| titleOfInvention | The preparation method of a kind of polyvinyl alcohol sponge dressing |
| abstract | The present invention relates to the preparation method of a kind of dressing, particularly the preparation method of a kind of polyvinyl alcohol sponge dressing, belong to the preparing technical field of medical dressing. The present invention take polyvinyl alcohol as raw material, through epoxy addition reaction, prepares the methacrylic acidylate polyvinyl alcohol with optical active group, by uv photopolymerization, multigelation, freeze-dry process, obtains polyvinyl alcohol sponge dressing. The preparation method of the present invention makes full use of ultraviolet light polymerization and freeze-thaw technology, forms chemically crosslinked and physical crosslinking and combines three-dimensional net structure polyvinyl alcohol sponge dressing. Polyvinyl alcohol sponge dressing prepared by the method has good biocompatibility and wet strength, and meanwhile, quality is soft, and the conformability of the surface of a wound is good, and applicating property is good, can extensively for the drainage surface of a wound. |
