Novel flexible freestanding films of polyaniline–polycarboxylate ether nanocomposites (PAni–PCE NCs) were first synthesized effectively by a one-step in-situ polymerization of aniline in the presence of recent generation superplasticizer PCE as a polyanionic dopant cum film-forming agent. Various spectrochemical methods were used to characterize the molecular structures of the produced PAni–PCE NCs. In this work, PAni–PCE NCs show the lattice fringes structures by HR–TEM study for the first time. The electrical conductivity of flexible freestanding PAni–PCE nanocomposite films was measured using a four-probe method. The maximum conductivity was found in the range of 1.5 S cm⁻¹ for PAni–PCE5 nanocomposite film. FT–IR results confirmed that PAni had been successfully doped or incorporated into the PCE matrix. The XRD pattern validated the crystalline nature of novel flexible freestanding PAni–PCE nanocomposite films. By increasing the concentration of PCE from 0.033 M to 0.165 M, the morphological transition from nanorods to nanosheets and nanoneedles was observed in the SEM image of the flexible freestanding PAni–PCE NCs film. From the TGA result, flexible freestanding PAni–PCE nanocomposite films showed higher thermal stability than pure PAni.

聚苯胺-聚羧酸酯醚纳米复合材料（PAni-PCE NCs）的新型柔性独立薄膜首先通过苯胺的一步原位聚合在新一代减水剂PCE作为聚阴离子掺杂剂兼成膜剂的存在下有效合成。使用各种光谱化学方法来表征生产的 PAni-PCE NCs 的分子结构。在这项工作中，PAni-PCE NC 首次通过 HR-TEM 研究显示了晶格条纹结构。使用四探针法测量柔性独立式 PAni-PCE 纳米复合薄膜的电导率。在 1.5 S cm ^-1范围内发现最大电导率用于 PAni-PCE5 纳米复合薄膜。FT-IR 结果证实 PAni 已成功掺杂或掺入 PCE 基质中。XRD 图案验证了新型柔性独立式 PAni-PCE 纳米复合薄膜的结晶性质。通过将 PCE 的浓度从 0.033 M 增加到 0.165 M，在柔性独立式 PAni-PCE NCs 薄膜的 SEM 图像中观察到从纳米棒到纳米片和纳米针的形态转变。从 TGA 的结果来看，柔性独立式 PAni-PCE 纳米复合薄膜表现出比纯 PAni 更高的热稳定性。
