POLYIMIDE FILM FOR GRAPHITE SHEET, AND GRAPHITE SHEET MANUFACTURED THEREFROM
Disclosed are a polyimide film for a graphite sheet, and a graphite sheet manufactured therefrom, wherein the polyimide film is prepared by imidizing a precursor composition containing: a polyamic acid formed through reaction of a dianhydride monomer and a diamine monomer; and an organic solvent, the diamine monomer containing about 30 mole% to about 70 mole% of 4,4'-methylenedianiline and about 30 mole% to 70 mole% of 4,4'-oxydianiline on the basis of the total mole number thereof, with the sum of mole numbers of 4,4'-methylenedianiline and 4,4'-oxydianiline accounting for about 85 mole% or more.
Sont divulgués un film de polyimide pour une feuille de graphite, et une feuille de graphite fabriquée à partir de celui-ci, le film de polyimide étant préparé par imidisation d'une composition de précurseur contenant : un acide polyamique formé par réaction d'un monomère dianhydride et d'un monomère diamine ; et un solvant organique, le monomère diamine contenant environ 30 % en mole à environ 70 % en moles de 4,4'-méthylènedianiline et environ 30 % en mole à 70 % en moles de 4,4'-oxydianiline sur la base du nombre total de moles de celui-ci, la somme des nombres de moles de 4,4'-méthylènedianiline et de 4,4'-oxydianiline représentant environ 85 % en moles ou plus.
이무수물 단량체와 디아민 단량체의 반응에 의해 형성된 폴리아믹산과 유기용매를 포함하는 전구체 조성물을 이미드화하여 제조되는 폴리이미드 필름이며, 상기 디아민 단량체는 디아민 단량체의 총 몰수를 기준으로 약 30 몰% 내지 약 70 몰%의 4,4'-메틸렌디아닐린과 약 30 몰% 내지 약 70 몰%의 4,4'-옥시디아닐린을 포함하고, 4,4'-메틸렌디아닐린과 4,4'-옥시디아닐린의 합계 몰수는 약 85 몰% 이상인, 그라파이트 시트용 폴리이미드 필름, 및 이로부터 제조된 그라파이트 시트가 개시된다.
