POLYIMIDE FILM AND MANUFACTURING METHOD THEREOF |
摘要 |
<p>The present invention provides a polyimide film whose content of residual volatiles is reduced to not more than 0.45 weight % on the basis of the film, and further a polyimide film whose content of residual volatiles is reduced to not more than 0.45 weight % on the basis of the film and whose oxygen/carbon ratio in the surface layer is increased by 0.01-0.1, and manufacturing methods therefor. According to the present invention, it is possible to provide a polyimide film improved in adhesion performance in a stable and homogeneous manner, and this improvement of adhesion performance is attainable in the film-forming process, not in a separate process of after-treatment.</p> |
