概要: 金沢大学理工研究域生命理工学系<br />As an alternative to petroleum-based compatibilizing agents, we developed lignin derivatives for co mpatibilizing agents of carbon fiber-reinforced plastics that have thermoplasticity. In this study, alkyl chains were introduced into alkali lignin at various ratios to optimize the compatibility of the lignin derivatives with both polypropylene and carbon fiber. The interfacial shear strength between the two materials was improved from 8.2 to 17.2 MPa by mixing with the optimized lignin derivative. The value is comparable to that achieved with a typical petroleum-based compatibilizing agent (18.3 MPa).<br />Embargo Period 6 months<br />This paper has supplementary information. 続きを見る

概要: 金沢大学理工研究域自然システム学系<br />高分子化合物の配列制御を人工的に行うことにより、新しい高分子材料の可能性が引き出されると期待されている。本研究では多成分連結反応を活用することで、高分子化合物上での生物由来資源の配列制御に挑んだ 。その結果、アミノ酸から誘導したビスカルボン酸、ビスイソシアニド、アルデヒド(さらには、Ugi反応の場合にはアミン)モノマー間の反応を行い、多成分連結重合が進行することが判明した。上記と並行し、生物由来モノマーの活用として、リグニン誘導体の活用も併せて行った。その結果、リグニン誘導物質が多成分連結反応の反応場として有用である事が判明し、配列制御に繋がる高分子反応が可能であった。<br />In this work, the multi-component reactions (MCRs) were utilized for polymer synthesis in order to synthesize sequence-controlled polymers. For this, isocyanide-based MCRs such as the Passerini and the Ugi reactions were conducted with amino acid derived monomers, which enabled at least their oligomeriations. In addition, lignin-derived chemicals, such as vanillin and syringaldehyde, were successfully combined with MCR-based polymer synthesis. As a result, the successful Kabachnik-Fields three component reaction of the polymers featuring vanillin and syringaldehyde proceeded with a practically perfect consumption of the starting aldehydes, essentially affording polymeric α-amino phosphonates. These results should pave the way toward sequence-regulated constructions of polymers starting from bio-renewable compounds.<br />研究課題/領域番号:16K17912, 研究期間(年度):2016-04-01 - 2018-03-31 続きを見る
