  • Conductive grease with enhanced thermal or electrical conductivity and reduced amount of carbon particle loading
    Patent number: 11053124
    Abstract: Disclosed herein is a conductive grease composition that includes a functionalized carbon nanomaterial and/or boron nanomaterial and a base oil. The nanomaterial and base oil forms hydrogen bond network in the disclosed composition. Because of the formed hydrogen bonds, the disclosed grease exhibits enhanced thermal or electrical conductivity. Also disclosed is a method to improve thermal or electrical conductivity of an existing grease composition.
    Type: Grant
