摘要:
以单壁碳纳米管（SWCNTs）为基体，掺入适量的植酸、苯胺与过硫酸铵，通过原位溶液聚合制得植酸掺杂聚苯胺/酸化单壁碳纳米管（PA/PANI/SWCNTs）热电复合薄膜。通过扫描电子显微镜、傅里叶变换红外光谱、拉曼光谱、X-射线衍射、X-光电子能谱、热重分析和热电仪器表征了复合薄膜的结构与性能。结果表明：植酸掺杂聚苯胺为珊瑚状形貌，掺入适量的植酸掺杂聚苯胺和适当的提升温度有助于提升单壁碳纳米管基热电薄膜的功率因子。当植酸掺杂聚苯胺与酸化单壁碳纳米管的质量比为2∶10，温度为125 ℃时，PA/PANI/SWCNTs的功率因子最高，为（95.9±1.5） μW/（m·K2），对应的Seebeck系数和电导率分别为（44.5±0.5） μV/K和（48.4±0.3） kS/m。

Abstract:
Single-walled carbon nanotubes （SWCNTs） were used as matrix， and phytic acid-doped polyaniline/single-walled carbon nanotubes （PA/PANI/SWCNTs） thermoelectric composite thin films were prepared by in-situ solution polymerization. The structures and properties of the composite films were characterized by scanning electron microscopy，Fourier transform infrared spectroscopy，Raman spectroscopy，X-ray diffractometry，X-ray photoelectron spectroscopy，thermogravimetric analysis and thermoelectric instrument analysis. The experimental results showed that phytic acid-doped polyaniline has coral-like morphology. Mixing a proper amount of phytic acid polyaniline and appropriately increasing temperature can improve the power factor of SWCNTs-based thermoelectric thin films. The maximum power factor of PA/PANI/SWCNTs is （95.9±1.5） μW/（m·K2） when the mass ratio of PA/PANI to A-SWCNTs is 2∶10 at 125 ℃，and the Seebeck coefficient is （44.5±0.5） μV/K，and the electrical conductivity is （48.4±0.3） kS/m.
