摘　　要：通过碳纤维 (CF)表面官能团的酰氯化 ,采用阴离子接枝反应制备了表面接枝尼龙 6 (PA6 )的碳纤维。SEM观察表明 ,接枝PA6的CF表面呈粗颗粒状形态。XPS结果表明 ,CF表面N/C比例由接枝前的0 0 30提高到接枝PA6后的 0 0 6 1。接枝率达 2 .1%以上。接枝PA6的CF增强了CF与PA6复合材料界面的相互作用 ,剪切强度提高了 14 %Chemical groups (—COOH, —OH) on carbon fiber surface were transformed into CF—COCl, which was used as an effective activating group for graft polymerization of MC nylon 6 onto carbon fiber (surface). The morphology of the graft nylon 6 on carbon fiber surface was characterized by SEM. The XPS (results) showed that the grafted carbon fiber has a higher N/C ratio from 0.030 to 0.061 on its surface. The grafting degree was above 2.1%. Grafting of nylon 6 improved the interface interaction between carbon fiber and nylon 6 matrix and increased the ILSS of CF/PA6 composites by 14%.
