US 8,941,094 B2 · Methods for adjusting the conductivity range of a nanotube fabric layer

Abstract

Methods for adjusting and/or limiting the conductivity range of a nanotube fabric layer are disclosed. In some aspects, the conductivity of a nanotube fabric layer is adjusted by functionalizing the nanotube elements within the fabric layer via wet chemistry techniques. In some aspects, the conductivity of a nanotube fabric layer is adjusted by functionalizing the nanotube elements within the fabric layer via plasma treatment. In some aspects, the conductivity of a nanotube fabric layer is adjusted by functionalizing the nanotube elements within the fabric layer via CVD treatment. In some aspects, the conductivity of a nanotube fabric layer is adjusted by functionalizing the nanotube elements within the fabric layer via an inert ion gas implant.
