一种纤维素基自组装水凝胶制备体系的构建与功能化初步研究

The efficiently application of cellulose is an important area of the study on natural polymers.In this area, new materials and new methods for preparation are the main way to achieve the natural polymers efficiently application. In this project,for building a novel preparation system of cellulose self-assembled hydrogel, modified soluble cellulose is used as polymer chain, poly-cyclodextrin with topology structure of line type is used as hydrophilic group and functional guest carrier, the encapsulation ability of cyclodextrins is used as the driving force for hydrogel self-assebling, the functional cellulose self-assembled hydrogel will be finally prepared with the controllable preparation and fine water retention ability. For investigating the new materials and new preparation methods of the cellulose hydrogel and obatined the scientific data,the studys including the composition, structure, gelling mechanism, structure-property relationship of cellulose self-assembled hydrogel, the method for preparating cellulose self-assembled hydrogel and dynamic mechanisms of encapsulating and release of functional guest molecules will be preformed.
