“…In order to achieve excellent permeability, many researchers have successively modified the polyamide active layer by adding nanoparticles such as zeolite [ 19 ], carbon nanotubes (CNTs) [ 20 ], silica [ 21 ], molybdenum disulfide (MoS 2 ) [ 22 ] and titanium dioxide (TiO 2 ) [ 23 ]. However, the water flux of the existing modified polyamide/polysulfone forward osmosis membranes is about 10–30 Lm −2 h −1 , restricting the water treatment efficiency in emergency rescues [ 24 , 25 , 26 , 27 ].…”

Mine water cannot be directly consumed by trapped people when a mine collapses, so it is difficult for people to carry out emergency rescues to ensure their safety. Therefore, a water bag made of a forward osmosis (FO) membrane has been designed that can efficiently filter coal mine water to meet the urgent needs of emergency rescue. Before interfacial polymerization (IP), sodium-dodecyl-sulfate-modified halloysite (SDS−HNT) was added to an MPD aqueous solution to prepare an SDS−HNT polyamide active layer, and then the prepared membrane was placed into a polydopamine (PDA) solution formed by the self-polymerization of dopamine and a PDA/SDS−HNT composite film was prepared. The results showed that the original ridge−valley structure of the polyamide membrane was transformed to a rod-, circular-, and blade-like structure by the addition of SDS−HNTs. Subsequently, a dense PDA nanoparticle layer was formed on the modified membrane. The polyamide/polysulfone forward osmosis membrane modified by co-doping of PDA and SDS−HNTs displayed both the best water flux and rejection rate, confirming the synergistic effect of compound modification. Therefore, the high-performance permeability of the polyamide membrane modified by SDS−HNTs and PDA provides great convenience for the emergency filtration of coal mine water, and also has potential applications in wastewater treatment and seawater desalination.

The study investigated the fouling propensity of polysulfone (PSF) hollow fiber (HF) mixed matrix membranes modified with 1.0 wt.% graphene oxide (GO). Using scanning electron microscopy (SEM), atomic force microscopy (AFM), water contact angle (WCA), and mechanical assessments, the structural characteristics of both untreated and GO‐modified PSF HF membranes were examined. Filtration experiments included pure water and model contaminants such as bovine serum albumin (BSA), humic acid (HA), E. coli, and oil‐in‐water emulsion. The GO‐modified membranes demonstrated a significant enhancement in antifouling performance, recovering over 90% of their initial pure water flux with HA and oil, indicating high resistance to irreversible fouling. Additionally, the GO‐modified membranes showed superior oil separation efficiency. However, fouling parameters for BSA were similar for both membrane types, suggesting that GO does not significantly affect membrane‐BSA interactions. Both types of membranes displayed high retention capabilities for E. coli, with no noticeable improvement due to GO addition. This study highlights the potential of GO‐modified PSF HF membranes in enhancing antifouling performance and oil separation efficiency.
