Preparation of Silver Nanoparticles in Cellulose Acetate Polymer and the Reaction Chemistry of Silver Complexes in the Polymer

In this study, infrared spectroscopy is quite helpful in following gas phase reaction process and analyzing gas products on the basis of well-known infrared spectral data. These Ag-containing films are light brown colored and transparent. They are thermally and mechanically stable up to 200 .deg. C. Infrared spectra in 4000-250 cm^-1 region were recorded on Jasco FT/IR 5300, and Nicolet MX-5 spectrometer. UV/Vis spectra for elution tests were recorded on a Jasco V-550 spectrometer. Thermal properties of the films were examined by Setaram LABSYS analyzer and transmission electron microscopy (TEM) were performed on a JEM-200CX microscope to observe silver metal particles in CA. Various gas products were analyzed by Donam G/C, Autospec EBE GC/Mass spectrometer, and gas phase FT-IR spectroscopy. For high-pressure gas phase reactions, Parr reactors were used with automatic temperature control systems. Polymer/inorganic composites have been an active research subject of great practical importance in last decades because of their interesting physicochemical properties. Also, these materials received attention in the search of practical methods for the synthesis of various inorganic nanoparticles, which were reported to have more controls over cluster formation, their size and shape, and their size distribution. We reported a series of articles about the preparation of Ru, Rh, Pd, Fe, and Cu metal nanoparticles in various polymers such as cellulose acetate, polycarbonate, polysulfone, and silicon rubber in addition to their reaction chemistry; the transition metal nanoparticles in those polymer matrices showed quite interesting chemical and/or catalytic reactivity toward various small gas molecules under relatively mild conditions, which are quite different from those of corresponding free transition metal complexes or from those in inorganic oxide-supported systems
