研究了大气压等离子体对聚对苯二甲酸乙二醇酯（PET）分子结构的影响。用发射光谱法分析了等离子体成分。除了强He谱线外，还检测到O和N自由基谱线。利用傅里叶变换红外光谱和x射线光电子能谱研究了PET膜表面分子结构的变化。研究发现，等离子体辐照由于活性物质的化学和物理作用导致表面氧化和降解。结果证明了在局部尺度上观察等离子体与有机物质相互作用的可行性。
The effect of atmospheric pressure He plasma on the molecular structure of polyethylene terephthalate (PET) has been investigated. The plasma composition was analyzed using optical emission spectroscopy. In addition to strong He emission lines, lines due to O and N radicals were also detected. The change in the molecular structure of the PET film surface was investigated using Fourier transform infrared spectroscopy and X-ray photoelectron spectroscopy. It was found that plasma irradiation led to oxidation and degradation of the surface due to chemical and physical effects of the active species. The results demonstrate the feasibility of observing the interaction of plasma with organic material on a local scale.
