Abstract

The purpose of this research is to develop advance conducting material blended with metal oxides that held both conducting and antimicrobial properties and due to this, applicable in many biomedical fields. The synthesis of nanoparticles of copper oxide (CuO) is performed by the chemical co-precipitation method and the synthesis of pure polyaniline (PANI) and PANI-CuO nanocomposites were performed by using in-situ chemical oxidative synthesis. The structural analysis was carried out by X-ray diffraction (XRD) studies, Fourier transform infrared spectroscopy (FTIR), and Ultraviolet – Visible (UV-Vis) absorption spectrometry. The peaks obtained in spectra validate the fabrication of desired materials. The average particle size of synthesized materials was calculated using the Debye Scherrer formula, which was found in the nanoscale range. The scanning electron microscope (SEM) images explored the morphology of CuO and PANI-CuO composite. The direct current (DC) conductivity measurement of samples was performed by the four-probe method for various temperatures. The values showed an increase of electrical conductivity in the composite as compared to PANI and supported the metallic nature of the composite. The antibacterial activity of composites was performed by disk diffusion method using Bacillus subtilis (Gram + ve bacteria) and Escherichia coli (Gram–ve bacteria) and the results are encouraging.
高性能导电纳米复合材料聚苯胺(PANI)-CuO具有增强抗菌活性的生物医学应用
这项研究的目的是开发先进的导电材料与金属氧化物混合,既具有导电性能又具有抗菌性能,因此可应用于许多生物医学领域。采用化学共沉淀法合成纳米氧化铜(CuO),采用原位化学氧化法合成纯聚苯胺(PANI)和PANI-CuO纳米复合材料。采用x射线衍射(XRD)、傅里叶变换红外光谱(FTIR)和紫外-可见(UV-Vis)吸收光谱法对其进行了结构分析。光谱中获得的峰验证了所需材料的制备。合成材料的平均粒径采用Debye Scherrer公式计算,该公式在纳米尺度范围内得到。扫描电镜(SEM)对CuO和PANI-CuO复合材料的形貌进行了研究。采用四探针法测定了样品在不同温度下的直流电导率。这些数值表明,与聚苯胺相比,复合材料的电导率有所提高,并支持了复合材料的金属性质。利用枯草芽孢杆菌(革兰氏杆菌)和大肠杆菌(革兰氏杆菌)的圆盘扩散法对复合材料进行了抑菌试验,结果令人鼓舞。
