  • Polysiloxane Modified Titanium Dioxide
    Publication number: 20130149536
    Abstract: A particle of titanium dioxide treated with a polysiloxane is disclosed. One or more silicon atoms of the polysiloxane is substituted with an alkylene group terminating with a silyl group containing three substituents selected from the group consisting of hydroxy, halo, alkoxy, acetoxy, and mixtures thereof. These treated particles are blended with organic polymers to form a polyethylene polymer matrix having dispersed therein at least 55 wt % polysiloxane modified titanium dioxide particles.
    Type: Application

  • Method of providing a vertical interconnect between thin film microelectronic devices
    Patent number: 6400024
    Abstract: A simple and reliable method of providing a vertical interconnect between thin-film microelectronic devices is provided. In said method, a tool tip is used to make a notch in a vertical interconnect area of two organic electrically conducting areas separated from each other by an organic electrically insulating area. The method is used in the manufacture of integrated circuits consisting substantially of organic materials.
