  • UV-CURABLE, WEAR RESISTANT AND ANTISTATIC COATING FILLED WITH CARBON NANOTUBES
    Publication number: 20120010316
    Abstract: A methodology is provided for making UV-curable, wear resistant and antistatic coating filled with carbon nanotubes (CNTs). The composition consists of a mixture of CNTs, an acrylate-based monomer, a urethane-acrylate oligomer and a photoinitiator. The present invention provides a coating of which the wear resistance and antistatic properties are dramatically improved in comparison with the polymer substrate. This coating is suitable for protecting a variety of polymer substrates from scratch and electrostatic accumulation.
