摘要：

A series of perylene-containing polyimides and copolyimides have been synthesized and characterized by DSC, TGA, NMR, UV-vis, and X-ray powder diffraction measurements. Xerographic electrical measurements indicated that perfectly alternating copolyimides had higher photosensitivities than those of homopolyimides and random copolyimide. After annealing, polyimide films showed a redshift in UV-vis absorption and improved photosensitivity due to an increase in crystallinity, as indicated by wide-angle X-ray diffraction measurements.
