Method for preparing functional material of regenerated cellulose

Abstract

This invention publishes a preparation method for functionalized regenerated cellulose materials. Natural cellulose raw materials are dried and mixed with cellulose solvents, and the mixture is heated and stirred or mechanically kneaded until complete dissolution of cellulose. Functionalized fillers are added into the consequent homogeneous and transparent cellulose solution and stirred. The consequent solution is defoamed in vacuum, regenerated in coagulation bath, washed with water and dried or spun so as to obtain functionalized regenerated cellulose materials.

Description

technical field

[0001] The invention relates to a method for preparing functionalized regenerated cellulose materials. Background technique

[0002] With the increasing global environmental pollution and the threat to sustainable development caused by the rapid depletion of petroleum energy and natural resources, as well as the improvement of public environmental awareness, the research on polymer materials based on natural renewable resources has been developed rapidly. Cellulose is the most abundant natural polymer on earth. It is both available and renewable, and has the advantages of being cheap, degradable and non-polluting to the ecological environment. At present, cellulose-based materials have been widely used in traditional industries such as plastics, textiles, and papermaking, and have important applications in the fields of food chemicals, daily chemicals, medicine, construction, oilfield chemistry, and biochemistry. It is expected that in the coming days, cellu...
