| Abstract |
本研究では, 研究代表者が基盤研究Aで実験的に実現しようとしているポリマナノ複合材料の研究をおし進め, 新規物性を有する複合材料を効率的に創り出すことを目的としている。特に本研究では, 材料どうしの機械的な複合と化学的な相溶という2種類のスケールの違う複合化に着目し, その2点を融合し, 機械的複合化で生じた界面エラー(低接着, ボイド)等のボトムアップ対策を研究してきた。具体的には, 化学的な相溶性を考慮し, 母材に近いポリマ分散材を複合化させる自己強化型複合材料に着目することで, 界面空隙のほとんどないポリ乳酸ベースのポリマ複合材料を作製できるようになった。
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.
