阐述了等离子体化学无溶剂法沉积掺杂聚苯胺基(PANI基)导电涂料及纳米复合导电涂料的方法。采用傅立叶变换红外光谱、紫外可见光谱、阻抗谱和透射电子显微镜等手段对聚苯胺涂层的分子结构、形貌、光学、电学和传感性能进行了研究。合成的含银纳米粒子的PANI基涂层具有部分掺杂结构，氧化和还原PANI单元的尺寸变化很小。将纳米复合PANI基涂层沉积在叉指电容器上，用于氨气传感。特别是在阻抗谱的低频区，银纳米粒子对PANI基涂层传感性能的提高起到了促进作用。在氨浓度高达10ppm的直流和交流电压下，检测了该传感器响应的高灵敏度和线性。
The plasma chemical solvent-free method of doped and nanocomposite polyaniline-based (PANI-based) conductive coatings deposition was elaborated. Molecular structure, morphology, optical, electrical and sensing properties of PANI-based coating were investigated by Fourier transform infrared, UV-vis, impedance spectroscopy methods and transmittance electron microscopy. The synthesized PANI-based coatings containing silver nanoparticles have a partially doped structure with low variation in size of oxidized and reduced PANI units..The nanocomposite PANI-based coatings were deposited onto interdigital capacitor for ammonia gas sensing applications. The increasing of the sensing performance of the PANI-based coatings with silver nanoparticles was established in particular at the low frequency region of impedance spectra. The high sensitivity and linearity of this sensor response were examined at a direct and alternating voltage with ammonia concentrations up to 10 ppm.
