| 摘 要： | 以偶氮聚合物光致表面起伏光栅为模板,制备聚二甲基硅氧烷(PDMS)弹性印章,再以可溶性聚酰亚胺(PI)为“墨水”,在石英玻璃上压印出具有规则起伏结构的PI薄膜.由此制备的PI薄膜显示出很好的使液晶分子定向排列的效果.此方法成本低、效率高,是一种实用的液晶定向层薄膜制备方法.

| Abstract: | Elastomeric replica surface relief structures were prepared by molding poly(dimethylsiloxane)(PDMS)elastomers on the photo-inscribed surface-reliefgratings of azo polymer film.Then polymide(PI) solution was microcontact printing with the elastomeric PDMS on quartz slides.Good surface-relief-grating structures were formed on the quartz slides.Then the quartz slides covered with surface-relief-grating PI films were assembled to liquid crystal(LC) cell.The transmittance passing through the cell between crossed polarizers changed periodically with a regular 90° separation of the rotational angle.The pretilt angle of the cell was found to be 2.8°.The results showed that the PI film with surface-relief-grating structures by microcontact printing process has good liquid crystal alignment ability.This alignment method can be considered as potentially useful technology in the future LC display(LCD) industry. |
