Polybenzazole precursor film, polybenzazole film and method of producing the same

摘要

The first film of the present invention is a film produced by solidifying a polybenzazole precursor that has been oriented in a given direction by the application of a magnetic or electric field. The second film of the present invention is a film produced by solidifying a polybenzazole that has been oriented in a given direction by the application of a magnetic or electric field. The first and second films have a strong anisotropy.
