Abstract
An exemplary method of treating a material such as carbon or graphite to render at least some surfaces of the material hydrophilic includes coating at least a portion of the at least some surfaces with an oxygenated element and controlling a rate of a breakdown of the oxygenated element to leave a corresponding elemental oxide on the surfaces. In one example, the material is treated before being incorporated into an article comprising the material. Another example method includes treating an article comprising the material. Disclosed examples include precipitation or decomposition as the breakdown of the oxygenated element.
