Title:
SILICON NANOPARTICLE NANOTUBES AND METHOD FOR MAKING THE SAME
Document Type and Number:
WIPO Patent Application WO2006073469
Kind Code:
A3
Abstract:
A relatively thick electrode (10) is positioned opposite the surface of a substrate/second electrode (12). The electrode and the substrate surface are both contacted by a solution (16) including silicon nanoparticles. The substrate surface is completely immersed in the solution (16) in a manner such that there is not an air/solution interface and there is no meniscus at the substrate surface. Application of electrical potential between the electrode (10) and the substrate (12) creates a film of silicon nanoparticles on the substrate. Drying of the film induces the film to roll up and form a silicon nanoparticle nanotube material. A film may be subdivided into an array of identical portions, and the identical portions will roll into identical tubes having same length and diameter. A silicon nanoparticle nanotube material of the invention includes nanotubes formed of silicon nanoparticles.
