This study introduces a novel nanocomposite coating composed of PANI/CeO nanocomposite films, aimed at addressing corrosion protection needs. Analysis through FTIR spectra and XRD patterns confirms the successful formation of the nanocomposite films. Notably, the PANI/CeO nanocomposite films exhibit a hydrophilic nature. The bandgap energy of the PANI composite film is measured to be 3.74 eV, while the introduction of CeO NPs into the PANI matrix reduces the bandgap energy to 3.67 eV. Furthermore, the electrical conductivity of the PANI composite film is observed to be 0.40 S·cm, with the incorporation of CeO NPs leading to an increase in electrical conductivity to 1.07 S·cm. To evaluate its efficacy, electrochemical measurements were conducted to assess the corrosion protection performance. Results indicate a high protection efficiency of 92.25% for the PANI/CeO nanocomposite film.
本研究介绍了一种由聚苯胺/二氧化铈纳米复合薄膜组成的新型纳米复合涂层，旨在满足腐蚀防护需求。通过傅里叶变换红外光谱（FTIR）和X射线衍射（XRD）图谱分析证实了纳米复合薄膜的成功形成。值得注意的是，聚苯胺/二氧化铈纳米复合薄膜具有亲水性。测得聚苯胺复合薄膜的带隙能量为3.74电子伏特，而将二氧化铈纳米颗粒引入聚苯胺基体后，带隙能量降低至3.67电子伏特。此外，观察到聚苯胺复合薄膜的电导率为0.40 S·cm，加入二氧化铈纳米颗粒后电导率增加至1.07 S·cm。为评估其效果，进行了电化学测量以评估腐蚀防护性能。结果表明，聚苯胺/二氧化铈纳米复合薄膜的防护效率高达92.25%。
