1. A method for quantifying at least one of a hydrophilic property and a hydrophobic property of a material, the method comprising:

  • exposing a material to a noble gas plasma, wherein the noble gas plasma emits at least one of Extreme Ultra Violet photons and Vacuum Ultra Violet photons having sufficient energy to cause photolysis of water molecules adsorbed by the material so as to release at least one of oxygen radicals, hydrogen radicals, and hydroxyl radicals;

    detecting an amount of at least one of released oxygen radicals, released hydrogen radicals, and released hydroxyl radicals; and

    quantifying at least one of a hydrophilic property and a hydrophobic property of the material based on the amount of at least one of the released oxygen radicals, the released hydrogen radicals, and the released hydroxyl radicals.
