Abstract A study on clay mineral polymer nanocomposites (CPN), namely polyaniline/montmorillonite-cetyltrimethylammonium bromide (PANI/Mt-CTAB), poly o-anisidine/montmorillonite-cetyltrimethylammonium bromide (poly(o-ANIS)/Mt-CTAB) and poly o-anisidine-co-aniline/montmorillonite-cetyltrimethylammonium bromide (poly(o-ANIS-co-ANI)/Mt-CTAB), synthesized by oxidative chemical polymerization method is presented. The nanocomposites have been characterized by Fourier transform infrared spectroscopy, UV–vis spectroscopy, and cyclic voltammetry, X-ray diffraction, scanning electron microscopy, transmission electron microscopy, cyclic voltammetry and thermogravimetry and differential scanning calorimetry analysis. By UV–vis measurements different electronic transitions for the CPNs were pointed out. The voltammograms indicate that the synthetized materials are electroactive. The FTIR analysis reveals the characteristic bands of the polymers and of the Mt-CTAB. The shift of the bands to higher/lower wavenumbers demonstrate the interaction between the pristine polymers macromolecular chains and the montmorillonite (Mt). The intercalation of the polymers inside the mineral clay was confirmed by the increased interlayer distance connected with the position of the 011 diffraction plane of the Mt., and the intercalation and exfoliation states were highlighted in the scanning and transmission electron microscopy images. The obtained results are encouraging in respect with the purpose to use them in the field of photovoltaic applications.

基于蒙脱石改性粘土的导电苯胺和邻茴香胺纳米复合材料的合成与表征

摘要 粘土矿物聚合物纳米复合材料(CPN)的研究,即聚苯胺/蒙脱石-十六烷基三甲基溴化铵(PANI/Mt-CTAB)、聚邻茴香胺/蒙脱石-十六烷基三甲基溴化铵(poly(o-ANIS)/Mt-CTAB)和聚o-茴香胺-co-苯胺/蒙脱石-十六烷基三甲基溴化铵(poly(o-ANIS-co-ANI)/Mt-CTAB),采用氧化化学聚合法合成。纳米复合材料已通过傅里叶变换红外光谱、紫外-可见光谱、循环伏安法、X 射线衍射、扫描电子显微镜、透射电子显微镜、循环伏安法和热重法以及差示扫描量热法进行表征。通过 UV-vis 测量指出了 CPN 的不同电子跃迁。伏安图表明合成的材料具有电活性。FTIR 分析揭示了聚合物和 Mt-CTAB 的特征带。谱带向更高/更低波数的移动证明了原始聚合物大分子链和蒙脱石 (Mt) 之间的相互作用。聚合物在矿物粘土内的插层通过与山的 011 衍射面位置相关的层间距离的增加来证实,并且在扫描和透射电子显微镜图像中突出了插层和剥落状态。所获得的结果对于将它们用于光伏应用领域的目的而言是令人鼓舞的。谱带向更高/更低波数的移动证明了原始聚合物大分子链和蒙脱石 (Mt) 之间的相互作用。聚合物在矿物粘土内的插层通过与山的 011 衍射面位置相关的层间距离的增加来证实,并且在扫描和透射电子显微镜图像中突出了插层和剥落状态。所获得的结果对于将它们用于光伏应用领域的目的而言是令人鼓舞的。谱带向更高/更低波数的移动证明了原始聚合物大分子链和蒙脱石 (Mt) 之间的相互作用。聚合物在矿物粘土内的插层通过与山的 011 衍射面位置相关的层间距离的增加来证实,并且在扫描和透射电子显微镜图像中突出了插层和剥落状态。所获得的结果对于将它们用于光伏应用领域的目的而言是令人鼓舞的。聚合物在矿物粘土内的插层通过与山的 011 衍射面位置相关的层间距离的增加来证实,并且在扫描和透射电子显微镜图像中突出了插层和剥落状态。所获得的结果对于将它们用于光伏应用领域的目的而言是令人鼓舞的。聚合物在矿物粘土内的插层通过与山的 011 衍射面位置相关的层间距离的增加来证实,并且在扫描和透射电子显微镜图像中突出了插层和剥落状态。所获得的结果对于将它们用于光伏应用领域的目的而言是令人鼓舞的。
