  • Plasma treated semiconductor dichalcogenide materials and devices therefrom
    Patent number: 9472396
    Abstract: A plasma-based processing method includes depositing a transition metal dichalcogenide (TMDC) material onto a substrate. The TMDC material is plasma treated in an oxygen containing ambient to oxidize the TMDC material to form oxidized dielectric TMDC material. The oxidized dielectric TMDC material has a higher electrical resistivity as compared an electrical resistivity of the TMDC material before the plasma treating, typically >103 times greater.
    Type: Grant
    Filed: April 15, 2015
    Date of Patent: October 18, 2016
    Assignee: University of Central Florida Research Foundation, Inc.
    Inventors: Saiful Khondaker, Muhammad Islam, Laurene Tetard

  • Polymer composites having highly dispersed carbon nanotubes
    Patent number: 8709292
    Abstract: A carbon nanotube-polymer composite includes a polymer continuous phase having at least a first polymer, and a plurality of carbon nanotubes dispersed in the polymer continuous phase. The carbon nanotubes are non-functionalized nanotubes. The carbon nanotubes are between 0.05 and 40 weight % of the composite. At least 98% of the carbon nanotubes are not involved in nanotube bundles.

  • Polymer composites having highly dispersed carbon nanotubes and methods for forming same
    Patent number: 7951850
    Abstract: A method of forming carbon nanotube-polymer composites includes the steps of forming a mixture solution including a plurality of carbon nanotubes dispersed in a co-solvent. The co-solvent includes an organic solvent and a second solvent being a short chain fluorinated carboxylic acid having a boiling point below 150° C. which is less oxidizing than nitric acid, and is soluble in both the organic solvent and water. The first polymer is mixed with the mixture solution to form a polymer including mixture. The co-solvent is removed from the polymer mixture to form a dispersed nanotube-polymer composite. The second solvent can be trifluoroacetic acid.
