| titleOfInvention | Printable composite hydrogel with high toughness, preparation method and application |
| abstract | The invention provides printable composite hydrogel with high toughness, and a preparation method and application thereof. The invention adopts monomer containing methacryl group to prepare modified gelatin, and adopts catalytic oxidation system to process to obtain modified cellulose nanocrystalline; and mixing the prepared modified gelatin and the modified cellulose nanocrystals, and reacting under a catalytic condition to obtain the printable composite hydrogel with high toughness. Stronger covalent bond and hydrogen bond double-crosslinking network are formed between the modified cellulose nanocrystal and the modified gelatin, so that the mechanical strength of the hydrogel is greatly improved, meanwhile, the dispersibility of the modified nanocrystal is better, and the stem cells are favorably differentiated and expressed to cartilage after being synthesized. Therefore, the composite hydrogel is suitable for preparing biomedical engineering materials for tissue repair. |
