A study on electrochromism of polyaniline film was reported in the previous paper. In this study, photochromism of polyaniline film supporting TiC_2 was studies. Polyaniline films supporting TiO_2 were cyclic electrodeposited to ITO glass in the aniline HCIO_4 solution in which TiO_2 powders dispersed. Polyaniline film supporting TiO_2 was black blue in dark and was turned to white green by irradiation of Hg-lump. But its colorchange was irreversible. Then, polyaniline derivatives as N-methylaniline (blue), o-phenylenediamine (red) and, some photocatalysts such as ZnO, V_2O_3, WO_3) which have different EC, Ev and Eg value were tried to use in photochromic system to change the color reversible. But, we have no good results, then by combining photochromism with electrochromism, we tried to have reversible color change system in these polyaniline films supporting TiO_2.
