The carbon dot initiated polypyrrole (PPY) and CuO composite were synthesized into PPY@CuO using a simple one-step sonochemical approach. The synthesized PPY and the PPY@CuO were characterized using Fourier-transform infrared spectroscopy, thermogravimetric analysis, X-ray diffraction, 13C-solid-state nuclear magnetic resonance (NMR) spectroscopy, UV–visible spectroscopy, and scanning electron microscopy. A strong interaction was demonstrated between the PPY chains and CuO. This interaction led to changes in the backbone chain of the PPY@CuO composite when compared to the carbon dot initiated PPY. The antibacterial activity against Escherichia coli and Staphylococcus aureus of the carbon dot initiated synthesis of PPY and the sonochemically prepared PPY@CuO composite materials was revealed. The results indicate the biocidal efficacy of PPY@CuO on both Gram-positive and Gram-negative bacteria. The PPY@CuO composite exhibited an enhanced antibacterial performance in comparison with the carbon dot initiated PPY and CuO. This is a first report on the sonochemical synthesis of a polymer composite composed of PPY and CuO, demonstrating the efficacy of its antibacterial action at a concentration of 1 mg/mL of the composite involving 0.234 mg/mL of CuO.

碳点引发的具有增强抗菌活性的聚吡咯和Polypyrrole @ CuO微米/纳米颗粒的合成
碳点引发的聚吡咯（PPY）和CuO复合材料通过简单的一步声化学方法合成为PPY @ CuO。使用傅立叶变换红外光谱，热重分析，X射线衍射，13 C固态核磁共振（NMR）光谱，UV可见光谱和扫描电子显微镜对合成的PPY和PPY @ CuO进行了表征。在PPY链和CuO之间表现出强烈的相互作用。与碳点引发的PPY相比，这种相互作用导致PPY @ CuO复合材料的主链发生变化。对大肠杆菌和金黄色葡萄球菌的抗菌活性揭示了碳点引发的PPY的合成和声化学制备的PPY @ CuO复合材料。结果表明，PPY @ CuO对革兰氏阳性菌和革兰氏阴性菌均具有杀菌作用。与碳点引发的PPY和CuO相比，PPY @ CuO复合材料表现出增强的抗菌性能。这是关于声化学合成由PPY和CuO组成的聚合物复合材料的第一份报告，证明了在浓度为1 mg / mL的复合材料（包括0.234 mg / mL的CuO）下，其抗菌作用的功效。
