Structures of interfaces between materials and lubricants are analyzed by neutron reflectometry and discussed in the series of studies. In this paper, three kinds of DLC films having different surface energies (normal DLC, hydrophilic DLC and hydrophobic DLC) were prepared as base materials, and water and 2-propanol were selected as lubricants. The instrument we used was a neutron reflectometer 'MINE' in Japan Atomic Energy Agency (JAEA). The DLC films were soaked into the lubricants in a specially-designed sample holder, and the neutron reflectivity profiles from the interface between DLC films and lubricants were directly obtained. Through an analytical fitting approach with Parratt's theory to the obtained profiles, authors presented the strict structure of the interface.
