AbstractCreating hybrid nanostructures of disparate nanoscale blocks is of interest of exploring new types of electronic devices and networks. Here, we demonstrate the novel coupling of gold nanoparticles of 3-4 nm diameters to sidewall of multiwalled carbon nanotubes (MWNTs) using the electroless plating technique. MWNTs were initially chemically modified with an H2SO4-HNO3 acid treatment, and subsequently activated with Pd-Sn catalytic nuclei via a one-step activation approach. When the activated MWNTs were immersed in a gold-containing electroless plating bath, gold deposition occurred at the catalytic sites. The deposited gold clusters then catalyze further gold deposition on the tube surface (autocatalytic process). Novel hybrid nanostructures with gold nanoparticles homogeneously distributed on MWNTs resulted. High-resolution transmission electron microscopy (HRTEM) and energy dispersive X-ray spectroscopy (EDS) were used to characterize the conjugation process.

AbstractComposite materials based on AMg2 aluminum alloy reinforced by additions of 0.05 wt % multiwalled carbon nanotubes (MWCNTs) or Al/MWCNT hybrid nanostructures have been obtained by powder metallurgy techniques. The evolution of MWCNTs and Al/MWCNT hybrid nanostructures at various stages of powder composite material formation has been studied by Raman spectroscopy. It is established that Al/MWCNT hybrid filler is subjected to lower damage and less favors the formation of Al_4C_3 phase during isothermal consolidation stage as compared to the case of nonmodified MWNTs.
