Outline of Final Research Achievements

In the development of high-performance Japanese lacquer coatings, the most important issue is to provide UV degradation inhibiting effects to lacquer coatings. In this study, the entire process was divided into three sections: Establishment of uniform dispersion method of UV-absorbing nanoparticles in lacquer coatings, Development of coating method using structural color expression by UV-absorbing nanoparticles, and Creation of nanocomposite dry lacquer using bio-nanofiber as an aggregate. Through the realization of the goals of each category, we developed nano-composite lacquer materials with UV degradation inhibiting function by UV-absorbing nanoparticles.

Academic Significance and Societal Importance of the Research Achievements

本研究は、漆塗料の耐光性の改善を目的として、漆塗料の分解抑制に寄与するシリカシェルと漆塗料への親和性向上を意図したアルキルシェルのダブルシェル構造を有する酸化チタンナノ粒子を紫外線吸収剤として開発したことを特徴とする。さらに、漆塗料の機能向上に特化した補強材となるバイオナノファイバーのクライオゲルを作製したことで、漆塗料の欠点の克服と高付加価値化が図られ、今後その利用機会の拡大に伴う漆塗り文化の発展が期待できる。
