| titleOfInvention | Preparation method and application of high-thermal-conductivity boron nitride modified polyimide material |
| abstract | The invention relates to the technical field of polyimide and discloses a high-heat-conductivity boron nitride modified polyimide material, wherein an alkynyl functional group of alkynyl-terminated polyimide and an azide functional group of nano boron nitride generate alkyne-azide click reaction, the nano boron nitride and the polyimide are covalently grafted through the connection of chemical bonds, the interface affinity and compatibility of the nano boron nitride and the polyimide are obviously enhanced, the nano boron nitride is dispersed in a polyimide material matrix, the agglomeration and aggregation of the nano boron nitride are avoided, the heat conductivity coefficient and the heat conductivity of the material are improved, meanwhile, the nano boron nitride forms a good interface polarization effect in the polyimide matrix, the dielectric constant of the material is improved, the relaxation loss and the dielectric loss of the material are reduced, and the boron nitride modified polyimide material shows excellent dielectric property. |
