Typically, most electronic devices run on a lithium-ion battery (LIB). However, safety issues prompt researchers to consider alternatives, and the aqueous zinc-ion battery (AZIB) emerged as an alternative with higher merits. One of the fundamental segments of the AZIB is the separator that provides ion transportation on both sides of the battery while deterring direct contact between the cathode and anode. For AZIBs, glass fiber (GF) is the most conventional separator considering their availability and cost-effectiveness, suffering from various hurdles, for instance, dendrite formation, which is the primary concern, causing an explosion during battery operation, and the low mechanical strength. Conversely, the polyacrylonitrile (PAN) prevents dendrite formation through the electrostatic interaction, deposition along the (002) plane, 3D diffusion, and selective zinc ion permeation, and offers high cyclability. We segment this paper into four parts: first, it discusses the basic features of the ideal separator; second, the preparation methods of the separator; third, a critical overview of the PAN-based separator for AZIB, especially the dendrite mitigation strategies; and finally, it provides the future directions and strategies for advance PAN-based separator design.</p>","PeriodicalId":145,"journal":{"name":"Chemistry - An Asian Journal","volume":" ","pages":"e00810"},"PeriodicalIF":3.3,"publicationDate":"2025-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145063057","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A series of Nafion membranes with cellulose ratios of 5, 10, 20, and 30 wt% were fabricated and labeled CNF5, CNF10, CNF20, and CNF30, respectively. The CNF20 displayed promising thickness (∼77 µm) and mechanical stability, and as a result, it was investigated further and compared with the commercial Nafion 117 membrane. CNF20 exhibited an ion exchange capacity of 1.35 meq/g, water uptake of 39% and ionic conductivity of 0.090 S/cm. Both membranes exhibited a charge capacity of approximately 555.5 mAh/L. However, CNF20 retained 99.9% of its capacity, as compared to 93.7% for Nafion 117, after 100 cycles. The charge capacity decay and discharge capacity decay for CNF20 were 18 times and 120.6 times lower, respectively, than for the Nafion 117 membrane. The CNF20 showed energy efficiency of 31.3% whereas Nafion 117 exhibited 23.2% over 100 cycles. The cost analysis for CNF20 resulted in a 57.7% reduction as compared to the commercial price of Nafion 117.

The dinuclear complexes quench aggregation-induced enhanced emission in the presence of trinitrophenol (TNP/Picric Acid: PA) selectively from a batch of nitroaromatics in water, whereas the mononuclear complex is not selective. Therefore, dinuclear complexes were employed to selectively detect the explosive nitroaromatic picric acid (PA) in aqueous solution.
