| Abstract: | In this paper, polarizing films were prepared by means of flowing. Optical properties of polarizing film only containing iodine, and optical properties of polarizing film containing iodine, nickel and cobalt were studied by optical apparatus, which can detach visible light. The results show that polarizing film containing nickel and cobalt has higher transmittance, single polarizing coefficient and combinatorial polarizing coefficient. When combined in perpendicular direction, wave crest of the leaking light moves left. |
