제목 Water vapor barriers on polyethylene naphthalate using SiOx and ZnO plasma enhanced chemical vapor deposition
초록 Thin films of SiOx and ZnO were grown by plasma-enhanced chemical vapor deposition (PECVD) and their water vapor transmission rates (WVTR) were tested either individually or as composite films on polyethylene naphthalate (PEN) substrate. Hexamethyldisiloxane and diethylzinc was used as precursors, and oxygen was used as reactive gas. The deposition rate, X-ray diffraction, surface roughness, light transmission, and WVTR of thin films were characterized as a function of the equivalence ratio and substrate temperature. Significant improvements resulted when the ZnO PECVD film was used as interlayer between SiOx layers. The water vapor transmission rates of single layer ZnO on PEN substrate was ~ 6.0 g/m2/day but that of the multi-layered structure of SiOx/ZnO/SiOx/PEN system reduced to less than 0.10 g/m2/day. The decrease in the water vapor permeability for the composite thin layers of SiOx and ZnO was attributed to water absorbing property of ZnO film.
