Abstract: Disclosed is a method of fabricating a graphite sheet, including: polymerizing diamines and a dianhydride to form a polyamic acid. The polyamic acid is solvent casted on a substrate and hot baked to form a polyamic acid film or gel film. The polyamic acid film or gel film is biaxially stretched at a high temperature imidization or chemical imidization to form the polyimide film. The polyimide film is then carbonized and graphitized to form a graphite sheet. The diamines include a diamine of Formula 1 and a diamine of Formula 2, and the dianhydride includes a dianhydride of Formulae 3, Formula 4, Formula 5, Formula 6, Formula 7, Formula 8, Formula 9, or combinations thereof.

Abstract translation: 公开了一种制造石墨片的方法，包括：聚合二胺和二酐以形成聚酰胺酸。 将聚酰胺酸溶剂浇铸在基材上并热烘烤以形成聚酰胺酸膜或凝胶膜。 聚酰胺酸膜或凝胶膜在高温酰亚胺化或化学酰亚胺化下双轴拉伸，形成聚酰亚胺膜。 然后将聚酰亚胺膜碳化并石墨化以形成石墨片。 二胺包括式1的二胺和式2的二胺，二酐包括式3，式4，式5，式6，式7，式8，式9或其组合的二酐。
