喷印银奈米板制作电子线路之研究-国立高雄应用科技大学化学工程与.DOCVIP

中文摘要 本論文利用銀奈米板溶液作為噴印墨水，且在聚亞醯胺(Polyimide)基材上噴印形成線寬3.5 mm 金屬導線。本研究重點在於利用銀奈米板作為噴印技術製作銀導線的材料，有別於習用或商業圓球型銀奈米粒子墨水。由四點探針(four-point probe)測量實驗結果顯示，當奈米板噴印，且經低溫100 ℃去除溶劑形成線路後，可得到低電阻導線，與文獻K. Balantrapu , Journal of Materials Research , 25 , 821-827[1]結果相比，圓球型銀奈米粒子線路需150 ℃才能得到低電阻導線。為方便比較，本研究也利用化學還原法合成銀奈米粒子，並製備成噴印墨水，藉由場發射掃描式電子顯微鏡(FE-SEM)觀察這兩種不同樣品發現，板狀的奈米銀在低溫100 ℃去溶劑過程後，比圓球型奈米銀較容易熔融，且板狀粒子分佈上較為均勻，而獲得26.3 μΩ-cm的電阻，圓球型銀粒子為4.3×105 μΩ-cm。此因加溫去溶劑過程，圓球型銀粒子產生嚴重的聚集，且導致分佈不均，而有較大的空隙凹痕產生，造成電阻有過高的狀況。 英文摘要 Ag nanoplates were successfully used as the inkjet particles for printing conductive circuits with 3.5 mm line width on polyimide substrate. In this study, nanoplate ink containing most nanodisks was prepared through the seed-growth method. Printed Ag nanoplates on polyimide substrate were found to easily melted to heat treatment at 100 ℃ for removing ink solvent. The resistivity was measured to 26.3 μΩ-cm by using four-point probe. As for making a benchmark comparison, spherical Ag nanoparticles were prepared and used as ink particles for fabricating electronic circuits. Spherical Ag nanoparticles were melted to conductive circuits of 4.3×105 μΩ-cm at 100 ℃. The ink containing nanoplates yielded the more conductive silver lines than the ink of nanoparticles. 目錄 中文摘要…………………………………………………………………………………………Ⅰ Abstract……………………………………………………………………………………………………………………………………………………………Ⅱ 目錄………………………………………………………………………………………………Ⅲ 表目錄……………………………………………………………………………………………Ⅴ 圖目錄……………………………………………………………………………………………Ⅵ 第一章 研究動機…………………………………………………………………………………1 第二章 文獻回顧…………………………………………………………………………………2 2.1 軟性印刷電路板……………………………………………………………………2 2.1.1 軟板材料的組成…………………………………………………………3 2.1.2 軟板的製備………………………………………………………………8 2.2前瞻性噴墨列印技術………………………………………………………………24 2.2.1 噴印金屬溶液製備金屬導線……………………………………………25 2.2.2 噴印具催化活性之奈米金屬粒子製備金屬導線………………………28 2.3導電機構簡介………………………………………………………………………31 第三章 實驗方法、結果與討論…………………………………………………………………33 3.1 實驗藥品與分析儀器……………………………………………………………33 3
