  • POLYIMIDE FILM FOR GRAPHITE SHEET, MANUFACTURING METHOD THEREFOR, AND GRAPHITE SHEET MANUFACTURED THEREFROM
    Publication number: 20220396676
    Abstract: Disclosed herein are a polyimide film for graphite sheets, a method of fabricating the same, and a graphite sheet fabricated using the same. The polyimide film is fabricated by imidizing a polyamic acid formed by reaction between a dianhydride monomer and a diamine monomer, wherein the reaction is carried out in the presence of a metal compound and the polyamic acid forms a chelate with metal ions.
