Nanofibrous Porous Organic Polymers and Their Derivatives: From Synthesis to Applications

Advanced Science, Год журнала: 2024, Номер 11(19)

Опубликована: Март 12, 2024

Abstract Engineering porous organic polymers (POPs) into 1D morphology holds significant promise for diverse applications due to their exceptional processability and increased surface contact enhanced interactions with guest molecules. This article reviews the latest developments in nanofibrous POPs derivatives, encompassing polymer nanofibers, composites, POPs‐derived carbon nanofibers. The review delves design fabrication strategies, elucidates formation mechanisms, explores functional attributes, highlights promising applications. first section systematically outlines two primary approaches of POPs, i.e., direct bulk synthesis electrospinning technology. Both routes are discussed compared terms template utilization post‐treatments. Next, performance derivatives reviewed including water treatment, water/oil separation, gas adsorption, energy storage, heterogeneous catalysis, microwave absorption, biomedical systems. Finally, highlighting existent challenges offering future prospects concluded.

The Potential of Electrospun Membranes in the Treatment of Textile Wastewater: A Review

Polymers, Год журнала: 2024, Номер 16(6), С. 801 - 801

Опубликована: Март 13, 2024

Water security and industrial wastewater treatment are significant global concerns. One of the main issues with environmental contamination has been discharge dye from textile industries, contributing to an ever-growing problem water pollution, poisoning supplies, harming ecosystem. The traditional approach found be inefficient, biosorption techniques mechanisms have proven a successful replacement for conventional methods. Recent developments led recognition fibrous materials as environmentally friendly option broad application in several including treatment. This review explores potential produced by electrospinning technique adsorbents treatment, while at same time, removal adsorbates such oil, dyes, heavy metals, other substances, reported literature. Textile filtering structures, electrospinning, summarized use synthetic natural polymers this purpose is discussed. limitations electrospun structures also mentioned. Electrospun nanofibrous membranes appear very promising route filter therefore contribute reuse reducing courses.

Kosmotropes and chaotropes: Specific ion effects to tailor layer-by-layer membrane characteristics and performances

Journal of Membrane Science, Год журнала: 2023, Номер 672, С. 121446 - 121446

Опубликована: Фев. 1, 2023

So-called specific ion effects strongly impact physicochemical phenomena in among others, morphologies of polymeric membranes. This can be correlated to the identity ions, rather than just their charge or concentration. We use this effect tune properties layer-by-layer membranes prepared with polyelectrolytes polydiallyldimethylammonium chloride and polystyrene sodium sulfonate. To systematically study this, were using different salts (NaBr, NH4Cl, MgCl2, NaCl, LiCl, MgSO4, NaH2PO4, (NH4)2SO4, Na2SO4). The evaluated thanks classification PEs into kosmotropes (well hydrated) chaotropes (poorly following law matching water affinities (LMWA). type anions cations on multilayer formation membrane performances was evaluated. Membranes kosmotropic achieved stable after only 4 bilayers, almost 6 times higher permeabilities chaotropic without compromising often even improving membrane's size exclusion behaviour. used tuned charge: Kosmotropic delivered negatively charged Na2SO4 MgCl2 retentions till 97% 10% respectively, while formed more positively reversed behaviour rejection 20 89%.
