Polyimide-polybenzoxazole precursor solution, polyimide-polybenzoxazole film, and preparation method therefor |
| abstract |
A polyimide-polybenzoxazole precursor solution, a polyimide-polybenzoxazole film, and a method of manufacturing the film are disclosed. A polyimide-polybenzoxazole film manufactured using the polyimide-polybenzoxazole precursor solution is formed by copolymerizing a unit structure of diamine and dianhydride and a unit structure of diaminophenol and dicarbonyl chloride in an organic solvent. The film is colorless and transparent, like conventional polyimide films, and can exhibit improved heat resistance and low birefringence. |
