摘要

全球電子紡織品或稱智慧衣(E-textiles)，每年皆快速在成長中。其中，導電紡織品是E-textiles發展的重要基礎關鍵。有鑒於此，本研究計畫發展出「電致變色電活性蠶絲蛋白複合導電纖維」，使其具有高導電度，並且藉由施加電壓或是酸鹼值控制其顏色。
本研究成功合成出聚苯胺及苯胺四聚體，經由質譜儀與傅立葉轉換紅外線光譜儀(FT-IR)進行結構鑑定，並利用紫外光-可見光分光光譜儀證明其氧化還原特性，且透過循環伏安儀確認其電活性。再者，利用靜電紡絲技術製備出蠶絲奈米纖維，透過調整靜電紡絲參數調整複合纖維的形貌，並加入合成之導電高分子聚苯胺及苯胺四聚體，以增加其導電性及電活性。從研究結果得知，聚苯胺/蠶絲複合纖維電阻值，最低可達到2000歐姆；苯胺四聚體/蠶絲複合纖維電阻值，最低可達到10000歐姆。並透過循環伏安儀，測得此兩種蠶絲複合纖維，皆具有電活性及電致變色現象。

Recently, electronic textiles (E-textiles) have received numerous attention due to their incredible growing rate. Thus, the goal of this research is to develop highly-conductive silk fibroin electrochromic nanofibers for use in E-textiles. The nanofiber is expected to have the capability to change their colors by adjusting the applied voltage or pH value.
In this study, polyaniline (PANI) and tetraaniline (TA) were successfully synthesized. The chemical structures of PANI and TA were confirmed by high -resolution mass spectrometer and Fourier-transform infrared spectroscopy, and the electroactive property was analyzed by cyclic voltammetry. The silk nanofibers were prepared by an electrospinning technique, and the conductive PANI and TA were added to increase the conductivity and electroactive property of the silk composites. The morphology of the composite fibers was controlled by adjusting the electrospinning parameters. The experimental results showed that the PANI/silk composite fiber has a resistance value of 2000 ohms, and the TA/silk composite fiber has a resistance value of 10,000 ohms. Furthermore, both of the developed silk composite fibers possess electroactive and electrochromic properties.
