Patent ID: 7101616

Claim:
A method for preparing a smudge and abrasion resistant article comprising the steps of: a) contacting a plurality of nanoparticles with a latent coupling agent to form latent reactive nanoparticles; b) intimately mixing the latent reactive nanoparticles with a binder precursor; c) curing the binder precursor to form a nanocomposite having an exposed first surface comprising latent reactive nanoparticles; d) deprotecting a plurality of latent reactive nanoparticles to form reactive nanoparticles at the first surface of the nanocomposite; and e) contacting a reactive fluorochemical with the first surface of the nanocomposite such that fluorinated organic groups are covalently bonded to a plurality of the reactive nanoparticles present at the first surface of the nanocomposite.
