摘要
丙烯酰胺 (AM)与丙烯酸 (AA)对羧甲基纤维素 (CMC)进行接枝改性 ,并将其与硅溶胶进行原位杂化制得高吸水性材料 .通过红外 (FTIR)与扫描电镜 (SEM)表征其结构 ,用TGA分析硅溶胶用量变化对材料热性能的影响 .同时 。
The present work begins with the graft modification of carboxymethyl cellulose (CMC) by acrylamide and aerylic acid.The in situ hybridization of modified CMC with silica results in a hybrid material with high water absorbability. The structure of this hybrid material is characterized by FTIR and SEM; the influence of the change of silica amount on the thermal property is analysed by thermogravimetry. In addition, the influence of the change of silica amount on water absorbency is studied.
