The filler dispersion structure inside MMMs is required to explore in depth to upgrade the PV performance. In this study, an ethoxysilyl functionalized ionic liquid (IL-PTES) modified ZIF-8 nanoparticles (IL-PTES@ZIF-8) were synthesized by one-pot method, and then incorporated into the PDMS matrix to prepare MMMs for PV separation of ethyl acetate (EtOAc) from its diluted aqueous solution. The preferential adsorption performances to EtOAc by IL-PTES, especially for the functions of specific chemical groups in IL-PTES, were researched via molecular dynamicssimulation approach. Furthermore, the IL-PTES covered on ZIF-8 surface could crosslink with PDMS chains, thereby enhancing the interfacial compatibility between ZIF-8 and PDMS. Importantly, the self-aggregated IL-PTES subtly “glued” the nanoparticles together to lead IL-PTES@ZIF-8 a relatively continuous and defect-free distribution state. This condition would lead to a high-efficiency molecular pathway with less polymer phase and much relatively continuous ZIF-8 phase with high selectivity. PV results suggested that the MMMs with 15% IL-PTES@ZIF-8 loading displayed an optimal separation performance with an ultra-high separation factor of 492 (158.7% more than that of pristine PDMS membrane) and normalized EtOAc flux of 4.98 kg μm m<sup>−2</sup>·h<sup>−1</sup> (2 times as much as that of pristine PDMS membrane) for separating 1 wt% EtOAc aqueous solution at 30 °C.

Especially during decolorization of sugarcane juice by nanofiltration (NF), fouling mechanism is still obscure and the fouling formation is difficult to control effectively. Herein, based on the analysis of the real fouling layer residue, seven components are served as model solutes and foulants to study their NF separation performance and fouling behavior. We found that the coexistence of polysaccharides and proteins had no synergistic enhancement on membrane fouling, yet attenuated fouling layer because the formation of large complex produced more shear-enhanced back diffusion. Chlorogenic acid (CA), as a phenolic pigment and main pore foulant, aggravates the polysaccharides or proteins fouling owing to its bridging effect between membrane and large foulants, especially polysaccharides with high hydrophilicity. Laccase can catalyze oxidation and self-polymerization of CA, not only reducing its accessibility to block the pores and the bridging effect, but also in-situ forming a hydrophilic coating layer on the membrane surface, which is regarded as an effective pretreatment strategy for fouling control. During the cross-flow filtration of real sugarcane juice, the average permeate flux increases by 67.1% and irreversible fouling decreases by 21.2%, showing great application potential due to its biocompatibility and considerable economic benefits. This work not only elaborately elucidates the fouling mechanism among components in cane juice decolorization by NF, but also proposes an innovative approach to reconstitute fouling layer for improving membrane antifouling performance in practical application.</p></div>","PeriodicalId":100033,"journal":{"name":"Advanced Membranes","volume":"1 ","pages":"Article 100010"},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2772823421000117/pdfft?md5=c1d58b02c69ef34ec24ae4350caf936a&pid=1-s2.0-S2772823421000117-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91499474","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Given the importance of PES membranes for hemodialysis, various modification methods have been developed to address this challenge; and it is necessary to review the research progress in hemocompatibility enhancement of PES membranes, which is also imperative to provide more insights for the development of future PES-based hemodialyzers and perhaps to open the door to extend their applications for the next generation of blood purification instruments, like the wearable artificial kidney. Herein, we review the concept and principles of hemocompatibility for hemodialysis membranes, different strategies developed to improve the hemocompatibility of PES membranes, and the challenges and future perspectives for improvement in hemocompatibility of PES membranes.
