| 摘 要： | 碳纤维表面可接枝上高聚物活性官能团,以调节复合材料中纤维与树脂之间的界面效应,从而改善复合材料的性能,通过控制接枝高聚物的结构可以很好的设计具有预定性能的界面层。热处理对纤维的强度不会造成影响,其表面官能团含量在1h附近达到最大值。未经异氰酸酯接枝处理的碳纤维表面没有聚合接枝尼龙大分子,热处理后再经过异氰酸酯处理,能明显看到尼龙分子接枝到纤维表面。当聚合单体中不添加活化剂,纤维表面的树脂接枝率可达到18.8%;单体中添加0.003的活化剂(占单体摩尔比),碳纤维表面的尼龙6接枝率只有7.65%,这是单体基体与纤维界面反应竞争的结果。碳纤维表面对原位聚合生成的尼龙以及改性尼龙结晶有很大影响,碳纤维未接枝处理时表面形成的横晶比较少;碳纤维接枝处理后可以看见纤维附近存在大量晶体结构,结晶体密度高,有利于材料性能改良。
