| titleOfInvention | A kind of cellulose-graphene aerogel material applied in the field of gas detection and preparation method thereof |
| abstract | The invention discloses a cellulose-graphene composite aerogel material used in the field of gas detection and a preparation method thereof. The preparation method includes: dissolving cotton staple cellulose in an aqueous solution of sodium hydroxide/urea, then mixing the graphene oxide aqueous solution with the cellulose solution, and casting a film to obtain a hydrogel, and after being reduced by the vitamin C aqueous solution, The cellulose-graphene hydrogel is then placed in a freeze-drier and freeze-dried to obtain a cellulose-graphene composite aerogel material. The aerogel materials provided by the present invention have different degrees of sensitivity in different volatile vapors, and can be used to detect different gases. The preparation method provided by the invention has the advantages of low dependence on equipment, simple technological process, convenient operation and no pollution to the environment. The aerogel material provided by the present invention can be used as a gas sensor in the fields of gas detection and the like. |
