| Outline of Final Research Achievements |
The purpose of this study was to establish a new method for new polymer composites, in which polymer nanofibers were well-dispersed. The method was also utilized to make a new functional composite. In particular, by ejecting polymer nanofibers into liquid polymer or polymer solution using the electrospinning method, well-dispersed polymeric nanofiber composites have been produced. An organic solvent, in which polymer nanofibers could be well dispersed, was carefully selected from twelve organic solvents. New functional composites were then made by this new method. A biodegradable poly(ε-caprolactone) (PCL) was used as a matrix material, and poly(vinyl alcohol) (PVA) with high mechanical properties and high heat resistance was selected as a nanofiber-reinforcement material. The resulting polymer-fiber composites possessed biodegradability, high Young’s modulus, and high heat resistance.
