  • Publication number: 20180029351
    Abstract: An apparatus and method of manufacturing a fluorosilicone composite for a variable data lithography imaging member surface layer. Examples of the fluorosilicone composite include a first part and a second part, the first part having fluorosilicone, carbon black, silica and butyl acetate, the second part having a platinum catalyst, a crosslinker, butyl acetate and an inhibitor. The first part may also include a dispersant (e.g., a polyoxyalkylene amine derivative) that removes a need for shaking the dispersion by paint shaker and instead allows a more manufacture friendly roll ball milling process. The dispersant will also help in stabilizing the fluorosilicone composite for scaled up production.

  • Patent number: 9394421
    Abstract: A method for forming a dispersion includes mixing graphene particles, a fluorosilane coupling agent and a first solvent to produce a first dispersion wherein the graphene particles are from about 0.1 to about 0.8 weight percent of the first dispersion. The method includes concentrating the first dispersion by removing the first solvent to produce a second dispersion wherein the graphene particles are from about 2.0 to about 10.0 weight percent of the concentrated dispersion. The concentrated dispersion is mixed with a fluoropolymer dispersion including a second solvent, a surfactant, and fluoropolymer particles wherein the fluoropolymer dispersion has a solids content of about 30 weight percent to about 50 weight percent to form a second dispersion. A polymer binder in a third solvent is mixed with the second dispersion to form the coating dispersion.
