| titleOfInvention | A kind of light-weight large-size graphene electromagnetic shielding film and preparation method thereof |
| abstract | The present invention perfectly repairs graphene defects by using a super large sheet of graphene oxide to form a film and annealing it at a high temperature, minimizes edge defects, forms a perfect large conjugated structure, and ensures the thermal conductivity of graphene The passage is unblocked; further through the three-step independent heating process, the functional groups on the graphene surface are gradually separated, and the pore-forming agent intercalated between the graphene sheets is slowly decomposed, both of which are gradually released in the form of gas, and at the same time, graphitization The process unfolds one by one to form graphene micro-airbags; during the formation of the micro-airbags, the most stable functional groups on the graphene surface also fall off, and the gas expands at high temperature, resulting in 1-4 layers of graphene sheets. Graphene structure; the successful introduction of graphene few-layer structure greatly improves the electrical conductivity of the material. The micro-airbag structure is assisted by better electrical conductivity, so that the graphene film of the present invention has extremely strong electromagnetic shielding performance. |
