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, the polyimide film in which: the full width at half maximum (FWHM) (deg., 2θ) of a peak is 30° to 37° in an X-ray diffraction analysis with respect to the plane direction; and the Herman's orientation index (fc) of a predetermined formula 1 is 0.06 to 0.20 in an X-ray diffraction analysis with respect to the thickness direction.
L'invention concerne un film de polyimide pour une feuille de graphite, et une feuille de graphite fabriquée à partir de celui-ci, film de polyimide dans lequel : la largeur totale à mi-hauteur (LTMH) (deg, 2θ) d'un pic est de 30° à 37° dans une analyse de diffraction des rayons X par rapport à la direction du plan ; et l'indice d'orientation de Herman(fc) d'une formule prédéterminée 1 est de 0,06 à 0,20 dans une analyse de diffraction des rayons X par rapport à la direction de l'épaisseur.
면 방향에 대한 X선 회절분석시 (002) 피크의 반치폭(full width at half maximum: FWHM)(deg., 2θ)이 30° 내지 37°이고, 두께 방향에 대한 X선 회절분석시 소정의 식 1의 헤르만 배향도(Herman's orientation index, fc)가 0.06 내지 0.20인, 그라파이트 시트용 폴리이미드 필름 및 이로부터 제조된 그라파이트 시트가 개시된다.
