POLYIMIDE FILM FOR GRAPHITE SHEET AND MANUFACTURING METHOD THEREFOR
The present invention relates to a polyimide film for a graphite sheet and a manufacturing method therefor. In an embodiment, the polyimide film for a graphite sheet is formed from a composition for forming a polyimide film, the composition comprising: a polyamic acid; and an imidization catalyst, wherein the polyimide film has a thickness of about 100 ㎛ to about 200 ㎛ and a first surface damage rate, expressed by equation 1, of 0% or about 0.001% to about 0.004%. (Equation 1 is as defined in the detailed description.)
La présente invention concerne un film de polyamide pour une feuille de graphite et un procédé de fabrication associé. Dans un mode de réalisation, le film de polyimide pour une feuille de graphite est formé à partir d'une composition pour former un film de polyimide, la composition comprenant : un acide polyamique ; et un catalyseur d'imidisation, le film de polyimide ayant une épaisseur d'environ 100 µm à environ 200 µm et un premier taux d'endommagement de surface, exprimé par l'équation 1, de 0 % ou d'environ 0,001 % à environ 0,004 %. (L'équation 1 est telle que définie dans la description.)
본 발명은 그라파이트 시트용 폴리이미드 필름 및 이의 제조방법에 관한 것이다. 일 구체예에서 상기 그라파이트 시트용 폴리이미드 필름은 폴리아믹산; 및 이미드화 촉매;를 포함하는 폴리이미드 필름 형성용 조성물로부터 형성되고, 두께가 약 100 ㎛ 내지 약 200 ㎛이고, 식 1로 표시되는 제1 표면 손상률이 0% 또는 약 0.001% 내지 약 0.004% 이다. (식 1은, 상세한 설명에 정의된 바와 같다.)
