Abstract

This study highlights the method of synthesis and characterization of a novel hybrid material consisting of zinc cobaltite (ZnCo₂O₄) and the conductive copolymer based on pyrrole and N-methyl pyrrole. The pure ZnCo₂O₄ is synthesized by sol-gel method, polypyrrole-ZnCo₂O₄, poly(N-methyl pyrrole)-ZnCo₂O₄ and poly(pyrrole-co-N-methyl pyrrole)-ZnCo₂O₄ are synthesized by chemical oxidative polymerization and characterized by different techniques. X-ray diffraction results revealed the existence of a cubic spinel structure of ZnCo₂O₄ in all samples. The synthesis efficiency of the polymer-ZnCo₂O₄ nanocomposite is confirmed by the Fourier transform infrared spectroscopy. The results of scanning electron microscopy show that the nanoparticles are mostly spherical in shape and the powders morphology structure varies from sample to sample. The energy dispersive X-ray analysis shows the formation of hybrid material with a substantial purity.

摘要

这项研究突出了由钴酸锌（ZnCo ₂ O ₄）和基于吡咯和N-甲基吡咯的导电共聚物组成的新型杂化材料的合成和表征方法。将纯的碳酸锌₂ ö ₄是通过溶胶-凝胶法，聚吡咯碳酸锌合成₂ ö ₄，聚（Ñ甲基吡咯）-ZnCo ₂ ö ₄和聚（吡咯共- ñ -ZnCo甲基吡咯）₂ ö ₄通过化学氧化聚合合成并通过不同技术表征。X射线衍射结果表明在所有样品中均存在立方尖晶石结构的ZnCo ₂ O ₄。聚合物-ZnCo ₂ O ₄纳米复合材料的合成效率通过傅立叶变换红外光谱法得到证实。扫描电子显微镜的结果表明，纳米颗粒的形状大多为球形，并且粉末的形态结构随样品的不同而不同。能量色散X射线分析表明形成了纯度很高的杂化材料。
