POLYIMIDE FILM FOR GRAPHITE SHEET, MANUFACTURING METHOD THEREFOR, AND GRAPHITE SHEET MANUFACTURED THEREFROM
Disclosed are a polyimide film for a graphite sheet, a manufacturing method therefor, and a graphite sheet manufactured therefrom, wherein the polyimide film is 100㎛ or greater in thickness and has a thermal degradation temperature at 1 weight% loss of 480℃ or less as measured by thermal gravity analysis (TGA) and/or an L* value of 40 or higher as measured by a color difference meter.
L'invention concerne un film de polyimide pour une feuille de graphite, un procédé de fabrication s'y rapportant et une feuille de graphite fabriquée à partir de ceux-ci, le film de polyimide ayant une épaisseur supérieure ou égale à 100 µm et ayant une température de dégradation thermique à une perte de 1 % en poids, mesurée par analyse thermogravimétrique (ATG), inférieure ou égale à 480 °C et/ou une valeur de L*, mesurée par un dispositif de mesure de différence de couleur, supérieure ou égale à 40.
두께가 100㎛ 이상이고, 열중량 분석(TGA)으로 측정된 1중량% 감량 열분해 온도가 480℃ 이하 및/또는 색차계로 측정한 L*값이 40 이상인, 그라파이트 시트용 폴리이미드 필름, 이의 제조방법 및 이로부터 제조된 그라파이트 시트가 개시된다.
