摘要
为了改善芳纶的表面性能,利用介质阻挡放电,对其表面进行改性.在Ar,Ar/O2,Ar/N2不同气氛介质阻挡等离子体的处理后,探究芳纶表面所产生的不同作用效果机理,同时考察了O2和N2的流量对芳纶表面作用效果的影响.采用了微脱胶法、X射线光电子能谱(XPS)以及原子力显微镜(AFM)分别对处理后芳纶表面黏结性能、表面元素和官能团的变化以及表面粗糙程度的变化进行了比较.结果表明:对芳纶表面的改性是由刻蚀作用还是活性基团占主导与放电气体的种类密切相关,而通入气体的流量也会影响表面改性的处理效果.
Dielectric barrier discharge technique is used for surface treatment of aramid fiber in order to optimize its surface properties. The effects of different plasmas including Ar, Ar/O2 and Ar/N2 as well as their flux on the surface modification of aramid fiber are studied. Micro-bond test, X-ray photoelectron spectroscopy (XPS) and atomic force microscope (AFM) are utilized to characterize and compare the variations of surface adhesion, chemical composition, functional groups and surface roughness of treated aramid fibers, respectively. The results indicate that the type of plasmas and their flow rate would both influence the effects of surface modification, which determines whether the surface etching or the activating of functional groups plays dominant role in the surface modification of aramid fibers.
