Derived Properties

AbstractHybrid materials, which consist of organic-inorganic materials, are of profound interest owing to their unexpected synergistically derived properties. Aluminum oxide (Al2O3) nanoparticles/polymer composites have been produced using a one-system polymer synthesis. The linear polymer, poly(methyl methacrylate) (PMMA,MW=15,000 g/mol) is applied for the stabilization of Al2O3nanoparticles. Fourier transfer infrared analysis data and scanning electron microscopy image reveal that the core shell structure of the Al2O3/PMMA nanocomposite has been synthesized. The ratio of concentration of the capping polymer material to the concentration of the Al2O3precursor could control the size of Al2O3nanoparticles. With specific concentration of the reductant, the core-shell nanostructure could be fluctuated in order.

ABSTRACTSolid sol of silver in poly(methyl methacrylate), Ag/PMMA, was prepared by bulk polymerization of methyl methacrylate solution of silver (I) triflluoroacetate (AgTfa) and followed by postheating. The formation of the metallic Ag nanocluster was characterized by visible spectroscopy, and effects of the concentrations of AIBN and AgTfa and the heat-treatment duration on the formation of Ag cluster were investigated. Furthermore, based on the kinetic study of MMA in the presence of AgTfa, possible mechanism for the reduction and agglomeration of silver is proposed.
