【摘要】：长久以来,具备便携性能的高度集成化电化学传感和储能器件吸引了世界范围内广大研究人员的注意。目前电化学传感和储能器件在大规模应用方面的主要限制在于缺少一种快速、方便、低成本的加工手段来将实验室研究成果转化成可以大规模使用的工业产品。喷墨打印作为一种非接触、高精度、按需喷墨的新型加工手段,为电化学传感和储能器件的大规模工业化加工提供了一种可能。本文将喷墨打印加工手段和新型纳米复合材料进行有效结合,制备了具有高灵敏度的电化学传感器芯片和高容量的电化学超级电容器。本论文全面的回顾了喷墨打印的发展史,介绍了导电聚合物及其在喷墨打印方面的应用,也探讨了喷墨打印在传感、储能领域的研究。利用喷墨打印的快速打印、低成本、非接触无污染等优势,探索了喷墨打印在传感方面的研究,其次还探讨了其在超级电容器方面的研究,丰富了喷墨打印的研究内容。本论文主要研究内容归纳如下:1.喷墨印刷制备平面三电极芯片及其在传感上的应用首先,采用以3-巯基丙醇和6-巯基己酸为胶束稳定剂来进行纳米金墨水的合成。主要包括:以贵金属化合物,如氯金酸,与巯基化合物混合,并加入硼氢化钠进行还原,制得稳定的纳米金粒子墨水;利用喷墨印刷的方式印刷纳米金、银电极,经过烧结,然后将银电极放入氯化钠溶液中进行电镀,得到电镀下的银参比电极具有可媲美商用银参比电极的功能;将电极盖上掩膜板,放置于溅射仪器,溅射铂对电极,制得平面三电极。为验证平面三电极芯片的有效性,本课题计划搭载不同的传感器电极材料,对牛奶中的三聚氰胺添加剂和多巴胺进行电化学检测。利用搭载的传感器,对两种物质的电化学的检测结果与商用的的三电极传感体系的检测结果吻合,可以满足日常应用的要求。并且相比于普通的三电极体系,我们制备的平面芯片电极具有更高的灵敏度和更低的检测限。2.喷墨印刷制备柔性可弯曲超级电容器的研究采用改进的Hummers方法制备氧化石墨烯,采用微乳液的方法制备聚苯胺;在冰浴条件下将氧化石墨烯和聚苯胺复合。利用喷墨打印的方式将复合物喷印在金膜基底上,再利用次磷酸将其还原,利用XRD、RAMAN、FT-IR、FESEM、AFM等技术研究了复合物的形貌。然后利用电化学工作站对其超级电容器的电化学性能进行了研究。结果表明:石墨烯与聚苯胺的复合材料用作超级电容器的材料,具有很高的比电容和很好的循环稳定性。
[Abstract]:For a long time, highly integrated and portable electrochemical sensing performance of the storage devices has attracted worldwide attention. Researchers at present electrochemical sensing and storage devices in the large-scale application of main limitation is the lack of a fast, convenient, low cost processing means to translate research results into the laboratory can be used on a large scale industrial inkjet printing products. As a non-contact, high accuracy, a new processing means of on-demand inkjet, large-scale industrial processing for electrochemical energy storage devices and provides a possible. In this paper, ink-jet printing and processing method of novel nano composite materials for effective combination of electrochemical sensor chip with high sensitivity and high the capacity of electrochemical supercapacitors were prepared. This paper reviews the development history of inkjet printing, the conductive polymer and The application of inkjet printing in the ink-jet printing are also discussed in the research field of sensing, energy storage. Using fast printing, inkjet printing and low cost, non pollution, research in the sensing of ink-jet printing, then discusses it in the super capacitor research, enrich the research content of ink-jet printing. The main contents of this dissertation are summarized as follows: 1. the application of inkjet printing preparation of planar three electrode on the sensing chip and the first, using synthetic 3- mercapto propyl alcohol and 6- as stabilizer for thiol caproic acid micelle nano gold ink. Include: precious metal compounds, such as gold chloride acid mixed with thiol compounds, and adding sodium borohydride reduction, the preparation of nano gold particle ink stability; using ink-jet printing method of printing gold nanoparticles, silver electrode after sintering, and then the silver electrode in chloride The plating solution of sodium, get the silver plating parameters with comparable commercial silver reference electrode function than the electrode; the electrode cover mask placed on the sputtering instrument, sputtering platinum electrode, prepared three planar electrode. To validate the planar three electrode chip, this topic plans to carry sensor with different electrodes, electrochemical detection of melamine in milk additives and dopamine. Using sensors, results of electrochemical detection results of two substances and commercial three electrode sensing system that can meet the requirements of daily use. And compared to the three electrode system is normal, the detection limit of us planar chip electrode prepared with higher sensitivity and lower.2. inkjet printing preparation of flexible supercapacitors using improved Hummers method for preparing graphene oxide production Preparation of polyaniline prepared by microemulsion method; under the condition of ice bath in the graphene oxide and polyaniline composite. Using inkjet printing the compound printing on gold substrate, and then use the hypophosphite reduction, using XRD, RAMAN, FT-IR, FESEM, AFM and other technology to study the morphology of complex electrochemical performance of the supercapacitors and electrochemical workstation were studied. The results showed that the composites of graphene and polyaniline used as supercapacitor material, has good cycling performance and high specific capacitance.
