Vertically aligned zinc oxide (ZnO) nanorods have been fabricated on a polyaniline (PANI) film template after electrochemical seeding and hydrothermal growth in a nutrient medium at a low temperature of 65 °C. Dense c-oriented [0001], hexagonal-shaped, vertically aligned ZnO nanorods are obtained on the PANI film surface, which is confirmed by X-ray diffraction and scanning electron microscopy studies. The nanohybrid film used as the working electrode has been characterized for sensing catechin polyphenol in different tea varieties through cyclic voltammetry. Principal component analysis shows enhancement in the classification ability of the nanohybrid film for various concentrations of catechin standard and tea infusions.
在聚吡咯（PANI）薄膜模板上，通过电化学种晶和在营养介质中于低温 65°C 下的水热生长，制备了垂直排列的氧化锌（ZnO）纳米棒。在 PANI 薄膜表面上获得了密集的 c 取向的[0001]、六方形状的、垂直排列的 ZnO 纳米棒，这通过 X 射线衍射和扫描电子显微镜研究得到了证实。用作工作电极的纳米杂化薄膜已通过循环伏安法对不同品种茶叶中的儿茶素多酚进行了传感特性表征。主成分分析表明，纳米杂化薄膜对儿茶素标准品和茶浸液的各种浓度的分类能力得到了增强。
