| titleOfInvention | Polyvinyl alcohol-tannic acid-boric acid ternary crosslinked hydrogel, and preparation method and application thereof |
| abstract | The invention discloses a polyvinyl alcohol-tannic acid-boric acid ternary crosslinked hydrogel, a preparation method and application thereof. Polyvinyl alcohol, tannic acid, boric acid, potassium hydroxide and potassium chloride are used as raw materials, and the cross-linked hydrogel is obtained by virtue of condensation reaction between the boric acid and adjacent hydroxyl. The synthesis method has the advantages of simple process, mild conditions, easy operation and no need of post-treatment of the product. The shape memory hydrogel with different self-repairing capabilities and mechanical strengths can be obtained by changing the using amounts of polyvinyl alcohol, tannic acid, boric acid, potassium hydroxide and potassium chloride. The self-repairing shape memory hydrogel has potential application in the aspects of soft robots, artificial ligaments, flexible devices, automobile intelligent sensing materials and the like. |
