本文系统地研究了冷SF6等离子体处理对聚对苯二甲酸乙二酯（PET）纤维表面改性的影响。在不同的操作条件下，等离子体处理的纤维所观察到的润湿性修改相关的染色性修改和表面化学组成的变化，通过X-射线光电子能谱（XPS），和地形，原子力显微镜（AFM）研究。从SF6等离子体在不同压力下的光发射光谱给出了其氟原子含量的信息。观察到在增加的亲水性和高可染性与增加的疏水性之间的显著转变，所述增加的亲水性和高可染性由在低压（< 0.2毫巴）下的等离子体处理赋予，主要是由于表面蚀刻和表面活化，所述增加的疏水性由在较高压力范围（0.2-0.4毫巴）下的等离子体处理赋予，结果是延长的表面润湿。
Surface modification induced on poly(ethylene terephthalate) (PET) fibers by cold SF6 plasma treatment has been investigated systematically as a function of plasma device parameters. The observed wettability modifications of fibers plasma-treated under different operating conditions were correlated to their dyeability modifications and to the changes in surface chemical composition, determined by X-ray Photoelectron Spectroscopy (XPS), and topography, investigated by atomic force microscopy (AFM). Optical emission spectra from the SF6 plasma at different pressures gave information on its content of fluorine atoms. A striking transition was observed between the increased hydrophilicity and high dyeability, imparted by plasma treatment at low pressure (< 0.2 mbar), mainly as a consequence of surface etching and surface activation, and the increased hydrophobicity, imparted by plasma treatment in the higher pressure regime (0.2-0.4 mbar), consequent to extended surface fluorination.
