| Outline of Final Research Achievements |
It is well-known that polymer materials are proceeded to nanofibers, not only they become thinner, but also the molecular orientation of the fibers is enhanced. Previously, we had observed the structure of the nanofiber surface by atomic force microscopy (AFM), and found that 20 nm molecular domains were aligned along the long axis of the fiber. In addition, we found that the adsorption properties of biomolecules were enhanced with the change in the molecular structure of the fiber surface. In this study, we have verified that molecules are adsorbed linearly in the direction of the fiber's long axis and established a one-dimensional molecular arrangement technique for application.
