| titleOfInvention | A reduced graphene oxide/aramid fiber nanofiber composite airgel for electromagnetic shielding and its preparation method |
| abstract | The invention discloses a method for preparing reduced graphene oxide/aramid nanofiber composite airgel for electromagnetic shielding, which uses sodium bisulfite to reduce graphene oxide to prepare reduced graphene oxide; aramid fiber, hydrogen oxidized Potassium, dimethyl sulfoxide and deionized water were mixed to prepare aramid nanofiber gel; then the reduced graphene oxide was combined with aramid nanofiber gel, ultrasonically dispersed to make it uniform, and the whole was put into the refrigerator for pre-freezing, and finally Reduced graphene oxide/aramid nanofiber condensed composite aerogels with different mass ratios were prepared by freeze-drying; this method has the advantages of simple operation, easy operation, and mild reaction conditions. The reduced graphene oxide/aramid nanofiber composite airgel for electromagnetic shielding prepared by this method has both good mechanical properties and excellent electromagnetic shielding performance, making it suitable for applications in communications, microelectronics and aerospace and other special fields. |
