摘要

为获得优异性能的纳／微米结构的有机-无机复合功能材料，进而探讨在纳／微米结构的电子器件或其它领域的潜在应用，在纳米线聚苯胺（PANi）悬浮液的存在下，采用水热方法进行了ZnO 的生长，并用所制得的ZnO／PANi 复合材料构筑了叉指结构的聚合物基柔性化学传感器原型器件。采用透射电镜（TEM）、X 射线衍射（XRD）、X 射线光电子能谱（XPS）等进行了表征，对原型器件的部分响应特性进行了对比考察。结果表明，所制得的ZnO／PANi 复合材料为纳米线结构，ZnO 的存在对原型器件的敏感特性有明显的影响，影响到聚苯胺的质子化-去质子化过程。XPS 结果显示，ZnO／PANi 复合对ZnO 中Zn、O 元素的结合能有显著的影响。所有这些初步结果表明，ZnO／PANi 间可能存在强的相互作用，很可能发生了从PANi 到ZnO 界面间的电荷转移。

Abstract

In order to obtain nano/micro-structured organic-inorganic composite with unique properties for nanoelectronic/microelectronic device applications

a study on growth of ZnO using hydrothermal synthesis approach in the presence of suspension containing polyaniline nanowires was carried out.A series of characterizations were examined by transmission electron microscopy(TEM)

the Fourier-Transform Infrared spectra(FTIR)

X-ray diffraction(XRD)

X-ray photoelectron spectroscopy (XPS)

etc.The results indicated that the resulting-product was ZnO/PANi composite nanowire structure.The charge transfer was possibly taken place at the interface between ZnO and polyaniline nanowire.A chemical prototype sensor was constructed based on ZnO/PANi composite nanowire and an interdigital electrodes on flexible polymer substrate.The gas-sensing behaviors of the sensor to ammonia and HCI gas at room temperature were investigated.Results showed that the effects of the presence of ZnO on the sensitivity of polyaniline based chemical sensors were remarkably.This proved further that the strong interaction between ZnO and polyaniline was existed.
