摘要: | 雷射印表機已被廣泛應用在日常生活中各式文件檔案的列印,它可以提供高列印速率與良好的解析度。其核心技術為靜電複印術,利用施加電場偏壓的方式可以將帶有靜電荷的粉末快速排列並形成圖樣。此印刷技術有著快速、高解析度與全乾式等優點,然而卻鮮少被應用在印刷電子中。在本研究中,我們對靜電複印技術原理作探討,並嘗試利用此技術
導電物質圖樣化,達到製備導電圖案的目的。為了使導電金屬物質能相容於印刷過程,我們以高分子對銅粒子作表面修飾,藉由選用適合的銅粒子並調整高分子種類與含量以提升粉末在印表機元件之間的轉移效率並增進印刷圖案品質,並配合後續光燒結的方式將高分子移除以形成導電通路,在最佳情形下,所印製之圖案的片電阻值為0.25 Ω/□。利用此技術我們在PET、PI與紙等軟性基版上以全乾式的印刷方式快速、大面積的製備出各式高導電度的圖案,展現此技術未來應用在印刷電子的潛力。 Laser printer has been widely used to print various documents in our daily life. It can print pattern not only with high printing speed but also high resolution. The core technology used in laser printing is electrostatic printing technology. It has great advantages of fast speed, high resolution, and dry printing process; however, it is rarely used in printed electronics. In this study, we aim to understand the electrostatic printing process and try to apply commercial laser printer to print conductive material to fabricate conductive patterns. In order to make conductive metal material compatible with electrostatic printing process, the conductive copper powders are modified with polymer. The printed patterns is then treated by subsequent photo sintering process to remove polymer and form conductive pathways. Under optimum conditions, the sheet resistance of the printed conductive film is 0.25 Ω/□. Using this technique, we successfully fabricate various conductive patterns on flexible substrate such as PET, PI, and paper by a dry printing process, demonstrating the potential of this technique to apply to printed electronics. |
