| titleOfInvention | Preparation method of polyimide film, and the polyimide film thereby |
| abstract | The present invention relates to a process for producing a polyimide film by colorless and transparent polyimide by imidizing the polyamic acid solution at a relatively low temperature and then using the polyimide to form a polyimide film which is colorless and transparent as well as flexible and can be used for display purposes The present invention relates to a process for producing a polyimide film and a polyimide film produced by the process, which comprises the steps of: (a) preparing a solution of polyamic acid by adding dianhydride and diamine into a solvent, step;n(b) adding a chemical dehydrating agent and a catalyst to the prepared polyamic acid solution; (c) preparing a polyimide solution by imidizing the polyamic acid solution at 20 to 80 캜; (d) applying the prepared polyimide solution to a substrate; And (e) drying the applied polyimide solution to produce a polyimide film; . |
