| titleOfInvention | Graphene quantum dot functionalization-based composite nano film material and gas-sensitive sensing element |
| abstract | The invention discloses a graphene quantum dot functionalization-based composite nano film material, which is in a film shape, the main body of the composite nano film material is a ZnO nanosheet, and the surface of the composite nano film material is covered with graphene quantum dots and tin dioxide quantum grains; the ZnO nanosheet as the main body is hexagonal, the average side length is 1.5-2.4 mu m, and the average thickness is 50-100 nm; the average size of the graphene quantum dots is 3.2-4.3 nm, and the average size of the tin dioxide quantum grains is 3.5-5.2 nm. The invention comprehensively uses the hydrothermal method and the post-thermal steaming method to prepare the multi-level structure sensing material, and has simple synthesis method and low cost. |
