Synthesis and X-ray photoelectron spectroscopy studies of poly(vinyl pyrrolidone) capped gold nanoparticles in a hybrid composite

Mishra A., Tripathy P., Ram S., Fecht H-J., Indian Institute of Technology, IN

Gold nanoparticles are synthesized by direct reduction of an aqueous solution of the metal salt with a surface regulating polymer N-polyvinyl pyrrolidone (PVP), which bind on the gold surface, insulate the particles from Au3+ and [...]

Mechanical properties under nanoindents in gold nanoparticles reinforced poly(vinyl alcohol) nanocomposite films

Tripathy P., Mishra A., Ram S., Fecht H-J., Indian Institute of Technology, IN

Free standing films of gold nanoparticles reinforced poly(vinyl alcohol) (PVA) nanocomposite are synthesized by a novel chemical method with selective Au-contents varied from 0.1 to 5.0 wt%. The color change in the Au-PVA nanocomposite films [...]
