摘要

本研究旨在将所制备的聚合物纳米复合材料应用于固态光电器件领域。采用原位化学聚合的方法,将铁纳米粒子与合成的无规共聚聚酯(BCTP)和聚吡咯结合,制备了聚合物纳米复合材料。由于其查尔酮部分的存在,所合成的随机共聚酯具有广泛的生物活性,其应用也可扩展到光电子领域。用傅里叶红外光谱(FTIR)等光谱分析方法确定了共聚聚酯(BCTP)的化学结构取向。采用傅里叶变换红外光谱(FTIR)和粉末x射线衍射(PXRD)对铁纳米粒子、聚吡咯和聚合物纳米复合材料进行了表征。FTIR光谱证实了聚合物纳米复合材料的形成,从起始材料的拉伸频率显著变化。采用粉末x射线衍射法测定了铁纳米粒子的平均晶粒尺寸。利用扫描电镜对铁纳米粒子、聚吡咯和聚合物纳米复合材料的结构形态进行了表征。SEM图像显示铁纳米颗粒,聚吡咯位于聚合物基体中。循环伏安分析表明,该聚合物纳米复合材料的比电容为58.88 F/g。通过阻抗分析研究了随机共聚酯(BCPT)、铁纳米粒子、聚吡咯和聚合物纳米复合材料的电化学行为。这证实了聚合物纳米复合材料具有良好的导电性质,离子电导率为6.89 × 10-5 S cm-1。

ELECTRICAL PROPERTIES ON COPOLYESTER INCORPORATED IN A POLYMER NANOCOMPOSITE MATRIX - A STUDY
This study aims at the application of the prepared Polymer Nanocomposite in the field of solid-state optoelectronic devices. Polymer Nanocomposite was prepared by incorporating iron nanoparticles, synthesized random Copolyester (BCTP), and Polypyrrole by Insitu chemical polymerization method. The application of the synthesized random Copolyester with wide biological activity due to bis chalcone moiety can also be extended to the optoelectronics field. The Copolyester (BCTP) was subjected to spectral analysis such as Fourier Transform Infrared Spectroscopy (FTIR) to confirm the chemical structural orientation. The Iron nanoparticles, Polypyrrole, and polymer nanocomposite were characterized by Fourier Transform Infrared Spectroscopy (FTIR) and powder X-ray Diffraction (PXRD). The FTIR spectroscopy confirms the formation of polymer nanocomposite by the prominent shift in stretching frequency from the starting materials taken. Powder X-ray Diffraction was used to determine the Iron Nanoparticles’ average crystallite size. The structural morphology of iron nanoparticles, Polypyrrole, and polymer nanocomposite were identified by Scanning electron Microscopy. The SEM images gave the view of Iron nanoparticles, Polypyrrole was seated in the Polymer matrix. The specific capacitance for the newly synthesized Polymer Nanocomposite was found to be 58.88 F/g by Cyclic Voltammetric analysis. The electrochemical behavior of the random copolyester (BCPT), Iron nanoparticles, Polypyrrole, and polymer nanocomposite was carried out by Impedance analysis. This confirms the Polymer Nanocomposites were conducting nature with good ionic conductance of 6.89 × 10-5 S cm-1.
