Polyimide film and manufacturing method thereof |
| abstract |
The present invention relates to a high-thickness polyimide film having a reduced number of bubbles and controlled surface roughness, and a method for producing a polyimide film comprising the same, and a dianhydride component including pyromellitic dianhydride (PMDA) and diamino Provided is a polyimide film obtained by imidizing a polyamic acid solution containing a diamine component composed of diphenyl ether (ODA) and paraphenylene diamine (PPD), and including spherical silica particles and a phosphorus compound. |
