(abstract)

ベーマイトナノファイバーで強化したポリメチルシルセスキオキサンマクロ多孔質モノリスは、出発組成の調整により微細構造を制御し、高い拡散反射率(400–1100 nmで約99.5%)と優れた機械的強度を実現した。シリコンフォトダイオード検出域ではスペクトラロンを上回る反射性能を示し、CNC加工や3D成形にも対応可能である。さらに撥水性と350℃までの耐熱性を備えることから、屋外でのイメージセンサーキャリブレーションなどに適した有望な光学材料といえる。

(abstract)

Polymethylsilsesquioxane macroporous monoliths reinforced with boehmite nanofibers achieved high diffuse reflectance (approximately 99.5% at 400–1100 nm) and excellent mechanical strength through microstructure control via adjustment of the initial composition. These monoliths exhibit superior reflectance performance compared to Spectralon within the silicon photodiode detection range, and they are compatible with CNC machining and 3D molding. Furthermore, their water repellency and heat resistance up to 350°C make them promising optical materials for applications such as outdoor image sensor calibration.
