氮等离子体处理对腈纶纤维表面性能的影响

Effects of nitrogen plasma treatment on surface properties of acrylic fiber

以氮气辉光放电等离子体技术处理腈纶纤维 ,利用SEM、BET和XPS等测试方法 ,分析等离子体处理前后纤维表面形态、元素组成及官能团的变化。结果表明 ,腈纶纤维经等离子体处理后表面粗糙度增加 ,大量的含氧和含氮极性基团被引入到纤维表面 ,使纤维表面吸湿性能得到显著改善。

Acrylic fiber is treated with nitrogen glow discharge plasma; the treated surface is characterized by scanning electron microscopy (SEM), specific surface area analysis (BET) and X ray photoelectron spectroscopy (XPS). It is found that plasma treatment can impart the acrylic fiber increased surface roughness and the improved hygroscopicity by the introduction of polar functions containing oxygen and nitrogen.
