| Outline of Final Research Achievements |
In this study, a new method of manufacturing cylindrical structure in small scale was proposed. When a thin film floated on water is pulled up, it automatically deforms due to capillarity and eventually wraps liquid drop to form a cylindrical structure. The proposed method was confirmed by polymer films and rubber sheets in various dimensions. In addition, an analytical model was established to predict size of the cylindrical structure and maximum thickness of films for formation. Molecular dynamics simulation was also conducted to show the manufacturing a graphene roll from graphene sheet.
