| titleOfInvention | Method for preparing cellulose acetate microspheres and product prepared by method |
| abstract | The invention belongs to the technical field of chemical cellulose, and discloses a method for preparing cellulose acetate microspheres and a product prepared by the method. The method for preparing cellulose acetate microspheres comprises the following steps of dissolving a cellulose acetate tow with a plasticizer into a mixed solvent to obtain polymer slurry, then adding the obtained polymer slurry into dispersion liquid to be fully mixed to obtain suspension liquid, reducing the solubility of cellulose acetate, and separating out the cellulose acetate microspheres. The average grain diameter of the cellulose acetate microspheres is 5-1500 micrometers, the average pore size is 2-200 nm, and the specific surface area is 0.6m<2>*g<-1> to 10.0m<2>*g<-1>. The acetyl substitution degree of the cellulose acetate is 2.0-2.6, and the content of the residual plasticizer is 1.0-3.0 percent of the quality of the cellulose acetate microspheres. The microspheres have the advantages of easiness in regeneration, good biocompatibility, good hydrophily and the like. |
