| 摘 要： | 为研究纳米填充物对EVOH基体性能的影响,采取熔融共混的方法,用EVOH-56作为基体,按照不同比例填充了化学结构或聚集态结构不同的纳米粉体,从而制备出不同的EVOH纳米复合体系。根据TPT方程,计算出与复合体系中各组分间相互作用相关的参数B值,EVOH-56/纳米TiO_2复合材料的B值(16.493)大于EVOH-56/纳米ZnO复合材料的B值(3.806);随着纳米粉体含量的增加,两种复合物体系的熔体温度升高约6%;而在相同纳米粉含量条件下,EVOH-56/纳米ZnO体系的加工扭矩比EVOH 56/纳米TiO_2体系低5%～10%;在力学性能方面,EVOH-56/nano-ZnO体系的屈服强度值和弹性模量值均优于EVOH 56/nano-TiO_2体系。

| Abstract: | To study the influence of filled nano-particles on the EVOH substrate performance,EVOH nano-composites with EVOH-56 as substrate filled with nano-particles of different chemical structures and aggregation states were prepared by melt blending.The interaction parameter B among different components of composites was calculated according to the TPT equation.The results indicate that B value of EVOH-56/nano-TiO_2(16.493)is greater than that of EVOH-56/nano-ZnO(3.806),and the melting temperatures of both composi... |
