载银多壁碳纳米管抗菌剂结构与性能的研究

Structure of multi-walled carbon nanotubes antibacterial agent and study on its properties

以多壁碳纳米管(MWNTs)为载体,通过化学吸附的方法制备载银多壁碳纳米管(Ag/MWNTs)抗菌剂。用SEM、TEM、FT-IR、XRD对其表观形貌、结构进行了表征。结果表明,银离子(Ag+)被吸附到MWNTs的表面,通过抑菌环实验表明,Ag/MWNTs对大肠杆菌和金黄色葡萄球菌都有很好的抗菌效果。

Muti-walled carbon nanotubes loaded silver（Ag/MWNTs） antibacterial agent was produced with the carrier of Muti-walled carbon nanotubes（MWNTs） by the chemical absorbing approach.And it employed the TEM,SEM,FT-IR,XRD to characterize the apperance and stucture.The result demonstrated that silver irons（Ag＋） were absorbed on the surface of MWNTs and also there was an excellent effect for E.coli and S.aureus through the antibaterial experiments.
