Surface treatment using UV irradiation was carried out to improve optical properties of polarizing
films. The effects of UV energy of the UV-treated PVA films were investigated by measuring reflectance, surface
roughness, contact angles, ESCA, and ATR. Reflectance decreased at wavelength of 450 nm or less and surface
roughness increased with increasing UV energy. Water contact angle increased in the irradiated PVA films and
surface energy decreased with increase in UV energy. ATR analysis showed that the OH groups were broken and
some new groups were introduced such as C=C and C=O bonds together with increased O1s/C1s, resulting in the
observed surface modification effect. Surface modified PVA polarizing films showed improvement in light
transmittance of polarizing films at high wavelength region without deteriorating polarization efficiency, which was
not affected by UV irradiation sequence during manufacturing processes such as coloring and drawing. |
