POLYIMIDE COMPLEX, POLYAMIC ACID SOLUTION, METHOD FOR MANUFACTURING POLYIMIDE COMPLEX, AND FILM PRODUCED FROM POLYIMIDE COMPLEX

摘要

The objective of the present invention is to provide a polyimide complex that emits fluorescence having a specific wavelength and achieves high fluorescence intensity as a result of being irradiated with ultraviolet rays without compromising the colorless transparency, mechanical properties, and heat resistance of a polyimide having a specific structure, and to provide a method for manufacturing the complex. This polyimide complex is obtained by adding 0.001-4 parts by weight of a europium (Eu) compound per 100 parts by weight of a polyamic acid solution (S1) obtained from a specific polyamic acid obtained from an alicyclic diamine compound (A) and an aromatic tetracarboxylic dianhydride (B) as well as a solvent (C) in which the polyamic acid dissolves, obtaining a polyamic acid solution (S2), and imidating the polyamic acid contained in the polyamic acid solution (S2) and removing the solvent (C).
