  • Publication number: 20090320911
    Abstract: A method and system for improving the electrical conductivity of the nodes of a nanotube net and related materials. A method for adding material to the nodes of a nanotube net that provides more pathways and connections to guarantee good electrical conductance between one electrode and another and speeds the transmission of charge carriers by providing alternative pathways. These improvements may include an enhanced overall thermal conductivity of the CNT net and enhanced mechanical performance of the CNT net. The present disclosure improves, either independently or jointly, electrical, thermal, or mechanical properties of CNT nets. Further, optical transmission does not worsen significantly.

  • Publication number: 20070131915
    Abstract: A method of making a dispersion of reduced graphite oxide nanoplatelets involves providing a dispersion of graphite oxide nanoplatelets and reducing the graphite oxide nanoplatelets in the dispersion in the presence of a reducing agent and a polymer. The reduced graphite oxide nanoplatelets are reduced to an extent to provide a higher C/O ratio than graphite oxide. A stable dispersion having polymer-treated reduced graphite oxide nanoplatelets dispersed in a dispersing medium, such as water or organic liquid is provided. The polymer-treated, reduced graphite oxide nanoplatelets can be distributed in a polymer matrix to provide a composite material.
