Outline of Final Research Achievements

In this research project, we amalgamated our previous research accomplishments related to “nanofibers”, “photografting polymerizations”, and “functionalization of polymers”, in order to create new functional polymeric nanofibers. As a result, by introducing hydrophilicity, we fabricated new polyurethane nanofibers with excellent elasticity and high tensile property, which would be widely used in industry.　We have also succeeded in synthesizing antithrombogenic polyurethane nanofibers by introducing a highly biocompatible polymer, which would be utilized as a material for the medical applications.
