摘要：

Polyethylene (PE) coatings were prepared by a method of pulse laser-assisted electron beam deposition, using low-density polyethylene as evaporated target, silicon wafer and polytetrafluoroethylene (PTFE) sublayer as substrates. The as-deposited PE coatings were characterized by attenuated total reflectance-Fourier transform infrared spectroscopy (ATR-FTIR) and atomic force microscope. Significant crystallinity increase and root mean square (RMS) roughness decrease of PE coatings were observed in the presence of PTFE sublayer. Laser-assisted deposition increased the crystallinity and mean particle diameter of PE coatings and remarkably, the obtained PE coatings had a relative uniform particle size. These results suggested that pulse laser and PTFE sublayer might contribute to the synthesis of polymer coatings with suitable crystallinity and uniform surface structure. (C) 2011 Elsevier B.V.
