmosis (FO) and reverse osmosis (RO) membranes have been identified. Antibacterial and anti-fouling effect, hydrophilicity increase, improvements of the water flux, the rejection of compounds capacity and structural membrane parameters and the reduction of concentration polarization phenomena are some outstanding properties that improved. Moreover, the study acknowledges different membrane modification approaches to incorporate copper, such as, the incorporation during the membrane synthesis process (immobilization in polymer and phase inversion) or its surface modification using physical (coating, layer by layer assembly and electrospinning) and chemical (grafting, one-pot chelating, co-deposition and mussel-inspired PDA) surface modification techniques. Thus, the advantages and limitations of these modifications and their methods with insights towards a possible industrial applicability are presented. Furthermore, when copper was incorporated into membrane matrices, the study identified relevant detrimental consequences with potential to be solved, such as formation of defects, pore block, and nanoparticles agglomeration during their fabrication. Among others, the low modification stability, the uncontrolled copper ion releasing or leaching of incorporated copper material are also identified concerns. Thus, this article offers modification strategies that allow an effective copper incorporation on these polymeric membranes and solve these hinders. The article finishes with some claims about scaling up the implementation process, including long-term performance under real conditions, feasibility of production at large scale, and assessment of environmental impact.

Ordered porous membranes have wide and important application prospects in the fields of filtration, separation, catalysis, biomedicine, etc., and have attracted growing interest in the field of material science. Among diverse membrane preparation approaches, breath pattern method has been widely concerned due to its simplicity in the preparation, ease in tuning the structure/property and functionality of formed membranes, and broad utility for various polymers. With the development of material design, the application spectrum of breath figure membrane has been greatly expanded. However, since the pore morphology of porous membrane is influenced by many factors, the controlling mechanism of normalization has not been clear yet. In this paper, the research progress of film-forming materials in recent years is reviewed, and the correlation between pore formation and pore morphology is discussed in details. This information will provide a systematic and in-depth perspective for research in this filed and an important guideline for the preparation of the ordered porous films with divergent applications.
