Abstract
A method to bond carbon nanotubes to a surface. The mechanism of this bonding is studied, and shows that intercalation of alkali ions is possibly the central mechanism. Bonding pull-off forces of 4-5 N/cm2 were measured. This bonding also provides improved interfacial properties for other phenomenon, including improved thermal conductivity.
Claims16
A method for preparing carbon nanoparticles on a substrate, comprising:
- providing a substrate and an object having a surface;
- growing a plurality of vertically-oriented carbon nanotubes from the substrate, each carbon nanotube having a free end;
- intercalating alkali ions into the carbon nanotubes;
- contacting the free ends of the nanotubes with the surface of the object;
- applying a compressive pressure to the nanotubes and substrate during said contacting;
- and
- migrating the alkali ions from the nanotubes to the surface of the object after said contacting.
