초록

Benzothiazole moiety를 함유하는 이색성 아조염료를 합성한 후, 염착공정에 의해 poly(vinyl alcohol)(PVA)-dye 편광필름을 제조하였다. PVA-dye 편광필름의 UV-Visible 스펙트럼은 326nm와 584nm에서 염료분자와 방향족 고리와 발색단에 해당되는 흡수밴드를 나타내었다. PVA-dye 편광필름의 편광효율과 투과도는 염료의 농도, 염착시간, 염촉매의 첨가에 의해 크게 영향을 받았다. PVA-dye 편광필름은 99.5%의 높은 편광효율과 42%의 뛰어난 투과도를 나타내었다. 특히 PVA-dye 편광필름의 열과 습도에 대한 내구성은 일반적으로 사용되는 PVA-I₂ 편광필름에 비해 우수하였다.

A novel dichroic azo having a benzothiazole moiety was synthesized and it was used to prepare poly(vinyl alcohol) (PVA)-dye polarizing film by the dyeing process. The UV-Visible spectrum of PVA-dye polarizing film showed absorption bands corresponding to aromatic rings and dye chromophoric species at 326 nm and 584 nm. The polarization efficiency and the transmittance of PVA-dye polarizing film were significantly influenced by dye concentration, dipping time and addition of salt catalyst. The PVA-dye polarizing film exhibited a high polarization efficiency of 99.5% and a good transmittance of 42%. Especially,the heat and humidity resistance of PVA-dye polarizing film was higher than that of a conventional PVA-I₂ polarizing film.

Keywords:dichroic azo dye;PVA-dye polarizing film;polarization efficiency;transmittance;heat and humidity resistance
