Gold Nanoparticles as Catalysts for Polymerization of Alkysilanes to Form Siloxane Nanowires

Reference Number: 03-11

Inventors: Ken Klabunde and Chris Sorensen et. al.


The technology consists of a new catalytic process that utilizes gold nanoparticles to form polysilozanes in wire, filament, or tubular form at the nanoscale level.


The technology utilizes a unique catalytic property of gold nanoparticles, which has the unexpected ability to polymerize alkysilanes in the presence of water to form siloxanes under mild conditions. Siloxane polymers are generally useful as silicone rubber, insulation, and other uses of flexible material that will remain flexible over a wide temperature range. An additional use for this technology would be the application to components in nanomechanical devices, such as springs, levers, and dampers. Another possible application would be to oxidize the siloxane nanowires to form silica (SiO2) nanowires, for use in light transmission.


This technology produces polymers in the shape of nanowires, filament, and tubes, using gold nanoparticles to enable the catalytic reactions. The reaction can be carried out at relatively low temperatures (120°C).
