Abstract Hydrophilically-modified mesh filter membranes have been widely researched for oil/water separation due to their high permeating flux and excellent separation efficiency. However, the low oil pressure resistance of mesh membrane is a major drawback limiting its practical oil/water separation applications. In this work, we report an ultrathin microporous membrane developed via the decoration of a stainless steel mesh filter with electrospun poly(acrylic acid) grafted poly(vinylidene fluo...

Abstract Ionic liquids (ILs) show a wide range of applications as “green” solvents in the new era and the recovery of water-soluble ILs has become an urgent issue. Herein, for the first time, osmotic distillation is applied to concentrate and recover water-soluble ILs by a series of hydrophobic membranes. Poly(vinylidene fluoride) membrane with vertically oriented pores and stainless steel mesh were hydrophobically modified and then compared with commercial membranes to demonstrate the influence...

Abstract A novel hydrophilic/hydrophobic bi-comb-shaped amphoteric membrane was for the first time designed by the one-pot reactions of PBI with bromohexane and 1,3-propanesultone. The sulfonic acid chain promotes the formation of amphoteric ion clusters, while the alkyl side chain enhances the packing of hydrophobic segments. This unique structure design optimizes the segregated microphase morphology of the membrane, which is proved by TEM. Compared to the membrane without alkyl side chain, the...

Abstract Novel nanofiltration (NF) membranes with improved flux, dye rejection, high pH and temperature resistance were developed using a disulfonated diamine co-monomer, disodium-3-3′-disulfone-4-4′-dichlorodiphenylsulfone (S-DADPS). Thin film composite (TFC) NF membranes were fabricated on a porous polysulfone-based ultrafiltration support layer via the interfacial polymerization between trimesoyl chloride (TMC) in the organic phase and S-DADPS/piperazine (PIP) mixture in the aqueous phase. Th...

Abstract Herein, we designed the solid polymer electrolytes (SPEs) via the polymerization of poly(ethylene glycol) diacrylate (PEGDA) with different molecular weights under a UV irradiation in the presence of 2-formyl benzene boric acid (PBA)- terminated poly(propylene glycol)-b-poly(ethylene glycol)-b-poly(propylene glycol) (NH2-ED2000-NH2) (diPBA-ED2000). The SPEs with the boroxine structure were obtained by the dehydration and condensation of the diPBA-ED2000. The ionic conductivity and mecha...

Abstract A thin-film polyamide layer was synthesized on three different hollow-fiber support layers, each of which possess different morphological structures (i.e., sponge-like structures (SM 1), finger-like macrovoid close to the outer surface (SM 2), and middle-partitioned finger-like structures (SM 3)). In this work, we found that forward osmosis (FO) performance of thin-film composite (TFC) membranes could be significantly affected by their sub-layer morphology. During FO tests, SM-1 showed ...

Abstract Zwitterions have been attracting great attention for researchers to tailor the separation membranes featuring enhanced water permeability and excellent antifouling property. Here we functionalized polyamide membrane surface with small-molecule zwitterions through sequential interfacial polymerization (SIP) technique to improve the performance of RO membranes. Zwitterionic molecules 3-(4-(2-((4-aminophenyl)amino)ethyl)morpholino-4-ium)propane-1-sulfonate (PPD-MEPS) and amino acid arginin...

Abstract Herein, as a binder (or catalyst ionomer) for AEMFCs, we investigated the effect of two different cationic copolymers based on poly(phenylene oxide) (PPO) with N-cyclic quaternary ammonium (QA) groups, including six-membered dimethyl piperidinium (DMP) and bis-six-membered azonia-spiro undecane (ASU). An earlier report on the same polymers for membranes in AEMFCs indicated the better electrochemical performance of PPO-ASU compared with PPO-DMP. Therefore, we would like to investigate th...

Abstract Membrane technology is believed as a cost-effective approach for solving the water issues, whereas it suffers from serious membrane fouling. Surface grafting and surface coating have been proved to be effective in abating the membrane fouling; however, these processes always need additional procedures and compromise the initial permeance of the membranes. Herein, we developed a kind of highly permeable polyacrylonitrile (PAN) membranes with excellent anti-fouling performance through one...

Abstract Further improvement of nanofiltration is significantly hindered by the trade-off between the permeability and selectivity. This study proposes a new strategy of significantly improving performance by enhancing the effective membrane area, hydrophilicity, membrane porosity, negative charges of a membrane, and decreasing pore size through designing a new polyarylene thioether sulfone/sulfonated sulfone (PATS/SS) copolymer. Via copolymerization, thioether (-S-) and sulfonic groups were int...
