Polyimide Film For Graphite Sheet And Graphite Sheet Prepared Therefrom
The present invention relates to: a polyimide film manufactured by imidizing a precursor composition comprising polyamic acid and an organic solvent formed by the reaction of a dianhydride monomer and a diamine monomer; and a graphite sheet manufactured from the same. More specifically, in the polyimide film for a graphite sheet of the present invention, the diamine monomer contains 30 to 70 mol% of 4,4′-methylenedianiline and 30 to 70 mol% of 4,4′-oxydianiline based on the total number of moles of the diamine monomer, and the total number of moles of 4,4′-methylenedianiline and 4,4′-oxydianiline is 85 mol% or more.
이무수물 단량체와 디아민 단량체의 반응에 의해 형성된 폴리아믹산과 유기용매를 포함하는 전구체 조성물을 이미드화하여 제조되는 폴리이미드 필름이며, 상기 디아민 단량체는 디아민 단량체의 총 몰수를 기준으로 30 내지 70 몰%의 4,4'-메틸렌디아닐린과 30 내지 70 몰%의 4,4'-옥시디아닐린을 포함하고, 4,4'-메틸렌디아닐린과 4,4'-옥시디아닐린의 합계 몰수는 85 몰% 이상인, 그라파이트 시트용 폴리이미드 필름, 및 이로부터 제조된 그라파이트 시트가 개시된다.
