摘要

基于导电聚合物的电致变色/电化学传感器基于电化学和光学技术的结合，提供了分析信号的多模式配准。金属纳米颗粒在导电聚合物薄膜中的应用是改善材料性能的一种方法。为此，将金纳米结构(AuNS)电化学沉积在透明氧化铟锡(ITO)电极上。导电聚合物聚苯胺和聚(3,4-乙二硫代噻吩)薄膜在清洁的AuNS ITO电极上电沉积。评价并比较了掺入AuNS对不同pH下聚合物膜形态和电致变色/光学性能的影响。

Conjugated Polymers and Gold Nanostructures in the Design of Electrochromic/Electrochemical Sensors

Electrochromic/electrochemical sensors based on conducting polymers offer multi-mode registration of analytical signal based on combination of electrochemical and optical techniques. Application of metallic nanoparticles in conducting polymers films can be a way to improve desired properties of the materials. For this purpose gold nanostructures (AuNS) were electrochemically deposited onto transparent indium tin oxide (ITO) electrode. Conducting polymers polyaniline and poly(3,4-ethylenedioxithiophene) films were electrodeposited on clean and pre-modified with AuNS ITO electrode. The effect of incorporated AuNS on polymer film morphology and electrochromic/optical properties at different pH was evaluated and compared.
