Pure and varying weigh ratio of SmO-TiO modified polyaniline nanocomposite has been successfully synthesized using in situ polymerization of aniline solution with SmO-TiO binary oxide. The nanocomposite have been characterized by X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FT-IR), X-photoelectron microscopy (XPS), Field emission-scanning electron microscope (FE-SEM), transmission electron microscopy (TEM) thermogravimetric analysis (TGA) and LCR meter. The XRD results show synthesis anatase TiO phase with tetragonal structure and (monoclinic and cubic) mixture structure of SmO. The FE-SEM and TEM measurements appear preparing spherical nanoparticles that covered fiber morphology of polyaniline and successfully in situ polymerization process. The TGA measurements are obtain high thermal stability for polyaniline after incorporation by SmO-TiO binary oxide nanoparticles. LCR measurement is obtained that the DC conductivity, dielectric constant and dielectric loss of nanocomposite is larger than pure polyaniline and the electric properties increase with increasing the concentration of nanoparticles.
已成功使用 SmO-TiO 二元氧化物的苯胺溶液原位聚合,合成了具有纯和变化的 SmO-TiO 改性聚苯胺纳米复合材料的重量比。通过 X 射线衍射(XRD)、傅里叶变换红外光谱(FT-IR)、X 光电子能谱(XPS)、场发射扫描电子显微镜(FE-SEM)、透射电子显微镜(TEM)、热重分析(TGA)和 LCR 仪表对纳米复合材料进行了表征。XRD 结果表明,合成了具有四方结构和(单斜和立方)SmO 混合结构的锐钛矿 TiO 相。FE-SEM 和 TEM 测量表明,制备了覆盖聚苯胺纤维形态的球形纳米粒子,并成功地进行了原位聚合过程。TGA 测量表明,聚苯胺在掺入 SmO-TiO 二元氧化物纳米粒子后具有较高的热稳定性。LCR 测量表明,纳米复合材料的直流电导率、介电常数和介电损耗均大于纯聚苯胺,并且随着纳米粒子浓度的增加,电性能也随之增加。
