| Abstract: | 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. |
