Abstract In this study, sulfuric acid (H2SO4)-doped novel binary copolymer films using aniline and haloanilines as monomers, including aniline/o-fluoro-aniline (PFANI), aniline/o-chloro-aniline (PCANI), and aniline/o-bromo-aniline (PBANI), have been constructed for electro-emissive devices (EEDs). Significantly different electropolymerization behaviors, surface micromorphologies and infrared (IR) emissivity regulation ability are observed by these copolymer films. The results show that PFANI film exhibits the highest IR emissivity modulation capability. The nucleation process and surface morphology of copolymer films are explained by the theory of atomic electronegativity. High emissivity changes (△e) of 0.113, 0.417 and 0.343 in the wavelength ranges of 3–5 μm, 8–14 μm, and 2.5–25 μm, respectively, are obtained by PFANI film. The EEDs based on PFANI films show promising applications in IR thermal control, and dynamic visible light and IR camouflage.

用于电发射器件的新型苯胺和卤代苯胺二元共聚物薄膜

摘要 在本研究中，以苯胺和卤代苯胺为单体的硫酸 (H2SO4) 掺杂新型二元共聚物薄膜，包括苯胺/邻氟苯胺 (PFANI)、苯胺/邻氯苯胺 (PCANI) 和苯胺/邻苯胺。 -溴苯胺 (PBANI)，已构建用于电发射设备 (EED)。这些共聚物膜观察到显着不同的电聚合行为、表面微形态和红外 (IR) 发射率调节能力。结果表明，PFANI 薄膜表现出最高的红外发射率调制能力。共聚物薄膜的成核过程和表面形貌用原子电负性理论解释。PFANI 薄膜在 3-5 μm、8-14 μm 和 2.5-25 μm 的波长范围内分别获得了 0.113、0.417 和 0.343 的高发射率变化（△e）。
