Outline of Final Research Achievements

Friction between two solid materials with a nanoーscale space were studied by molecular dynamics simulation. Particularly, it was found how water within the nano-space affect the bulk friction between the two materials. In this study,
however, water flow within SWCNT was studied to investigate the basic friction phenomena between the SWCNTs and water.it was suggested that water cluster structures, such as hydrogen bond networks, in SWCNT and bulk play an important role on the bulk friction between the two solid materials.

Academic Significance and Societal Importance of the Research Achievements

通常の物質は、構成する物質結晶間に間隙を有していて、かつそこには水や空気などの吸着層が存在することが多い。これらの間隙物質(水やガス)はそのバルク物性に重大な影響を与えているいるものと考えられる。このような間隙を有する複合物質のバルク物性を明らかにしようとするもので、広く関心を曳き得る研究であると思われる。
