  • Publication number: 20030068486
    Abstract: Nanocomposite hardcoats having smudge and abrasion resistant properties are disclosed. Latent reactive nanoparticles are contained within a binder phase to form a nanocomposite. When deprotected and treated with a reactive fluorochemical, nanoparticles present at the surface of the nanocomposite become permanently modified and impart smudge resistance. The nanocomposite hardcoats may optionally be supported on a primary substrate.

  • Publication number: 20020119304
    Abstract: The present invention relates to metal oxide particles capable of being highly dispersed in organic materials to form transparent colloids and ceramers. The metal oxide particles of the present invention have surfaces attached to a dispersing aid and a degree of crystallinity of greater than 55 percent. The crystallite diameter of the metal oxide particles is greater than about 4 nanometers and less than about 20 nanometers. The present invention also relates to the colloids and ceramers prepared using these metal oxide particles and the methods associated with the preparation of the particles, colloids, and ceramers.
