| titleOfInvention | Hydrogel composite material for 3D printing and preparation method and application thereof |
| abstract | The invention discloses a hydrogel composite material for 3D printing and a preparation method and application thereof. The invention firstly discloses a hydrogel composite material for 3D printing, which comprises the following components in percentage by mass: 10 to 40 percent of PEG modified chitosan, 10 to 40 percent of gelatin and 30 to 60 percent of alpha-cyclodextrin. The invention further discloses a preparation method and application of the hydrogel composite material. When the hydrogel composite material is used for 3D printing, a supermolecular hydrogel system is formed by PEG and alpha-cyclodextrin before printing in a dual physical crosslinking mode, and the residual amino groups of the printed chitosan and the amino groups in the gelatin and beta-sodium glycerophosphate form ionic crosslinking, so that the strength of the hydrogel model structure after printing is improved, and the hydrogel composite material has good printability, biocompatibility and operability. |
