  • Selenium-containing polyimide polymer, preparing method and use thereof
    Patent number: 10316144
    Abstract: The invention provides a selenium-containing polyimide polymer, preparation method and use thereof. The method comprises: (1) polymerizing a selenide diamine monomer with a dianhydride monomer to give a selenium-containing polyamic acid; and (2) performing thermal imidization on the selenium-containing polyamic acid obtained in the step (1) to give a selenium-containing polyimide polymer. In the invention, selenium is introduced into polyimides for increasing refractive index to 1.7-1.82, this greatly improves the defects of low refractive index of the existing polyimide materials, thereby expanding its applications in the optics field.
    Type: Grant
