摘要：

Nylon 6 doped with Ag nanoparticles (nylon 6/Ag) was prepared by immersion of nylon 6 in aqueous AgNO3 solution followed by reductive treatment by heating under H-2 gas or immersing in an aqueous NaBH4 solution. As a result of either reductions, Ag nanoparticles below 10 nm in diameter were successfully dispersed within the nylon 6 matrix. The Ag content and the dispersion state of the Ag nanoparticles can be varied by the concentration of the AgNO3 solutions and the reduction methods, respectively. From the results of the absorbed Ag+ content in nylon 6 via immersion in AgNO3 solution, nylon 6 was found to have some affinity for silver ion. Nylon 6 doped with Ag2S nanoparticles (nylon 6/Ag2S) was also prepared by immersion in AgNO3 aqueous solution and the following immersion of Na2S aqueous solution. Ag2S particles having several nanometers in diameter were dispersed in nylon 6. The nylon 6/Ag2S film showed strong photoluminescence in the near infrared region.
