  • Patent number: 8105660
    Abstract: A method of forming a diamond-like carbon coating by plasma enhanced chemical vapor deposition on an internal surface of a hollow component having an inner surface. A reduced atmospheric pressure is created within a pipe or other hollow component to be treated. A diamondoid precursor gas is introduced to the interior of the component. A bias voltage is established between a first electrode and one or more second electrodes. The first electrode is or is attached to the component. The second electrode is externally offset from an opening of the component, by a hollow insulator. A plasma region is established adjacent an inner surface of the component and extends through the hollow insulator. The precursor gas comprises at least one diamondoid. The pressure and bias voltage are selected such as to cause the deposition of diamond-like carbon on the inner surface.

  • Patent number: 8013078
    Abstract: This invention is related to heteroatom containing diamondoids (i.e., “heterodiamondoids”) which are compounds having a diamondoid nucleus in which one or more of the diamondoid nucleus carbons has been substitutionally replaced with a noncarbon atom. These heteroatom substituents impart desirable properties to the diamondoid. In addition, the heterodiamondoids are functionalized affording compounds carrying one or more functional groups covalently pendant therefrom. This invention is further related to polymerizable functionalized heterodiamondoids. In a preferred aspect of this invention the diamondoid nuclei are triamantane and higher diamondoid nuclei. In another preferred aspect, the heteroatoms are selected to give rise to diamondoid materials which can serve as n- and p-type materials in electronic devices can serve as optically active materials.

  • Publication number: 20100221453
    Abstract: Diamonds are used to nucleate diamond and diamond-like carbon films in a chemical vapor deposition process using bias enhancement. A negative bias is applied to the substrate, such that a cationic form of the diamond is accelerated toward the substrate during the nucleation phase of the deposition. In this manner, the diamondoid may be embedded or partially embedded in the substrate and/or growing film, increasing the adhesion of the film to the substrate. According to the present embodiments, it is not necessary to mechanically pre-seed the substrate for nucleation purposes.

  • Publication number: 20090176035
    Abstract: The invention relates to a method for forming high sp3 content amorphous carbon coatings deposited by plasma enhanced chemical vapor deposition on internal surfaces and employing the “hollow-cathode” technique. This method allows adjustment of tribological properties, such as hardness, Young's modulus, wear resistance and coefficient of friction as well as optical properties, such as refractive index. In addition the resulting coatings are uniform and have high corrosion resistance. By controlling pressure, type of diamondoid precursor and bias voltage, the new method prevents the diamondoid precursor from fully breaking upon impact with the substrate. The diamondoid retains sp3 bonds which yields a high sp3 content film at higher pressure. This enables a faster deposition rate than would be possible without the use of a diamondoid precursor.

  • Publication number: 20090075203
    Abstract: Novel positive-working photoresist compositions are disclosed. The monomers of the base resin of the resist contain diamondoid-containing pendant groups higher than adamantane in the polymantane series; for example, diamantane, triamantane, tetramantane, pentamantane, hexamantane, etc. The diamondoid-containing pendant group may have hydrophilic-enhancing substituents such as a hydroxyl group, and may contain a lactone group. Advantages of the present compositions include enhanced resolution, sensitivity, and adhesion to the substrate.
