    Abstract: This disclosure is directed to a plate design for use in variable data digital lithographic image forming devices. The disclosed plate design incorporates surface passivated carbon black filler material particles in a fluorosilicone polymer. The disclosed functionalized carbon black material compositions include hydrophobic carbon black particles surface passivated via the use of an A/B-block copolymer where the A/B block contains a pentafluorostyrene-maleimide alternating polymer and the B block contains pure pentafluorostyrene. The A/B portion allows for the polymer to adsorb onto the carbon black while the b-block acts as the stabilizer in fluorinated systems. Fine dispersions result from the addition of poly (pentafluorostyrene/Maleimide-b-pentafluorostyrene) or P(PFS/MI-b-PFS) passivated carbon black to fluorinated polymers, enhancing the physical and mechanical properties. The disclosed surface passivated carbon black particles are particularly usable for improving operational characteristics of fluorosilocone-based reimageable surface layers of imaging members employed in the variable data digital lithographic image forming devices.
