Anion exchange membranes (AEMs) are of particular interest due to their properties that allow for the selective conductivity of anions, which is essential for efficient operation of electrochemical devices. Recently, quaternized poly(ether ether ketone) (QDPEEK) has gained increasing attention as a promising material for the preparation of AEMs. However, there is still room for improvement in terms of the preparation and modification of QDPEEK AEMs in order to optimize their properties.Objectives:The objectives of this project are:1. To prepare QDPEEK AEMs using a solution-casting method and evaluate their physicochemical properties.2. To modify the surface properties of QDPEEK AEMs through either chemical or physical means and evaluate the effects on their performance.3. To investigate the electrochemical performance of the modified QDPEEK AEMs in alkaline fuel cells.Methods:The QDPEEK AEMs will be prepared by solution-casting, using a mixture of QDPEEK and an appropriate inorganic filler as the casting solution. The physicochemical properties of the resulting membranes will be evaluated by various techniques, such as SEM, XRD, FTIR, and contact angle measurement. The surface of the QDPEEK AEMs will then be modified chemically or physically by different methods, such as plasma treatment, grafting, and layer-by-layer assembly. The effects of the surface modification on the properties of the QDPEEK AEMs will be evaluated by various techniques, such as wettability, ion exchange capacity, and thermal stability. Finally, the modified 精品文档---下载后可任意编辑QDPEEK AEMs will be evaluated for their electrochemical performance in alkaline fuel cells.Expected outcomes:It is expected that the QDPEEK AEMs prepared in this project will exhibit high ion exchange capacity, good mechanical strength, and thermal stability. Furthermore, the surface modification of the QDPEEK AEMs is expected to improve their stability, wettability, and ion conductivity. The electrochemical performance of the modified QDPEEK AEMs in alkaline fuel cells is expected to show improved power density and durability. These outcomes will demonstrate the potential of QDPEEK AEMs as promising materials for electrochemical devices.Conclusion:In conclusion, the preparation and modification of QDPEEK AEMs will be investigated in this project with the aim of optimizing their properties for use in electrochemical devices. The expected outcomes will contribute to the development of more efficient and durable electrochemical devices for clean energy applications.
