色素をドープした高分子/液晶複合膜（PLCF）における光散乱の評価

抄録

A Polymer/Liquid Crystal Composite Film (PLCF) has excellent extinction and polarization independence at both visible and infrared wavelengths when dichroic dyes are doped. A quenching mechanism of the dye-doped PLCF has not been fully investigated. We measured optical intensities at several scattering angles to evaluate the light scattering characteristic of the dye-doped PLCFs. The extinction ratio dependence on wavelength and on scattering angle shows that light scattering in the dye-doped PLCF is dominated by two or more scatterings and that optical absorption happens at the same time.
