通过温和的等离子体法制备出碳纳米管负载纳米银粒子，并研究了其对大肠杆菌的抑制作用。首先用氧等离子体处理碳纳米管，再将银离子负载在碳纳米管表面上，接着用氢等离子体将负载的银离子还原成纳米银粒子。用TEM和XRD对制备出的银粒子进行表征，研究表明，平均粒径为5nm左右的银粒子负载在碳纳米管表面。对大肠杆菌的抑菌实验表明，Ag-CNTs浓度大于1μg/mL时，对大肠杆菌生长抑制效果明显。

A kind of mild Plasma has been used to synthesize Ag nanoparticles (AgNPs) supported on multi-walled carbon nanotubes (CNTs). First, the O2 plasma was utilized to treatment the surface of CNTs. Then the Ag+were decorated on the O2 plasma functionalized CNTs. At last, the pretreated composites were reduced into AgNPs supported on CNTs through mild H2 plasma.The Transmission electron microscope and X-ray diffraction indicated that the average size of AgNPs is about 5 nm and supported successfully on CNTs surfaces. Moreover, the antibacterial experiments demonstrated that the prepared Ag-CNTs have effective antibacterial activity against E. coli while concentration higher than 1μg/mL.
