发布时间:2018-08-16 12:47
【摘要】:近年来,利用印刷电子技术制备半导体器件和导电线路越来越受到人们重视,而喷墨打印技术作为印刷电子技术中的重要组成部分受到广泛关注。本文主要工作包括自主制备出性能稳定,形貌统一的纳米银颗粒,并将其配置成可喷墨打印导电油墨;进行单层和多层导电线路打印实验,研究和优化实验条件及打印机参数设置,得到打印银(Ag)线最佳性能。(1)分别制备出两种不同保护剂的纳米银颗粒,并对产物进行表征,测得保护剂为聚丙烯酸的纳米银粒径约20 nm,保护剂为十二胺的纳米银粒径约50 nm;由于聚丙烯酸属于水溶性材料,在银颗粒表面属于弱吸附容易去除,因此选择聚丙烯酸做保护剂制备的纳米颗粒制备导电油墨,添加相关助剂以改善喷墨性能;(2)同时,选择环氧树脂板、相片纸、聚对苯二甲酸乙二醇酯等做基底进行打印实验,并对基底进行表面改性,提高打印线路附着性和导电图案分辨率。单独分析环氧树脂板做基底的打印成膜性及克服咖啡环效应的实验条件,并对导电机理进行研究,探讨烧结温度、打印层数、烧结时间与样品电阻率的关系。以相片纸做基底,110℃条件下烧结1 h,可获得电阻率为8μΩ·cm的导线;(3)最后将旋涂技术与喷墨打印技术相结合,以聚对苯二甲酸乙二醇酯做基底,聚甲基丙烯酸甲酯作绝缘层,进行多层电路制备实验的探索,为该课题下一步研究提供参考。
[Abstract]:In recent years, more and more attention has been paid to the preparation of semiconductor devices and conductive circuits by printing electronics technology. Inkjet printing technology, as an important part of printing electronics technology, has attracted wide attention. Printing conductive ink; single-layer and multi-layer conductive circuit printing experiments, research and optimize the experimental conditions and printer parameters settings, get the best performance of printed silver (Ag) line. (1) Two kinds of nano-silver particles with different protective agents were prepared, and the products were characterized. The particle size of nano-silver with polyacrylic acid was about 20 nm, and the protective agent was determined. The particle size of nano-silver dodecylamine is about 50 nm; because polyacrylic acid is a water-soluble material, it is easy to be removed by weak adsorption on the surface of silver particles, polyacrylic acid is chosen as a protective agent to prepare conductive ink, and relevant additives are added to improve the ink-jet performance; (2) At the same time, epoxy resin board, photo paper and poly (terephthalic acid) are selected. Ethylene glycol ester was used as the substrate for printing experiment, and the substrate was modified to improve the adhesion of printing circuit and the resolution of conductive pattern. The relationship between the resistivity and the sample resistivity is studied. The 8_ cm resistivity can be obtained by sintering the photo paper at 110 C for 1 h. (3) Finally, the spin-coating technology is combined with the inkjet printing technology, and the experiment of multi-layer circuit preparation using polyethylene terephthalate as the substrate and polymethyl methacrylate as the insulating layer is explored. The next step is to provide reference.
