Abstract:Highly dispersed Au and Au-Ag nanoparticles supported on carbon nanotubes are generated using an easy synthesis. MWCNT was opened and its derivative containing -COOH and -OH functional groups was obtained. Polycondensation of monohydrate citric acid in the presence of functionalized MWCNT in the melting state was lead to nanotube -graft- poly (citric acid) (CNT-g-PCA) nanocomposites. The CNT-g-PCA is soluble in water and capable to entrap water soluble chemical species and metal ions. The reaction between hybrid material and metal ions such as (Au, Ag) lead to the CNT-g-PCA containing encapsulated metallic nanoparticles in their polymeric shell. The structure and composition of the resulting new nanocomposites CNT-g-PCA /Au and CNT-g-PCA /Au-Ag were characterized with microscopy and spectroscopy methods.
