| titleOfInvention | Preparation method of nanocellulose ammonia gas induction aerogel |
| abstract | The invention provides a nanocellulose ammonia gas induction aerogel with high specific surface area and a preparation method thereof. (1) Pretreatment of eucalyptus sulfate bleached pulp to prepare nanocellulose hydrogel; (2) Polyethylene The alcohol solution is added to the prepared nanocellulose hydrogel to prepare the polyvinyl alcohol/nanocellulose composite hydrogel; (3) the red radish pigment is fixed in situ on the polyvinyl alcohol/nanocellulose composite hydrogel The polyvinyl alcohol/red radish pigment/nanocellulose composite hydrogel was prepared on the fiber of the glue; (4) the polyvinyl alcohol/red radish pigment/nanocellulose composite aerogel was prepared by vacuum freeze-drying. The invention greatly enhances the adsorption capacity of ammonia gas and shortens the response time. The pH color responsiveness of radish red pigment plays a color indication role for the presence of ammonia gas, which can effectively monitor ppm level ammonia gas, and has good practicability in the field of food freshness indication. |
