摘　　要：采用氨气等离子体接枝环氧涂层工艺对芳纶Ⅲ进行表面改性,采用红外光谱、扫描电镜、原子力显微镜等对改性前后纤维表面的化学组成、形貌、粗糙度、浸润性能进行了研究。结果表明:经氨气等离子体接枝环氧涂层处理后,环氧树脂涂层能够以化学键形式接枝到芳纶Ⅲ表面,同时纤维表面的粗糙度有了明显的增加,浸润性得到显著的改善。The method of NH3-plasma-grafted coating was employed to modify the surface of aramid fiber m. The changes of the surface chemical structure, the surface morphology, the surface roughness and the wettability of fibers were characterized by Fourier transform infrared spectroscopy, scanning electron micro- scope, atomic force microscopy, respectively. The results indicated that the epoxy coating had been success- fully grafted onto the fibers, the roughness and the wettability of fiber surface were both improved after NH3- plasma-grafted coating.
