Title (EN) TRANSPARENT POLYIMIDE FILM AND PREPARATION METHOD THEREOF
(FR) FILM TRANSPARENT À BASE DE POLYIMIDE ET SON PROCÉDÉ DE PRÉPARATION
(KO) 투명 폴리이미드 필름 및 그 제조방법
Abstract: front page image
(EN)The present invention relates to a transparent polyimide film with improved tensile strength and a preparation method thereof, and more specifically to a colorless, transparent polyimide film having excellent optical properties and improved tensile strength at the same time through the use of a monomer containing a functional group or an improver for improving tensile strength, and a preparation method thereof, wherein the functional group is selected from a group consisting of a hexafluoro group, a sulfone group, and an oxy group.
(FR)La présente invention concerne un film transparent à base de polyimide possédant une résistance à la traction améliorée, et son procédé de préparation. Plus particulièrement, l'invention concerne un film incolore et transparent à base de polyimide possédant à la fois d'excellentes propriétés optiques et une résistance à la traction améliorée, du fait de l'utilisation d'un monomère contenant un groupe fonctionnel ou un améliorant servant à améliorer la résistance à la traction, et son procédé de préparation. Le groupe fonctionnel est choisi parmi un groupe hexafluoro, un groupe sulfone et un groupe oxy.
(KO)본 발명은 인열강도가 개선된 투명 폴리이미드 필름 및 그 제조방법에 관한 것으로, 헥사플루오로기, 술폰기 및 옥시기로 구성된 군에서 선택되는 기능기를 포함하는 모노머 또는 인열강도 향상용 개선제를 사용함으로써, 무색 투명하면서 광학 특성이 우수하면서도 동시에 인열강도가 개선된 폴리이미드 필름 및 그 제조방법에 관한 것이다.
