Black films play an important role in optics, electronics and other high-tech areas. This study aimed to produce a type of blend film that exhibits excellent mechanical properties and low transmittance. Blends of solutions were prepared by mechanical mixing a solution of poly(amic acid) (PAA) with that of polyacrylonitrile (PAN). Two types of PAA were synthesized, from BPDA/PDA/ODA and PMDA/ODA. The black films of PI/PAN were obtained by casting the solution blend onto a glass and followed by a thermal treatment. The blend films were withdrawn from the oven set at different temperatures. From these blend films, it was clearly observed that the color of the blend films changed from yellow to black. The effect of PAN content on their properties, structure and phase separation between PI and PAN were studied in detail. The blend films were characterized by Fourier transform infrared spectrometry, X-ray diffraction and universal materials tester. The results showed that imide rings were successfully formed and that the preoxidation of PAN was essentially complete. The mechanical strength decreased with increased PAN content, which was supported by the results from scanning electron microscopy (SEM) and UV-Vis light detector. The blend films were treated with a potassium hydroxide solution for 15 min. It was found that phase separation occurred between PI and PAN, revealed by observation of the surface and the cross-section morphology by SEM. With the increase in PAN content, the degree of phase separation also increased, which resulted in lower mechanical strength. This conclusion was also confirmed by the results of UV-Vis light detector. The transmittance of the blend films reduced because of the phase separation. In summary, the blend films of (BPDA/PDA/ODA)PI containing 10 wt% PAN and those of (PMDA/ODA)PI containing 20 wt% PAN exhibited excellent mechanical properties and low transmittance.
