Outline of Final Research Achievements |
This study established a technological foundation to accelerate the social implementation of cellulose nanofibers (CNFs). Two primary approaches were undertaken: utilizing the large surface area of CNFs to improve the water solubility of poorly soluble compounds and developing a conductive ink using non-oxidized copper nanoparticles (CuNPs) anchored on polydopamine (PDA) modified CNFs. Seventy poorly soluble compounds were examined for their solubilization rates in CNF dispersions, and a regression model was developed to identify key parameters for solubility improvement. Additionally, a conductive substrate was successfully fabricated using screen printing and low-temperature sintering of Cu@PDA@CNF ink, demonstrating antioxidative properties and enhanced electrical conductivity. These advancements highlight the potential of CNFs in various industries, contributing to fields such as pharmaceuticals, electronics, and environmental protection.

Academic Significance and Societal Importance of the Research Achievements |
本研究は、セルロースナノファイバー(CNF)の大表面積を活用し、難水溶性化合物の水溶性を向上させられることを明らかにした。難水溶性化合物の特性のうち,CNFで水溶性を向上させることができるものの特徴を,統計的に把握することができた。また、ポリドーパミン(PDA)修飾CNFを足場とすることで、抗酸化性と導電性を兼ね備えた銅ナノ粒子インクを開発した。これにより、CNFの新たな応用可能性が広がり、医薬品、電子デバイス、環境保護材料などの分野での社会的意義が大きい。
