| Outline of Final Research Achievements |
The film structure of ultra-thin perfluoropolyether lubricant film adsorbed on solid surfaces and the micro/nano textured surfaces were studied in order to achieve the molecularly ultra-thin lubricated surface with the low adhesion and high durability. As the results, (1) the coverage of lubricant film less than the monolayer thickness much affects to the adhesion and friction forces, and (2) the flexibility of lubricant molecules on rigid surfaces with lubricant film thicker than the monolayer affects to the friction coefficient. Furthermore, the photoelectron assisted ultraviolet irradiation process was developed to improve the coverage and chemical bonded ratio of lubricant film, and it was confirmed that the hole pattern texture showed much higher oil repellency.
