摘要 ：
Graphene oxide (GO) membrane has been considered as a promising approach for harvesting pure water from various wastewater to deal with the current water shortage issue, arising from its distinctive 2D channel features. However, the narrow interlayer distance (0.75 angstrom) of GO nanosheets hampers the utilization of GO membranes for dye wastewater treatment, which demands superior water permeance, high dyes rejection, and low salts rejection. Herein, an in-situ anchored nanoparticle strategy is designed to fabricate Fe(OH)(3)@GO membrane to enlarge the interlayer distance via the uniform distributed Fe(OH)(3) nanoparticles. Benefiting from the in-situ transformation of Fe3+ into positively charged Fe(OH)(3) nanoparticles, the interlayer distance of GO membranes can be tailored via changing the Fe: GO mass ratio and hydrolysis time. The optimized Fe(OH)(3)@GO membrane realizes a superior water permeance of similar to 90.9 LMH/bar (similar to 19-fold enhancement compared with GO membranes), with >99% and <4% rejection to Evans blue (EB) and NaCl, respectively. Thus, the membrane can be applied for dye desalination and can be stably running for 85 h. Considering the facile and efficient 2D channel tunability, our strategy provides an innovative approach for construction of high-performance 2D membranes.

摘要 ：
Alcohol-permselective pervaporation is a breakthrough technology in industrial separation applications. A highflux pervaporation membrane is demanded in cost saving. In this study, an ultrathin metal-organic framework (MOF) membrane was formed on a porous polymer substrate using a hydroxyl salt induced in situ growth method. Then, the obtained MOF membrane was modified through a sulfidation strategy to enhance the transport of alcohol molecules. The aperture of the MOFs was enlarged to form a hollow structure. Subsequently, polydimethylsiloxane was spin-coated on the MOF membrane to eliminate the grain boundary defects and improve the hydrophobicity, without increasing the thickness of the MOF layer. Based on the ultra-fast transport channels, the modified MOF membrane exhibited an ultrahigh flux of 11.6 kg m(- 2) h(-1) with comparable separation factors for 5 wt% ethanol aqueous solution at 60 degree celsius. The diffusion mechanism of alcohol molecules was confirmed by the molecular dynamic simulation.

摘要 ：
Blending hydrophilic additives is an effective method to improve the surface hydrophilcility and antifouling property of ultrafiltration membranes. In this study, we prepared a series of polysulfate (PSE) hollow fiber membranes (HFMs) containing a zwitterion-based copolymer, poly(4-vinylpyridine-co-methylacryloxyethyl phosphocholine), with varying monomer ratios and blending quantities. The relationship between cast solution properties and phase separation behavior was investigated, as well as the impacts of copolymer composition and amount on the separation performances and antifouling abilities of the membranes. A higher hydrophilic monomer ratio and more copolymer addition of zwitterionic copolymer would facilitate surface segregation, increasing the hydrophilicity of membrane surface and generating a dense hydration layer. This layer can resist macromolecule contaminants and promote water molecular transport. Furthermore, a more compacted skin layer improves separation ability. The optimized PSE HFMs had water fluxes around 140 L m- 2 h- 1, BSA rejections over 97 %, and flux recovery rates over 92 % during operation. Moreover, the membrane demonstrated ultra-low flux-sacrifice when applied to protein solutions while maintaining a high rejection rate, which indicates the distinctive and strong competitiveness of PSE/P(4VP-co-MPC) HFMs.

摘要 ：
Recycling of valuable solutes and recovery of organic solvents via organic solvent nanofiltration (OSN) are important for sustainable development. However, the trade-off between solvent permeability and solute rejection hampers the application of OSN membranes. To address this issue, the poly(3,4-ethylenedioxythiophene):poly(styrene sulfonate) (PEDOT:PSS) nanoparticle membrane with hierarchical pores is constructed for OSN via vacuum filtration. The small pores (the free volume of the polymer chain) charge for the solute rejection (high rejection efficiency for low molecule weight solute) and allow solvent passing while the large pores (the void between two PEDOT:PSS nanoparticles) promote the solvent transport. Owing to the lack of connectivity among the large pores, the fabricated PEDOT:PSS nanoparticle membrane enhanced solvent permeance while maintaining a high solute rejection efficiency. The optimized PEDOT:PSS membrane affords a MeOH permeance of 7.2 L m(-2) h(-1) bar(-1) with over 90% rejection of organic dyes, food additives, and photocatalysts. Moreover, the rigidity of PEDOT endows the membrane with distinctive stability under high-pressure conditions. The membrane is used to recycle the valuable catalysts in a methanol solution for 150 h, maintaining good separation performance. Considering its high separation performance and stability, the proposed PEDOT:PSS membrane has great potential for industrial applications.

摘要 ：
Graphene oxide (GO) is regarded as a promising next-generation high-performance separation membrane material. However, the flexiblility of single-layer GO nanosheets usually results in membrane with poor stability under practical conditions. In this study, we present a facile strategy to rapidly convert single-layer nanosheet GO membranes into supra-nanosheet GO (sGO) membranes with a loose rigid structure by a confined gelling and crosslinking process. The optimized sGO membrane exhibits remarkable water permeance and retention capability. With additional tailor-made nanopores, the water permeance of the sGO membrane could reach 52.0 LMH/bar, representing 10-fold increase compared to pristine GO membrane. Furtheermore, this membrane demonstrates excellent pressure stability and unique elasticity, enhancing its lorg-term operational reliability and reversible recovery. Hence, this innovative strategy provides a platform for the facily construction of highly stable 2D membranes with enhanced water transport channels.

摘要 ：
Mixed matrix membranes exhibit enhanced selectivity and permeability, but stability still needs to be improved. In this study, we prepared ZIF-8/PEBA mixed matrix membranes with different loadings and used interface induction to control the directional distribution of nanoparticles. The controlled directional distribution of ZIF-8 in PEBA was studied by optical microscopy and scanning electron microscopy. The effects of different ZIF-8 loading amounts on the formation and pervaporation performance of mixed matrix membranes were thoroughly studied. The prepared membrane was applied to 1 wt% n-butanol aqueous solution, achieving a high flux of 4.9 kg m- 2 h-1 and a separation factor of 18.8. The directional distribution of nanoparticles in PEBA prevents direct contact with the feed liquid and effectively protects the structural stability of ZIF-8. The resulting ZIF-8/ PEBA membrane showed excellent stability after more than 100 h of operation.

摘要 ：
The increase demand on clean water accompanied with water shortage is now threatening the ecosystem and human life, which is aggravated with the rising of heavy-metal-ion polluted water. Thus, water purification from metal-ion contained wastewater is of significance. The metal ions removal could achieve two aims simultaneously: harvesting clean water and recovering the valuable metal resource. Nanofiltration (NF) membranes, featured with the nanopore size and energy-efficiency, demonstrate great promise for separation of metal ions from wastewater, which has not been fully exploited with the rapid growth of advanced materials. Thus, a summarization on the recent progress in this field is essential. In this review, we will start with the introduction of separation mechanism. Then, the possible materials used for NF membrane construction will be given. Subsequently, the commonly used NF fabrication techniques will be detailed with some examples. Next, the NF applications in treatment of various heavy metal ions polluted water will be thoroughly discussed. Finally, the perspectives future directions will be provided. This review is expected to shine a light on the fabrication of NF membranes for high-performance removal of heavy metal ions from the wastewater, realizing the water purification and metal recovery.

摘要 ：
Organic molecule desalination with nanofiltration has important practical application significance. Zwitterionbased nanofiltration membranes (ZNFMs) with selective channels for monovalent salts have been prepared to improve the separation performance. However, most ZNFMs tend to be restricted by their loose structures, which results in unsatisfactory rejection for small molecules with sub-200 Da molecular weight. In this study, a synchronous modification strategy during the heat treatment of interfacial polymerization was proposed, in which various multi-amine solutions were employed as the novel medium of heat treatment to regulate the structures of ZNFMs. The pore size distribution of membranes could be narrowed to a certain degree through cross-linking by corresponding multi-amines. The optimized ZNFMs exhibited excellent retention to small molecules. For example, the retention of glucose was dramatically increased to 96.5%. Meanwhile, the ZNFMs also had low rejection for monovalent salts, such as KCl (26.7 %). Consequently, the separation factor between glucose and KCl reached 21.2, which demonstrated a great potential for organic molecule desalination with sub-200 Da molecular weight.

摘要 ：
Incorporating zwitterionic materials into polymer matrix is an effective method to fabricate high-performance ultrafiltration membranes, which can improve the surface hydrophilicity while optimizing the internal structure of the membrane. In this study, a series of zwitterionic copolymers, 4VP-MPC, were synthesized using 4vinylpyridine (4VP) and 2-methylacryloxyethyl phosphocholine (MPC), and their impact on the phase inversion process of polysulfate (PSE) was investigated thoroughly by changing the addition amount and altering the copolymer composition. The addition of 4VP-MPC accelerated the phase inversion rate, reduced the skin layer thickness and improved the membrane porosity. Moreover, the hydrophilicity of the membrane surface is enhanced due to the segregation of the zwitterionic copolymer during the membrane formation process. A novel PSE/4VP-MPC membrane with good separation performance and antifouling property was fabricated, with a pure water flux of 221 L/(m2 h bar), a BSA rejection rate of 93.3 %, and a flux recovery rate of 94.6 %. Additionally, when filtering the mixed simulated dialysate, the optimized membrane showed clearance rates of 71.3 % and 97.0 % for lysozyme and urea respectively, while maintaining a high BSA rejection. This PSE/4VP-MPC blend membrane demonstrated potential applications in the field of ultrafiltration, including hemodialysis.
