Abstract :
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
