AbstractIn this work, new nanoclay composites were prepared through in situ polymerization for reported conducting polyarylidenes based on cyclopentanone and cyclohexanone moieties in the main chain. Additionally, a novel conducting polymer (CP), based on cycloheptanone, was synthesized along with its nanoclays. The studied materials were characterized via Fourier transform infrared spectroscopy (FTIR), X-ray diffraction, scanning electron microscopy (SEM), and transmission electron microscopy (TEM). The main objective was to study the effect of nanoclay modification and ring size on CP solubility, thermal behavior, optical properties, and corrosion inhibition effects. The obtained results showed enhanced solubility and thermal stability of the nanocomposites compared to their original CPs. Moreover, all materials emitted efficiently in the solid state with luminescence enhancement and dependence on aggregation. Furthermore, these CPs and their nanoclays were checked as corrosion inhibitors against mild steel dissolution in acidic media. Cycloheptanone nanocomposites showed the highest inhibition efficiency (95.92%), confirming that the presence of nanoclays can enhance the CP’s ability to retard the corrosion by covering more surface area of the metal. This study presents ways to enhance the solubility, thermal stability, and corrosion inhibition efficiency of CPs using nanoclay modification. Additionally, these nanoclays may be used as solid-state luminescent materials and mixed inhibitors.Conducting polymers were synthesized via in situ polymerization, using nanoclay bentonite sodium and its modified form. The polymer nanoclay modified form showed enhanced solubility compared to the original polymers and improved thermal stability, along with higher corrosion inhibition efficiency and aggregation-induced emission with luminescence dependent on the aggregate structure.

摘要在这项工作中，通过原位聚合制备了新型纳米粘土复合材料，用于报道基于主链环戊酮和环己酮部分的导电聚芳叉。此外，还合成了一种基于环庚酮的新型导电聚合物 (CP) 及其纳米粘土。通过傅里叶变换红外光谱 (FTIR)、X 射线衍射、扫描电子显微镜 (SEM) 和透射电子显微镜 (TEM) 对研究的材料进行表征。主要目的是研究纳米粘土改性和环尺寸对 CP 溶解度、热行为、光学性质和腐蚀抑制效果的影响。所得结果表明，与原始 CP 相比，纳米复合材料的溶解性和热稳定性有所提高。而且，所有材料在固态下都能有效发射，发光增强并依赖于聚集。此外，这些 CP 及其纳米粘土被检查作为腐蚀抑制剂，防止低碳钢在酸性介质中溶解。环庚酮纳米复合材料显示出最高的抑制效率 (95.92%)，证实纳米粘土的存在可以通过覆盖更多的金属表面积来增强 CP 延缓腐蚀的能力。本研究提出了使用纳米粘土改性来提高 CPs 的溶解性、热稳定性和腐蚀抑制效率的方法。此外，这些纳米粘土可用作固态发光材料和混合抑制剂。导电聚合物是通过原位聚合合成的，使用纳米粘土膨润土钠及其改性形式。
