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化来开发先进的功能性纳米复合材料。这种杂化物的成功实例包括将层状双氢氧化物纳米掺入到乙酸纤维素的可混溶聚合物共混物系统中，合成显示各向异性磁化行为的氧化铁嵌入的多糖复合物，在液晶纤维素衍生物/聚合物网络系统中将羟基磷灰石沉积到层状物上，以及通过作为溶剂成分的烷氧基硅烷的溶胶-凝胶转化制备压印有纤维素衍生物的手性结构的光学手性二氧化硅整料。

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.
