Abstract
Lapisan tipis Polianilin (PANi) telah berhasil dideposisi secara elektrokimia pada elektroda ITO. Proses elektrokimia dilakukan menggunakan variasi scan rate sebesar 10 mV/s, 25 mV/s, 50 mV/s, 75 mV/s, dan 125 mV/s. Variasi scan rate berpengaruh pada warna dan ketebalan lapisan PANi pada permukaan ITO. Semakin besar scan rate menyebabkan warna lapisan PANi semakin pudar. Hasil karakterisasi FTIR telah mengindentifikasi keberadaan fasa emeraldine salt (ES) pada lapisan PANi yang terdeposisi. Sedangkan dari karakterisasi CV memperlihatkan bahwa dengan meningkatnya scan rate akan memperlebar kurva CV lapisan PANi. Kata Kunci: Polianilin, elektrodeposisi, scan rate, ITO Abstract Polyaniline (PANi) thin films have been successfully deposited electrochemically on ITO electrode. The electrochemical process was carried out using variations scan rate of 10 mV/s, 25 mV/s, 50 mV/s, 75 mV/s, and 125 mV/s. Scan rate variations affect the color and thickness of the PANi layer on the ITO surface. The greater scan rate causes the color of the PANi layer to fade. FTIR characterization results have identified the presence of phases emeraldine salt (ES) on the deposited PANi layer. Meanwhile, CV characterization shows that increasing scan rate will widen the CV curve of the PANi layer. Keywords: Polyaniline, electrodeposition, scan rate, ITO
波利尼林尖片(PANi)在ITO电子显微镜下进行电子显微。电子显微镜可提供 10 mV/s、25 mV/s、50 mV/s、75 mV/s 和 125 mV/s 的不同扫描速率。不同的扫描速率会影响到在 ITO 上的电晕和 PANi 片层。如果扫描速率较低,则可能会导致 PANi 厚度较低。傅立叶变换红外光谱仪可以确定翡翠盐 (ES) 在 PANi 片层中的分布情况。从 CV 分析仪中可以了解到,扫描率是否可以提高 PANi 涂料的 CV 值。 Kata Kunci: Polianilin, elektrodeposisi, scan rate, ITO Abstract Polyaniline (PANi) thin films have been successfully deposited electrochemically on ITO electrode.电化学过程的扫描速率分别为 10 mV/s、25 mV/s、50 mV/s、75 mV/s 和 125 mV/s。扫描速率的变化会影响 ITO 表面上 PANi 层的颜色和厚度。扫描速率越大,PANi 层的颜色越淡。傅立叶变换红外特性分析结果表明,在沉积的 PANi 层上存在翡翠盐(ES)相。同时,CV 表征表明,扫描速率的增加会使 PANi 层的 CV 曲线变宽。 关键词聚苯胺、电沉积、扫描速率、ITO
