| titleOfInvention | A 3D printable chitosan/hectorite composite hydrogel and its preparation method and application |
| abstract | The invention discloses a 3D-printable chitosan/hectorite composite hydrogel, a preparation method and application thereof. The method comprises: adding methacrylic anhydride into chitosan (or its derivatives) solution to react under heating conditions, dialyzing and freeze-drying to obtain methacrylic modified chitosan or its derivatives; Dissolve the photoinitiator, hectorite powder and methacrylic modified chitosan (or its derivatives) successively in water, stir evenly and heat in a water bath to obtain a printable hydrogel ink; the above hydrogel The three-dimensional scaffold is obtained by 3D printing according to the set shape, and the printed scaffold is cured by ultraviolet light for a certain period of time. The shape of the hydrogel scaffold can be designed, has good mechanical properties and biological properties, has no cytotoxicity and can promote cell growth. Compared with the prior art, the invention uses low-content hectorite to prepare 3D-printable chitosan composite hydrogel, and the preparation method is simple and feasible, and can be popularized and applied. |
