Patent ID: 8475704

Claim:
A method for making an ink jet printhead nozzle plate comprising: providing a plate substrate; and coaxially electrospinning a core polymer and a shell polymer to form a coaxially electrospun layer on the plate substrate, wherein the coaxially electrospun layer provides a low adhesion, oleophobic textile surface exhibiting a low sliding angle with at least one of the jetted drops of ultra-violet gel ink and jetted drops of solid ink, and wherein the low sliding angle is from less than about 1° to less than about 30°, and wherein the shell polymer comprises a material including at least one selected from the group consisting of: a) a polymer or an oligomer containing an isocyanate functional group, wherein the isocyanate functional group is selected from the group consisting of diphenylmethane diisocyanate, toluene diisocyanate, hexamethylene diisocyanate, isophorone diisocyanate, a polymer or oligomer containing isocyanate (—NCO) functional groups, and a mixture thereof; b) a polymer or oligomer comprising an isocyanate functional group; a polymer or oligomer comprising a hydroxyl functional group; and a hydroxyl functionalized polymer or oligomer comprising at least one polysiloxine unit; c) a polymer or oligomer comprising an isocyanate functional group; a polymer or oligomer comprising a hydroxyl functional group; and a hydroxyl functionalized fluoro-crosslinking material; d) a polymer or oligomer comprising an isocyanate functional group; a polymer or oligomer comprising a hydroxyl functional group; a hydroxyl functionalized polymer or oligomer comprising at least one polysiloxane unit; and a hydroxyl functionalized fluoro-crosslinking material; and e) an isocyanate; a polylol; a hydroxyl functionalized polysiloxane; and a hydroxyl functionalized fluoro-crosslinking material.
