长期以来，在标准的聚对苯二甲酸乙二醇酯(PET)瓶子的内壁上增加一层不透气的涂层，一直被认为是改善啤酒、果汁和碳酸软饮料包装的一种方法。我们开发了一种等离子体辅助沉积工艺，适用于在PET表面沉积100 nm厚的透明氢化非晶碳(a-C：H)薄膜。西德尔等离子体技术使用乙炔气体前体和微波等离子体，使我们能够获得工业工艺流程所需的60 nm/S的高沉积速率。A-C：H膜使O-2的渗透率降低了50倍。用卢瑟福背散射(RBS)、弹性反冲检测分析(ERDA)、X射线光电子能谱(XPS)、光学光谱、拉曼光谱和电子顺磁共振(EPR)对a-C：H薄膜的成分、光学性质、结构和缺陷进行了表征。(C)2005 Elsevier B.V.保留所有权利。
The addition of a gas-impermeable coating on the inside wall of a standard polyethylene tereplithalate (PET) bottle has long been considered as a way to improve the packaging for beer, juice and carbonated soft drinks. We have developed a plasma-assisted deposition process suitable for the deposition of 100 nm thick, transparent, hydrogenated amorphous carbon (a-C:H) films on PET surfaces. The Sidel plasma technology uses an acetylene gas precursor and a microwave plasma, which allows us to obtain a high deposition rate of 60 nm/s necessary for industrial process flows. The a-C:H films provide a 50-fold reduction of the permeation rates Of O-2 . The composition, optical, structural and defect properties of the a-C:H films were characterized by Rutherford Back Scattering (RBS), Elastic Recoil Detection Analysis (ERDA), X-ray Photoelectron Spectroscopy (XPS), optical spectroscopy, Raman and Electron Paramagnetic Resonance (EPR).
