Abstract


Nanomaterials play a pivotal role in the development of nano science and technology. Though the methods of preparation for nanomaterials are increasing remarkably these years, most of them require special equipments or long time. In this way, it is critical to develop a convenient and fast method to synthesize nanoparticles.In this paper, a simple and effective method for the rapid synthesis of silver nanoparticles was developed at room temperature. The nanostructures were characterized by TEM, UV-vis in-situ, fluorescence and so on. Moreover, as antibacterial agents, we applied the silver nanoparticles to different fabric and tested their antibacterial properties. The main work is as fellows:Ag nanoparticles were synthesized rapidly in1atm hydrogen atmosphere at room temperature, and the growth mechanism of nano-silver was explained briefly. Besides, silver-containing bimetallic nanoparticles were synthesized on the basis of this method;Used the above method to finish fabric in situ rapidly, and tested the antibacterial properties of the fabric. The results showed that not only we can quickly prepare the nano silver-containing fabric, but also the fabric own excellent antibacterial properties. The inhibition rates of Escherichia Coli and Staphylococcus Aureus are both above99%even after washing20times.
