| titleOfInvention | Attapulgite-chitosan composite gel and preparation method thereof |
| abstract | The invention relates to the field of clay deep processing, and discloses attapulgite-chitosan composite gel and a preparation method thereof, wherein the composite gel comprises the following components in percentage by mass: attapulgite clay: and (3) chitosan: glutaraldehyde: borax = 100: 12-35: 1.2-5.25: 3 to 5. The attapulgite-based composite hydrogel is prepared by taking attapulgite as a main material, chitosan as an auxiliary material, and glutaraldehyde and borax as double cross-linking agents through a sol-gel method. The composite hydrogel disclosed by the invention has an excellent three-dimensional pore structure and mechanical properties, has good adsorption, slow release performance and immobilization capacity, can be used as a medical functional material such as a mask, a medical dressing or a tissue engineering scaffold and the like, and can be further subjected to freeze-drying treatment to obtain aerogel with wider application. The aerogel prepared by the preparation process has excellent mechanical property, and the elastic modulus can be regulated and controlled within the range of 15-193 Mpa. The invention has simple process and short preparation period, and meets the requirement of large-scale production. |
