| titleOfInvention | Polyimide/graphene composite aerogel with ordered pore structure and preparation method and application thereof |
| abstract | The invention provides a polyimide/graphene composite aerogel material with an ordered pore structure, and a preparation method and application thereof. The preparation method comprises the steps of firstly preparing ammonium polyamic acid salt/graphene aqueous dispersion; and then directionally freezing and thermally imidizing the mixture. The polyimide/graphene composite aerogel disclosed by the invention has good electric conductivity, electromagnetic shielding performance, heat transfer performance and mechanical performance, and the electromagnetic shielding performance of the polyimide/graphene composite aerogel is obviously superior to that of a polymer/graphene composite material in the prior art. Meanwhile, the polyimide/graphene composite aerogel prepared by the method has the characteristic of anisotropy in conductivity, electromagnetic shielding performance, heat transfer performance and mechanical property, can meet the requirements of different properties of materials in all directions under certain complex application conditions, and endows the materials with more functional application prospects, such as wide application prospects in important fields of weaponry, aerospace, biomedicine, vibration reduction, noise reduction and the like. |
