| titleOfInvention | Polyimide polymer containing selenium and its preparation method and application |
| abstract | The present invention provides a kind of preparation method and applications of the polyimides containing selenium of high refractive index, and method includes: that selenide diamine monomer polymerize to obtain polyamic acid containing selenium with dianhydride monomer by (1)；(2) polyamic acid containing selenium obtained in step (1) is obtained into polyimide polymer containing selenium through hot imidization.In the present invention, selenium element is introduced in polyimides can be improved refraction index, and refraction index value is 1.7-1.82, greatly improves the not high defect of existing polyimide material refraction index, extend it in the application of optical field. |
