| titleOfInvention | Superfine composite fiber film, preparation method and use thereof |
| abstract | The invention relates to a biodegradable and bioabsorbable superfine composite fiber film, which consists of poly lactic-co-glycolic acid of the weight ratio ranging from 75wt% to 100wt% and poly latic acid-b-polyethylene glycol of the weight ratio ranging from 0wt% to 25wt%. The preparation method includes the following steps of mixing the poly lactic-co-glycolic acid and the poly latic acid-b-polyethylene glycol into N, N-dimethylformamide or acetone or mixture of the N-dimethylformamide and the acetone so as to obtain uniform polymer solution, then stirring the uniform polymer solution at room temperature to obtain uniform mixed liquid, and finally injecting the uniform mixed liquid into an electrostatic spinning device to conduct electrostatic spinning, and accordingly the poly lactic-co-glycolic acid and the poly lactic acid-b-polyethylene glycol superfine composite fiber film is obtained. The superfine composite fiber film has excellent biocompatibility and adjustable biodegradation, has the advantages of light and soft texture and fine permeability simultaneously, and can be used as excellent internal adhesion-proof materials. |
