Graphite Sheet Having Excellent Thermal Conductivity and Method for Preparing The Same

WON DONG YOUNG / LIM HYUN JAI / KIM KYUNG SU

The present invention relates to a manufacturing method of a graphite sheet with high performance by carbonizing and/or graphitizing a polyimide film manufactured by imidizing a polyamic acid formed by reaction of a dianhydride monomer and a diamine monomer, and a graphite sheet with high performance manufactured therefrom. The polyimide film includes two or more fillers having different average particle diameters. The thermal conductivity is 1,400 W/m·K or more.

본 발명은, 이무수물 단량체와 디아민 단량체의 반응에 의해 형성된 폴리아믹산을 이미드화하여 제조되는 폴리이미드 필름을 탄화 및/또는 흑연화시켜 고성능 그라파이트 시트를 제조하는 방법으로서, 상기 폴리이미드 필름은 평균 입경이 상이한 2 이상의 필러를 포함하고, 열전도도가 1,400 W/m·K 이상인 고성능 그라파이트 시트의 제조방법 및 이를 통해 제조된 고성능 그라파이트 시트를 제공한다.
