【摘要】：近年來(lái),利用印刷電子技術(shù)制備半導(dǎo)體器件和導(dǎo)電線路越來(lái)越受到人們重視,而噴墨打印技術(shù)作為印刷電子技術(shù)中的重要組成部分受到廣泛關(guān)注。本文主要工作包括自主制備出性能穩(wěn)定,形貌統(tǒng)一的納米銀顆粒,并將其配置成可噴墨打印導(dǎo)電油墨;進(jìn)行單層和多層導(dǎo)電線路打印實(shí)驗(yàn),研究和優(yōu)化實(shí)驗(yàn)條件及打印機(jī)參數(shù)設(shè)置,得到打印銀(Ag)線最佳性能。(1)分別制備出兩種不同保護(hù)劑的納米銀顆粒,并對(duì)產(chǎn)物進(jìn)行表征,測(cè)得保護(hù)劑為聚丙烯酸的納米銀粒徑約20 nm,保護(hù)劑為十二胺的納米銀粒徑約50 nm;由于聚丙烯酸屬于水溶性材料,在銀顆粒表面屬于弱吸附容易去除,因此選擇聚丙烯酸做保護(hù)劑制備的納米顆粒制備導(dǎo)電油墨,添加相關(guān)助劑以改善噴墨性能;(2)同時(shí),選擇環(huán)氧樹(shù)脂板、相片紙、聚對(duì)苯二甲酸乙二醇酯等做基底進(jìn)行打印實(shí)驗(yàn),并對(duì)基底進(jìn)行表面改性,提高打印線路附著性和導(dǎo)電圖案分辨率。單獨(dú)分析環(huán)氧樹(shù)脂板做基底的打印成膜性及克服咖啡環(huán)效應(yīng)的實(shí)驗(yàn)條件,并對(duì)導(dǎo)電機(jī)理進(jìn)行研究,探討燒結(jié)溫度、打印層數(shù)、燒結(jié)時(shí)間與樣品電阻率的關(guān)系。以相片紙做基底,110℃條件下燒結(jié)1 h,可獲得電阻率為8μΩ·cm的導(dǎo)線;(3)最后將旋涂技術(shù)與噴墨打印技術(shù)相結(jié)合,以聚對(duì)苯二甲酸乙二醇酯做基底,聚甲基丙烯酸甲酯作絕緣層,進(jìn)行多層電路制備實(shí)驗(yàn)的探索,為該課題下一步研究提供參考。
[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.
