Nanocomposites of Poly (3,4-ethylenedioxythiophene) (PEDOT) and surfactant modified Maghnite clay have been successfully synthesized by in situ polymerization of EDOT monomer in the interlayer space of the organoclay. The synthesis has been assisted by ultrasonic method to improve the dispersion of PEDOT polymer between the Maghnite clay sheets. The surfactant modified clay is synthesized via cation exchange method with Hydrogenure Tetrabutylammonuim (TBAHS) and cetyltrimethylammonium (CTAB). Two types of organo-modified clays are obtained namely the Mag-TBA and Mag-CTA according to the template used. Various physico-chemical techniques are used for nanocomposites characterization such as XRD, FTIR, AFM, TGA/DTA, SEM and TEM. The results prove the formation of intercalated / exfoliated upon increasing the content of organoclay in the nanocomposites , consequently, different morphologies and structures in which the exfoliated and intercalated forms were obtained. Both nanocomposites display significant enhancement in the thermal stabilities compared to the PEDOT polymer. However, a decrease in conductivity values is observed for all samples compared to pure conducting polymer. This feature can be improved in view of desired application in electrochemical devices.

使用表面活性剂改性粘土合成和表征聚（3,4-乙烯二氧噻吩）/蒙脱土纳米复合材料

聚（3,4-乙烯二氧噻吩）（PEDOT）纳米复合材料和表面活性剂改性磁铁矿粘土已通过EDOT单体在有机粘土层间空间的原位聚合成功合成。超声方法辅助合成以改善 PEDOT 聚合物在 Maghnite 粘土片之间的分散。表面活性剂改性粘土是通过阳离子交换法与氢四丁基铵（TBAHS）和十六烷基三甲基铵（CTAB）合成的。根据使用的模板，获得了两种类型的有机改性粘土，即 Mag-TBA 和 Mag-CTA。各种物理化学技术用于纳米复合材料的表征，例如 XRD、FTIR、AFM、TGA/DTA、SEM 和 TEM。结果证明，随着纳米复合材料中有机粘土含量的增加，形成了插层/剥落，因此，获得了不同的形态和结构，其中获得了剥落和插层形式。与 PEDOT 聚合物相比，这两种纳米复合材料的热稳定性都显着提高。然而，与纯导电聚合物相比，所有样品的电导率值均有所下降。鉴于在电化学装置中的期望应用，可以改进该特征。与纯导电聚合物相比，所有样品的电导率值均有所下降。鉴于在电化学装置中的期望应用，可以改进该特征。与纯导电聚合物相比，所有样品的电导率值均有所下降。鉴于在电化学装置中的期望应用，可以改进该特征。
