Abstract
In this research, we accomplished in order to improving color fastness of sublimation for Poly (vinyl alcohol) (PVA)-iodine polarized film. The poor iodine sublimation problem has greatly improved by O2 low temperature plasma treatment.We obtained the followings: (1) plasma treatment has contributed in adhesive ability via peel strength, AFM image and roughness were investigated, But the improvement in adhesive strength was not linearly proportional to the treatment time. (2) O2 plasma treated PVA-iodine polarized film was good enough as to maintain the transmittance and polarization even after iodine conc. of 0.05mol/L and dipping time of 50sec. (3) O2 low temperature plasma treated PVA-iodine polarized film has obtain high durability because of good adhesive strength.
