| Outline of Final Research Achievements |
The purpose of this research project is to establish an effective method to fabricate ideal polymeric nanocomposite materials. In this research, we have particularly tried to solve possible interfacial errors of the nanocomposites, such as low adhesion and micro-voids observed between the matrix and the one-dimensional reinforcement nanofibers. As a result, by carefully considering the compatibility between the matrix and the nanofibers, we could fabricate a polylactide(PLA)-based self-reinforced nanocomposite, where stereo-complex PLA nanofibers were successfully compounded into the PLA matrix. It was found that the thermo-mechanical properties of the new PLA composites have been significantly enhanced. It was therefore concluded that we could experimentally realize a polymeric nanocomposite with almost no interfacial gap between the matrix and the nanofibers. We will further conduct our research on such new composites especially consisting of different types of polymers.
