Abstract
A marking system surface material includes a fluoroelastomer including grafted fluorinated polymers. The fluoroelastomer is a perfluoropolyether-grafted fluoroelastomer formed using an alkoxy-terminated fluorosilicone component, and exhibiting high contact angle and low sliding angle.
Claims14
A fluoropolymer composition, comprising:
- a fluoroelastomer component;
- and
- a perfluoropolyether component, the fluoroelastomer component being grafted to the perfluoropolyether component with an amino-functionalized alkoxy-terminated fluorosilicone component.
A method of forming a fluoroelastomer comprising grafted fluorinated polymers, the method comprising:
- combining a first solution comprising a fluoroelastomer component and a second solution comprising an amino-functionalized fluorosilicone crosslinker component including a perfluoropolyether component, the fluoroelastomer component being grafted to the perfluoropolyether component with an amino-functionalized alkoxy-terminated fluorosilicone component.
An ink-based digital printing system, comprising:
- an imaging member having a reimageable surface layer, the surface layer comprising a fluoroelastomer component and a perfluoropolyether component, the fluoroelastomer component being grafted to the perfluoropolyether component with an amino-funetionalized alkoxy-terminated fluorosilicone component;
- a dampening fluid metering system, the dampening fluid metering system being configured to apply dampening fluid onto the reimageable surface;
- a dampening fluid patterning system, the dampening fluid patterning system being configured to form a pattern in the applied dampening fluid;
- and
- an inking system, the inking system being configured to apply ink to the imaging member surface, the surface having the patterned dampening fluid disposed thereon.
