| 摘 要： | 采用电化学方法，利用有机染料对聚苯胺进行有机染料增感，制备出不同增感性能的聚苯胺薄膜。采用红外吸收光谱对增感后的聚苯胺的结构和性能进行了表征，对其在紫外－ 可见光区的吸收特性进行了研究。结果表明，染料增感后的聚合物薄膜电导率分别为：直接耐晒蓝增感为０ ．１４２ Ｓ／ｃｍ ；直接耐晒翠蓝增感为１ ．０５０ Ｓ／ｃｍ ；直接耐晒黑增感为０ ．７９６ Ｓ／ｃｍ ； 四羧基酞菁增感为１ ．２２０ Ｓ／ｃｍ 。这些增感均可使聚苯胺在可见光谱范围内的光吸收增强，较大幅度地改善聚苯胺的光谱响应范围，并使得有机染料增感后的聚苯胺薄膜保持很高的电导率

| Abstract: | In this paper, sensitization of polyaniline with dyes by electrochemical polymerization is presented. HClO 4 is employed as the dopant and oxidant. The polyaniline with different structure and properties is synthesized. The effect of sensitized emeraldine salt on the absorption spectra is discussed in details. The photoconductivity of polyaniline can be enhanced by using these sensitized dyes. Therefore, mixture of sensitive material is advantageous to the absorption of polyaniline in visible light spectrum. |
