  • Diazonium functionalized nanoparticles and methods for binding nanoparticles to metallic surfaces
    Patent number: 8236422
    Abstract: In one embodiment, a functionalized particle includes a n inorganic particle with diazonium functional group attached. In some embodiments, the largest dimension of the inorganic particle ranges between about 10 nm and 1000 ?m. In another embodiment, a substrate with a hydrophobic surface includes a substrate, and a first plurality of inorganic particles with at least one diazonium functional group attached to the substrate. The largest dimension of the first plurality of inorganic particles ranges between about 10 nm and 1000 ?m. One embodiment includes a second plurality of particles with at least one phenol functional group attached to the inorganic particle. In a further embodiment, a fluorinated functional group is attached to the second plurality of particles. In some embodiments, the material has a hydrophobic surface with a water contact angle greater than about 150°.
