Functional Network Formation of Cellulosic Polysaccharides and Their Novel Hybridization with Inorganic Compounds

本研究旨在通过纤维素多糖与无机化合物的新型杂交，为开发具有先进功能的纳米复合材料提供有用的信息。这种混合物的成功例子包括：将层状双氢氧化物纳米结合到醋酸纤维素的混溶聚合物体系中，合成具有各向异性磁化行为的氧化铁包埋多糖复合材料，在液晶纤维素衍生物/聚合物网络体系中将羟基磷灰石沉积在胆甾层上，以烷基氧基硅烷为溶剂组分，通过溶胶-凝胶转化制备具有胆甾酯结构的纤维素衍生物光学手性硅块。

This research aimed at obtaining useful information to develop advanced functional nanocomposites by novel hybridization of cellulosic polysaccharides with inorganic compounds. Successful examples of such hybrids included nanoincorporation of layered double hydroxides into a miscible polymer blend system of cellulose acetate, synthesis of iron oxide-embedded polysaccharide composites showing anisotropic magnetization behavior, hydroxyapatite deposition onto cholesteric stratums in a liquid-crystalline cellulose derivative/polymer network system, and fabrication of optically chiral silica monoliths imprinted with a cholesteric structure of cellulose derivatives via sol-gel conversion of alkoxysilane as solvent constituent.
