Abstract:
The present disclosure provides a polyimide film prepared from a precursor composition containing a polyamic acid and an organic solvent and having a value of (first FWHM−second FWHM)/(first FWHM+second FWHM) which is less than 0.4, a graphite sheet prepared from the polyimide film, and a method for preparing a graphite sheet.

Claim (Index 1):
A polyimide film prepared from a precursor composition containing a polyamic acid and an organic solvent and having a value of the following Formula 1 less than 0.4:\n (first FWHM\u2212second FWHM)/(first FWHM+second FWHM) \u2003\u2003Formula 1 wherein, when a diffraction peak of (010) plane according to XRD analysis of the polyimide film is in the form of a single peak, the first FWHM(full width at half maximum) indicates a FWHM of the single peak; and when the diffraction peak of (010) plane is in the form of a plurality of single peaks or in the form of a plurality of single peaks overlapped with each other, the first FWHM indicates an average of individual FWHMs of the single peaks, and when a diffraction peak of (102) plane according to XRD analysis of the polyimide film is in the form of a single peak, the second FWHM indicates a FWHM of the single peak; and when the diffraction peak of (102) plane is in the form of a plurality of single peaks or in the form of a plurality of single peaks overlapped with each other, the second FWHM indicates an average of individual FWHMs of the single peaks, wherein the polyamic acid is contained in an amount 15 to 20% by weight based on the total weight of the precursor composition, and a film intermediate derived from the precursor composition is stretched at least once.
