Patent ID: 7919417

Claim:
A sheet of material having a hydrophobic and oleophobic polymer coating on at least one surface thereof, comprising: a sheet of material having a first surface and a second surface; an aqueous hydrophobic and oleophobic coating composition having a critical micelle concentration, the aqueous hydrophobic and oleophobic coating composition containing a surfactant and a hydrophobic and oleophobic polymer consisting of one monomer coating at least one of the first surface and second surface of the sheet of material, the surfactant having a hydrophilic head group, a hydrophobic tail group and a concentration less than the critical micelle concentration; and an initiator introduced into the aqueous hydrophobic and oleophobic coating composition on the at least one of the first and second surfaces of the sheet of material to initiate the polymerization of the hydrophobic and oleophobic coating composition disposed on the at least one of the first and second surfaces of the sheet of material so that a hydrophobic and oleophobic polymer coating forms on at least one surface of the sheet of material.
