摘要

采用脉冲激光烧蚀技术在氧化铟锡(ITO)涂层玻璃和Si(100)衬底上制备了取向良好的聚乙烯(PE)薄膜。采用x射线衍射(XRD)、傅里叶变换红外光谱(FTIR)和原子力显微镜(AFM)对膜进行了表征。用向列相液晶4′-正戊基-4-氰联苯(5CB)显示薄膜的取向特征。在实验的基础上,对聚合物薄膜的形成过程进行了描述。这种高取向聚合物薄膜在集成光学和液晶显示等领域具有广泛的应用前景。

Deposition of oriented polymer films for liquid crystal alignment by pulsed laser ablation
Well oriented polyethylene (PE) films were prepared on glasses coated with Indium Tin oxide (ITO) and on Si(100) substrates by pulsed laser ablation. The films were characterized by X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy and atomic force microscopy (AFM). Nematic liquid crystal 4'-n-pentyl-4-cyanobiphenyl (5CB) is used to display the orientation features of the films. Based on the experiments, a picture is presented about the formation of the polymer films. It is expected that the as-deposited highly oriented polymer films will find various applications in integrated optics and liquid crystal displays.
