Preparation method of polyimide-based graphite film
The invention discloses a preparation method of a polyimide-based graphite film. The polyimide-based graphite film is prepared by carbonizing and graphitizing a polyimide film. The polyimide film is prepared from diamine and dianhydride through polymerization and imidization reaction, and the diamine comprises diamine containing naphthalene rings. The polyimide-based graphite film obtained by carbonizing and graphitizing the polyimide film has excellent thermal conductivity and electrical conductivity by selecting diamine monomers in the preparation process of the polyimide film.
本发明公开了一种聚酰亚胺基石墨膜的制备方法，所述聚酰亚胺基石墨膜通过将聚酰亚胺薄膜经碳化、石墨化处理制得；所述聚酰亚胺薄膜是由二胺和二酐经聚合、亚胺化反应制备得到，其中，所述二胺包括含萘环的二胺。本发明通过对聚酰亚胺薄膜制备过程中二胺单体的选择，使得由该聚酰亚胺薄膜经碳化、石墨化后得到的聚酰亚胺基石墨膜具有优异的导热性和导电性。
