The Acylation of Carbon Fiber Surface and Its Graft Polymerization with Polyamide 6 Ⅰ.The Grafting Methods and Mechanical Property of CF/PA6 Composites

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0.030提高到接枝PA6后的0.061. 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%.
