Poly(ethylene terephthalate) (PET) fibers are widely used in various fields owing to their good physical properties and chemical resistance, but PET hydrophobicity heavily compromises its use in many applications. Wet-chemical treatments are often required to induce hydrophilicity, but these can damage the polymer matrix and produce large volumes of liquid wastes. Atmospheric-pressure glow-discharge plasma (APGDP) is an alternative and ecofriendly method to obtain similar or better results with polymeric materials, compared to wet-chemical treatments. The hydrophilic behavior of PET samples is investigated after a roll-to-roll APGDP treatment by varying the plasma gas mixture, gas fluxes, and electrode temperatures. The reactive species formed in the plasma chamber are characterized by optical emission spectroscopy. The induced surface functionalization and roughness are characterized by contact-angle measurements, atomic force microscopy, and UV/Vis absorbance of a probe dye.
聚对苯二甲酸乙二醇酯（PET）纤维由于其良好的物理性能和耐化学性而被广泛应用于各个领域，但 PET 的疏水性严重限制了其在许多应用中的使用。通常需要进行湿化学处理来诱导亲水性，但这可能会损坏聚合物基质并产生大量的废液。与湿化学处理相比，常压辉光放电等离子体（APGDP）是一种替代方法，也是获得类似或更好的聚合物材料结果的环保方法。通过改变等离子体气体混合物、气体通量和电极温度，研究了卷对卷 APGDP 处理后 PET 样品的亲水行为。通过发射光谱法对等离子体腔中形成的反应性物质进行了表征。通过接触角测量、原子力显微镜和探针染料的紫外/可见吸收来表征诱导的表面功能化和粗糙度。
