Abstract

Molecular-structure variation of organic materials irradiated with atmospheric pressure He plasma jet have been investigated. Optical emission spectrum in the atmospheric-pressure He plasma jet has been measured. The spectrum shows considerable emissions of He lines, and the emission of O and N radicals attributed to air. Variation in molecular structure of Polyethylene terephthalate (PET) film surface irradiated with the atmospheric-pressure He plasma jet has been observed via X-ray photoelectron spectroscopy (XPS) and Fourier transform infrared spectroscopy (FT-IR). These results via XPS and FT-IR indicate that the PET surface irradiated with the atmospheric-pressure He plasma jet was oxidized by chemical and/or physical effect due to irradiation of active species.

摘要

已对用大气压氦等离子体射流辐照的有机材料的分子结构变化进行了研究。测量了大气压氦等离子体射流中的光发射光谱。该光谱显示出相当数量的氦线发射，以及归因于空气的氧和氮自由基的发射。通过X射线光电子能谱（XPS）和傅里叶变换红外光谱（FT-IR）观察了用大气压氦等离子体射流辐照的聚对苯二甲酸乙二酯（PET）薄膜表面的分子结构变化。这些通过XPS和FT-IR得到的结果表明，用大气压氦等离子体射流辐照的PET表面由于活性物种的辐照而通过化学和/或物理效应被氧化。
