本研究提出一種新穎製程用以製造奈米銀導電乙醇墨水的奈米銀棒，我們使用晶種合成法以UV曝光後的奈米氯化銀顆粒作為晶種，在120℃環境下加入聚乙烯吡咯烷酮(PVP)及硝酸銀合成高展弦比約1055的奈米銀線溶液，在室溫下利用磁石攪拌通過孔隙率94.8%平均孔洞大小約2mm的多孔性發泡鋁，經4天後得到展弦比約130的奈米銀棒，利用奈米銀棒調配25wt%臨界濃度的奈米銀導電乙醇墨水，以鋼筆在紙張上繪製成寬度為1毫米的導電線段，其片電阻約為0.018Ω/sq。 The present study has been purposed a novel process for manufacturing conductive ink consists of silver nanorods with ethanol and coated it on the paper to a conductive line with low sheet resistance. First, we synthesized the silver nanowires solution using the irradiated nano silver chloride particles by UV irradiation as a seed crystal and seed synthesis method. Then the silver nanowires solution was magnetic agitated and passed through a foamed aluminum with porosity about 95% and average pore size about 2mm at 25°C for 96 hours. The average aspect ratio of silver nanowires will be decreased from 1055 to 130 via. silver nanowires were chopped by erosion with foamed aluminum and we fabricated successful a conductive ink which consist of 26wt% of ethanol mixed with nano silver rods and then coated a conductive line with width of 1mm on the matte paper by pen which the sheet resistance of conductive line reached 0.018 Ω/sq.
