| 摘 要： | Azoxy dyes and their copper complexes with maximum dichroism in the spectrum range from 550nm to 700nm were synthesized and used to prepare polyvinyl alcohol （PVA） polarizing films. These films showed excellent polarizing ability. In addition, a neutral gray polarizing film was prepared by mixing synthesized dichromatic dyes with other dyes. The obtained polarizable film for gray shade was little pervious to light over the visible radiation wavelength region, ranging from 400nm to 700nm at cross state, and excellent in the polarizing activities and stable to moisture and heat.
