摘要
用氧气等离子体处理芳III纤维的表面,考察了等离子体处理前后芳III纤维表面性能的变化。使用红外光谱分析(FT-IR)、X射线光电子能谱(XPS)、扫描电子显微镜(SEM)、原子力显微镜(AFM)和动态接触角等手段研究了等离子体处理前后芳III纤维化学结构、表面元素组成、表面形貌、表面粗糙度和表面浸润性能的变化。结果表明,在保持纤维本体结构不变的前提下用氧等离子体处理在纤维的表面引入了含量分别为20.1%和8.1%的新极性官能团(C-O和COO)。经氧等离子体处理后纤维表面的沟槽和起伏增多,粗糙度增大。用等离子体处理使纤维表面的浸润性能明显提高,总表面自由能由49.9 m J/m^2提高到67.1 m J/m^2。
Oxygen plasma treatment was used to modify the surface of aramid fiber III. The changes of fiber surface before and after oxygen plasma treatment was investigated in this paper. The surface chemical structure, element composition, surface morphology, surface roughness and surface wettability before and after oxygen plasma treatment were analyzed by FTIR, X-ray photoelectron spectroscopy（XPS）, scanning electronic microscopy（SEM）, atomic force microscopy（AFM） and dynamic contact angle analysis（DCAA）, respectively. It was found that oxygen plasma treatment introduced some newly polar groups such as（C-O and O-C=O） to fiber surface, the content of which were 20.1% and 8.1%, respectively. After oxygen plasma treatment, the roughness of fiber surface increased and surface grooves and ups and downs were increased obviously. It was also shown that the fiber surface wettability was improved significantly by oxygen plasma treatment. The total surface free energy increased from49.9 m J/m^2 to 67.1 m J/m^2.
