Abstract

This paper investigates the characteristics of poly(pyrrole-co-aniline) copolymer (PYPAN) films deposited by using an atmospheric pressure plasma (APP) polymerization relative to various concentrations of aniline and pyrrole monomers. The surface morphology and structure properties of PYPAN films are observed to strongly depend on the pyrrole concentration (%), which is confirmed by Field emission-scanning electron microscopy (FE-SEM), Fourier transforms-infrared spectroscopy (FT-IR), X-ray photoelectron spectroscopy (XPS), and time of flight-secondary ion mass spectrometry (ToF-SIMS). In particular, it is observed that the PYPAN film grown at an optimal pyrrole concentration condition (that is, aniline 25% and pyrrole 75%) shows a lower electrical resistance and higher deposition rate.

摘要

本文研究了使用大气压等离子体 (APP) 聚合沉积的聚 (吡咯-苯胺) 共聚物 (PYPAN) 薄膜相对于各种浓度的苯胺和吡咯单体的特性。观察到 PYPAN 薄膜的表面形态和结构特性强烈依赖于吡咯浓度 (%)，这通过场发射扫描电子显微镜 (FE-SEM)、傅里叶变换红外光谱 (FT-IR)、X射线光电子能谱 (XPS) 和飞行时间-二次离子质谱 (ToF-SIMS)。特别是，观察到在最佳吡咯浓度条件（即苯胺 25% 和吡咯 75%）下生长的 PYPAN 薄膜显示出较低的电阻和较高的沉积速率。
