【摘要】：長(zhǎng)久以來(lái),具備便攜性能的高度集成化電化學(xué)傳感和儲(chǔ)能器件吸引了世界范圍內(nèi)廣大研究人員的注意。目前電化學(xué)傳感和儲(chǔ)能器件在大規(guī)模應(yīng)用方面的主要限制在于缺少一種快速、方便、低成本的加工手段來(lái)將實(shí)驗(yàn)室研究成果轉(zhuǎn)化成可以大規(guī)模使用的工業(yè)產(chǎn)品。噴墨打印作為一種非接觸、高精度、按需噴墨的新型加工手段,為電化學(xué)傳感和儲(chǔ)能器件的大規(guī)模工業(yè)化加工提供了一種可能。本文將噴墨打印加工手段和新型納米復(fù)合材料進(jìn)行有效結(jié)合,制備了具有高靈敏度的電化學(xué)傳感器芯片和高容量的電化學(xué)超級(jí)電容器。本論文全面的回顧了噴墨打印的發(fā)展史,介紹了導(dǎo)電聚合物及其在噴墨打印方面的應(yīng)用,也探討了噴墨打印在傳感、儲(chǔ)能領(lǐng)域的研究。利用噴墨打印的快速打印、低成本、非接觸無(wú)污染等優(yōu)勢(shì),探索了噴墨打印在傳感方面的研究,其次還探討了其在超級(jí)電容器方面的研究,豐富了噴墨打印的研究?jī)?nèi)容。本論文主要研究?jī)?nèi)容歸納如下:1.噴墨印刷制備平面三電極芯片及其在傳感上的應(yīng)用首先,采用以3-巰基丙醇和6-巰基己酸為膠束穩(wěn)定劑來(lái)進(jìn)行納米金墨水的合成。主要包括:以貴金屬化合物,如氯金酸,與巰基化合物混合,并加入硼氫化鈉進(jìn)行還原,制得穩(wěn)定的納米金粒子墨水;利用噴墨印刷的方式印刷納米金、銀電極,經(jīng)過(guò)燒結(jié),然后將銀電極放入氯化鈉溶液中進(jìn)行電鍍,得到電鍍下的銀參比電極具有可媲美商用銀參比電極的功能;將電極蓋上掩膜板,放置于濺射儀器,濺射鉑對(duì)電極,制得平面三電極。為驗(yàn)證平面三電極芯片的有效性,本課題計(jì)劃搭載不同的傳感器電極材料,對(duì)牛奶中的三聚氰胺添加劑和多巴胺進(jìn)行電化學(xué)檢測(cè)。利用搭載的傳感器,對(duì)兩種物質(zhì)的電化學(xué)的檢測(cè)結(jié)果與商用的的三電極傳感體系的檢測(cè)結(jié)果吻合,可以滿足日常應(yīng)用的要求。并且相比于普通的三電極體系,我們制備的平面芯片電極具有更高的靈敏度和更低的檢測(cè)限。2.噴墨印刷制備柔性可彎曲超級(jí)電容器的研究采用改進(jìn)的Hummers方法制備氧化石墨烯,采用微乳液的方法制備聚苯胺;在冰浴條件下將氧化石墨烯和聚苯胺復(fù)合。利用噴墨打印的方式將復(fù)合物噴印在金膜基底上,再利用次磷酸將其還原,利用XRD、RAMAN、FT-IR、FESEM、AFM等技術(shù)研究了復(fù)合物的形貌。然后利用電化學(xué)工作站對(duì)其超級(jí)電容器的電化學(xué)性能進(jìn)行了研究。結(jié)果表明:石墨烯與聚苯胺的復(fù)合材料用作超級(jí)電容器的材料,具有很高的比電容和很好的循環(huán)穩(wěn)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.
