利用纤维素纳米晶须(CNW)的水可分散性,分别将CNW水悬浮液均匀分散在水性环氧树脂基多元醇和水性萜烯基环氧树脂分散体中.以旋转流变法分析了CNW对水性树脂体系流变行为的影响,结果表明:复合体系的黏度都随CNW添加量的增加而增大.用粒径分析仪观察了CNW对复合体系的粒径及其分布的影响,加入CNW后分布曲线出现了CNW粒径峰,粒径峰面积的变化与CNW的加入量成正比.复合体系的原子力显微镜分析表明:CNW能均匀无序地分布在水性树脂体系中.复合产物的拉伸测试表明,复合涂膜的拉伸模量和拉伸强度都随着CNW添加量的增加而显著提高,断裂伸长率随CNW添加量的增加而下降.接触角测定表明,添加CNW可以提高复合涂膜表面的疏水性.
