| titleOfInvention | A kind of method preparing high-strength chitosan/cellulose composite hydrogel film |
| abstract | The invention discloses a kind of method preparing high-strength chitosan/cellulose composite hydrogel film, by weight percentage containing measuring chitosan, Mierocrystalline cellulose, lithium hydroxide, sodium hydroxide, urea and water, said components is mixed, through swelling, freezing, thaw, filter, centrifugal, deaeration, obtain hyaline test glycan/cellulose alkaline system solution; Chitosan/Cellulose alkaline system solution is injected into film die, is bathed in precipitation bath, form Chitosan/Cellulose aquagel membrane.Preparation technology of the present invention is simple, and with natural biological macromole chitosan and Mierocrystalline cellulose for raw material prepares high intensity hydrogel film, and chitosan and Mierocrystalline cellulose are without special modification or modified with functional group, are all present in described gel with non-derived thing form.Use alkaline system solution, while acquisition high-strength composite gel-film, avoid the unstable that acid-catalyzed hydrolysis in acidic chitosan solution brings, and use toxic organic solvents bio-medical field to be applied to the restriction brought. |
