  • Patent number: 7722786
    Abstract: A material for producing a conductive composition comprising polymer particles, conductive particles, and a liquid medium. The material is in a liquid/dispersion form until it is cured at which time it forms an electrically conductive composition. The composition contains larger sized polymer particles along with smaller metal conductive filler particles such as nanoparticle-sized filler particles. The larger polymer particles create excluded volume in the material matrix and reduce the percolation threshold of the conductive filler particles to provide a conductive material with a reduced volume fraction of electrically conductive filler. The electrical conductivity of the material is further increased after heat treatment which causes the conductive filler particles to sinter together to form a highly conductive network.

  • Publication number: 20080023108
    Abstract: A method for fluxing a solder comprises applying to the solder a fluxing agent in which the fluxing agent is a compound having (i) an aromatic ring, (ii) at least one —OH, —NHR (where R is hydrogen or lower alkyl), or —SH group (iii) an electron-withdrawing or electron-donating substituent on the aromatic ring, and (iv) no imino group.

  • Patent number: 6860956
    Abstract: Methods of creating patterns on substrates are presented, and articles of manufacture resulting therefrom. One method comprises applying a first surface energy modifier to an applicator to form a coating on the applicator; contacting the coating with a receiving member, the receiving member having a topography, the coating only contacting and remaining on at least some protrusions; exposing the first modified receiving member to a second surface energy modifier, thereby forming a second modified receiving member having surface modified recesses; applying a composition comprising a polymeric material to the second modified receiving member, the composition substantially conforming to the topography of the surface modified protrusions and the surface modified recesses; and contacting the composition-coated, surface modified protrusions with a substrate for a time and under conditions sufficient to transfer the polymeric material on protrusions to the substrate.
