| titleOfInvention | Preparation method and application of high-strength oriented polyvinyl alcohol hydrogel |
| abstract | The invention belongs to the technical field of intelligent high polymer materials, and relates to a preparation method and application of high-strength oriented polyvinyl alcohol hydrogel. The invention relates to a high-strength oriented polyvinyl alcohol hydrogel, which is prepared by adding deionized water into polyvinyl alcohol powder for dissolution, performing freeze-thaw cycle, pre-stretching orientation and freeze drying to obtain polyvinyl alcohol aerogel, and then soaking the polyvinyl alcohol aerogel in aqueous solution of salt with Hofmann effect or aqueous solution of salt capable of forming coordinate bonds or aqueous solution of polycarboxyl compound capable of forming hydrogen bonds with polyvinyl alcohol, wherein the tensile strength of the polyvinyl alcohol aerogel is up to 41.0 MPa, the elongation at break is up to 228.0%, and the toughness of the polyvinyl alcohol aerogel is up to 49.94 MJ/m 3 Meanwhile, the polyvinyl alcohol hydrogel has the effects of bacteriostasis, corrosion prevention and free radical removal, and has important significance for widening the application of the polyvinyl alcohol hydrogel in the biomedical material fields of artificial muscles, cartilages, tissue engineering and the like. |
