Hybrid film for self-adhesion and shape-controlling

We report a hybrid film that is composed of “polymer nanosheet” with a hundreds-of-nanometer-thick film and “punched film” with hundreds-of-micrometer-thick film. Because of the thickness, the nanosheet is able to adhere to biological tissues without a glue, but is sometimes difficult to handling. Our hybrid film is established both adhesiveness of the nanosheet and shape-controlling ability of the punched film. In this paper, first, we fabricated the cylindrical-shaped hybrid film. Next, we achieved the hybrid film unfold into flat shape. Finally, we evaluated the adhesion force of the hybrid film and confirmed that the hybrid film can adhere to biological tissues.
