Ag/PMMA nanocomposite through reduction of silver ions by butylated hydroxytoluene

Silver nanoparticles (Ag NPs) were efficiently generated by insitu reduction of silver ions via butylated hydroxytoluene (BHT) in poly(methyl methacrylate). Optical properties of the Ag/PMMA nanocomposite were investigated. The role of temperature on the reduction activity of BHT and the yield of produced Ag NPs were also indicated by the UV-vis spectroscopy. Further characterizations of the Ag/PMMA by TEM, SEM, XRD, and FTIR indicated that Ag NPs with a mean diameter of about 30 nm were dispersed in PMMA matrix with a relatively uniform distribution. A provisional reduction mechanism was proposed for the formation of the Ag NPs.
