The photoreaction of diamond-like carbon (DLC) films in the presence of hydrogen peroxide leads to the covalent modification of their surface through the introduction of oxygen-containing functional groups, as confirmed by X-ray photoelectron, infrared and Raman spectroscopies. The DLC films modified with oxygen moieties showed high hydrophilicity, evaluated by their contact angle with water, compared with a pristine DLC film, and good tribological properties from the initial stage in water. The chemical structure of oxygen-terminated DLC films was also controlled by reduction of the oxygen moieties using hydride agents.
