| 초록 |
Polythiophene being a conducting polymer has been studied especially in electrochromism owing to its ease of processibility. In this work polythiophene has been doped with ethyl viologen to fabricate an ECD. The original device which was magenta in color turned transparent when a bias of 1 V was applied and then on increasing the bias to 1.4 V it turned bluish. Subsequently on removal of the bias the original color was restored indicating a reversible nature. Absorption spectroscopy was recorded to note the color contrast value and to perform time derivative study. The current v/s time response was recorded using the Keithley and subsequently typical device parameters were calculated. A switching time of 1/1.1 s (77%, 67%, respectively) at a readout voltage of 1.4 V and a coloration efficiency value of ~275 indicates that the fabricated device shows excellent electrochromic properties. |
