| titleOfInvention | Method for preparing lignin-based medical slice sponge material by adopting electrolytic method |
| abstract | The invention belongs to the technical field of bio-based medical materials, and particularly relates to a method for preparing a lignin-based medical slice sponge material by adopting an electrolytic method. The solubility of lignin is improved by adding alkali, the technical difficulty that the lignin is difficult to dissolve and process is improved, sodium sulfate decahydrate is heated and melted to decompose gas in the electrolytic foaming process, air holes are formed, meanwhile, moisture is evaporated, a semi-finished viscose sponge is formed, then the semi-finished viscose sponge is quickly immersed into dilute sulfuric acid, residual sodium hydroxide in the dilute sulfuric acid is neutralized, and then the medical slice sponge is prepared. The preparation method is simple, and the prepared lignin-based medical thin-sheet sponge material has the advantages of good hydrophilicity, softness, comfort, no stimulation to skin and the like. |
