Tailoring Morphology and Properties of Tight Utrafiltration Membranes by Two-Dimensional Molybdenum Disulfide for Performance Improvement.

To enhance the permeation and separation performance of the polyethersulfone (PES) tight ultrafiltration (TUF) membrane, two-dimensional molybdenum disulfide (MoS2) was applied as a modifier in low concentrations. The influence of different concentrations of MoS2 (0, 0.25, 0.

Polydopamine-Assisted Two-Dimensional Molybdenum Disulfide (MoS)-Modified PES Tight Ultrafiltration Mixed-Matrix Membranes: Enhanced Dye Separation Performance.

Tight ultrafiltration (TUF) membranes with high performance have attracted more and more attention in the separation of organic molecules. To improve membrane performance, some methods such as interface polymerization have been applied. However, these approaches have complex operation procedures.

Impacts of Sulfuric Acid on the Stability and Separation Performance of Polymeric PVDF-Based Membranes at Mild and High Concentrations: An Experimental Study.

This study investigated the effects of an aqueous acidic solution at typical concentrations on polymeric polyvinylidene fluoride (PVDF)-based membranes. Flat-sheet PVDF-based membranes were completely embedded in sulfuric acid at varying concentrations. The effect of the acid concentration after a prolonged exposure time on the chemical, mechanical and physical properties of the membrane were checked via FE-SEM, EDX (Energy-Dispersive Spectrometer), FTIR, XRD, tensile strength, zeta potential, contact angle, porosity, pure water flux measurement and visual observation.

Scalable TiCT MXene Interlayered Forward Osmosis Membranes for Enhanced Water Purification and Organic Solvent Recovery.

The design of nanosheets interlayer between the substrate and polyamide layer has attracted growing attention to improve the performance of thin-film composite membranes. However, the membrane size is limited by current fabrication methods such as vacuum filtration. Herein, a high-performance MXene (TiCT) interlayered polyamide forward osmosis (FO) membrane is fabricated based on a combination of a facile and scalable brush-coating of MXene on nylon substrates and the interfacial polymerization process.
