US Patent 7731928 - Silanized CNTs

Qimonda AG is a semiconductor memory company which, while recently undergoing bankruptcy issues, has developed several innovative solutions for semiconductor device development. For example, this latest patent teaches a process to form a dielectric coating on nanotubes useful to the fabrication of CNT sensors and transistors. Claim 1 reads:

1. A process for silanizing carbon nanotubes, wherein the carbon nanotubes are oxidized and subsequently exposed to a saturated gas phase comprising one or more organosilane derivatives which form covalent bonds to the carbon nanotubes with siloxane formation.
