| 摘 要： | 采用阳极氧化法对炭纤维进行连续表面改性,并在其表面进行电镀镍处理,利用扫描电子显微镜(SEM)、X射线衍射(XRD)、热重分析和酸碱滴定等方法研究了炭纤维阳极氧化前后的物理化学结构及对炭纤维电镀镍镀层的影响。结果表明:经过阳极氧化处理后,炭纤维表面的总酸性官能团提高约10倍;炭纤维拉伸强度降低先慢后快;阳极氧化可以改善镀层的生长过程,使镍镀层的生长由(V-W)模式转变为(F-M)模式,并且促使镀层晶粒细晶化,N i晶粒尺寸由14.5nm降为11.2nm,提高了镀镍炭纤维的抗氧化性以及镀层与炭纤维的结合力,阳极氧化后镀镍的炭纤维初始氧化温度较镀镍炭纤维提高了50℃。

| Abstract: | PAN-based carbon fibers were continuously treated by anodic oxidation followed by electrodeposition of Ni on their surface.The influence of anodic oxidation on mechanical properties,surface morphology,amount of surface acidic groups and growth mode of the Ni coating were studied by SEM,XRD,TG and conductometric titration.Results showed that the total amount of surface acidic groups on the oxidized carbon fibers is about 10times as large as that of the untreated ones and the tensile strength of carbon fibers... |
