To obtain better thermal shielding and more compact aerogel fabrics, ultrafine, highly flexible and easily bendable aerogel fibers have been developed, called ultrafine Kevlar aerogel fibers (UKAF). These fibers are observed to be about 100 μm in diameter, finer than reported in most previous studies, and perform well in tensile and heat resistance. The breaking strength of the UKAFs can be as high as 6.5 MPa, thanks to the use of high-concentration spinning suspensions. Besides, these ultrafine fibers also inherit the excellent thermal stability of Kevlar, almost do not decompose before 480 °C. In addition, the resultant UKAFs can be easily twisted, knotted, and braided. The fabrics braided from such fibers are able to show a significant temperature drop gradient of 130 °C mm when exposed to a hot plate of 300 °C, indicating superb performance in thermal insulation. Given these, the flexible UKAFs prepared in this study that possess a distinctive set of properties will be highly advantageous across various applications, particularly in the field of thermal insulation.","PeriodicalId":18322,"journal":{"name":"Materials Today Sustainability","volume":null,"pages":null},"PeriodicalIF":7.8,"publicationDate":"2024-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141613176","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

At present, traditional technologies are difficult to detect and remove existing trace emerging contaminants in water bodies. Therefore, efficient removal of low concentration emerging contaminants is a key issue in ensuring water safety. As an emerging technology, molecular imprinting technology (MIT) can synthesize polymers with specific recognition ability for target pollutants, providing a new approach for efficient removal of emerging contaminants. It is worth noting that combining MIT with traditional catalysts is an effective method to improve detection limits and removal efficiency. This review mainly introduced the research progress of using MIT to detect pollutants in various sensors and using advanced oxidation technology to remove pollutants in recent years, focusing on the preparation and application of MIT-based photocatalysts, electrocatalysts, and Fenton-like catalysts. In addition, possible interactions between the target analyte and MIT were discussed, as well as the reusability and stability of imprinted catalysts in water treatment, and their potential ecological toxicity risks were analyzed. Finally, the challenges of MIT based pollutant mitigation and the application prospects of molecular imprinting technology in environmental analysis were elaborated from multiple perspectives.","PeriodicalId":18322,"journal":{"name":"Materials Today Sustainability","volume":null,"pages":null},"PeriodicalIF":7.8,"publicationDate":"2024-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141613178","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
