| titleOfInvention | Ferroferric oxide-graphene-cellulose conductive composite aerogel applied to field of electromagnetic shielding and preparation method thereof |
| abstract | The invention discloses ferroferric oxide-graphene-cellulose conductive composite aerogel applied to the field of electromagnetic shielding and a preparation method thereof. The preparation method comprises the following steps: dissolving cellulose in an aqueous solution of sodium hydroxide/urea, mixing an aqueous solution of graphene oxide with a cellulose solution, casting to form a film to obtain hydrogel, performing in-situ reduction by using a reducing agent, sequentially soaking the hydrogel in an aqueous solution of ferric chloride and ferrous chloride and an aqueous alkali solution to generate ferroferric oxide in situ, washing the ferroferric oxide-graphene-cellulose conductive composite aerogel for the field of electromagnetic shielding by using deionized water for multiple times, and performing freeze drying to obtain the ferroferric oxide-graphene-cellulose conductive composite aerogel applied to the field of electromagnetic shielding. The aerogel provided by the invention has a good electromagnetic shielding effect. The preparation method provided by the invention has the advantages of simple process, convenient operation, no environmental pollution and the like. The composite aerogel provided by the invention can be applied to the fields of electromagnetic shielding materials and the like. |
