1. An inkjet printhead comprising a front face having a polymer coating, the polymer coating comprising an oleophobic grafted polymer comprising:
a crosslinked fluoroelastomer; and a perfluorinated polyether grafted to the crosslinked fluoroelastomer;
wherein the crosslinked fluoroelastomer is crosslinked with an aminofunctionalized silane, the aminofunctionalized silane comprising an aminoalkylsilane-modified polysiloxane.
