摘要

摘要在N2气氛中，通过改变聚吲哚和硝酸银的浓度，采用回流缩合法制备了聚吲哚基银氧化铜纳米复合材料(聚吲哚/ Ag-CuO)。采用傅里叶变换红外(FTIR)、x射线衍射(XRD)和扫描电子显微镜(SEM)对其进行了表征。扫描电镜图像显示了CuO纳米颗粒的迷人形状。红外光谱(FTIR)和x射线衍射(XRD)证实了纳米复合材料中存在银和CuO的官能团转变和结晶性质。研究了聚吲哚/ Ag-CuO纳米复合材料的抗菌活性，发现其对致病菌具有抗菌活性。图形抽象

Synthesis, Characterization, and Antibacterial Activity of Polyindole/Ag–Cuo Nanocomposites by Reflux Condensation Method

ABSTRACT Polyindole-based silver and copper oxide (polyindole/Ag–CuO) nanocomposites were synthesized using reflux condensation method by varying the concentrations of polyindole and silver nitrate with copper oxide in N2 atmosphere. They were characterized by Fourier transform infrared (FTIR), X-ray diffraction (XRD), and scanning electron microscope (SEM) techniques. The SEM images revealed fascinating shapes of CuO nanoparticles. The FTIR and XRD confirmed the functional group transformation and crystalline natures of silver and CuO existed in the nanocomposites. The polyindole/Ag–CuO nanocomposites were examined for antibacterial activity and found to exhibit the antibacterial activity against pathogenic bacteria. GRAPHICAL ABSTRACT
