摘　　要：为研究乙烯-乙烯醇共聚物(EVOH)基体对复合材料性能的影响,分别制备了EVOH-56(乙烯醇基含量为56%)/纳米TiO2复合材料、纳米ZnO复合材料、纳米蒙脱土复合材料,EVOH-68(乙烯醇基含量为68%)/纳米TiO2复合材料、纳米ZnO复合材料、纳米蒙脱土复合材料。根据TPT方程,分别计算出体系中各组分间相互作用相关的参数B,分析了基体对体系力学性能的影响。结果表明,EVOH-68/纳米TiO2,ZnO体系的参数B值小于EVOH-56/纳米TiO2,ZnO体系,并且相关力学性能数据也证明EVOH-68/纳米TiO2,ZnO体系的相间相互作用好,力学性能优于EVOH-56/纳米TiO2,ZnO体系。EVOH-56/纳米MMT体系和EVOH-68/纳米MMT体系的力学数据与TiO2,ZnO体系一起证明了复合体系的力学性能是两种机理竞争的结果。In order to study the effect of EVOH matrix on the properties of composites,various composites,comprising EVOH-56 （56 mol % vinyl alcohol）/nano TiO2,ZnO,EVOH-56/nano montmorillonite,EVOH-68 （68 mol % vinyl alcohol）/nano TiO2,ZnO,EVOH-68/ nano montmorillonite were prepared by melt blending. Correlation parameter B,which characterizes the mutual action of components,was calculated according to equation of TPT. Also the effect of matrix on mechanical properties of composites was analysed. It is found that the values of B of EVOH-68/TiO2,ZnO are less than these of EVOH-56/TiO2,ZnO,indicating that the former systems exhibit better mutual action compared to the latter ones. The higher mechanical properties of EVOH-68/TiO2,ZnO confirms the action as well. Mechanical test of EVOH-56/nano montmorillonite,EVOH-68/nano montmorillonite and systems with TiO2,ZnO proved that the properties of composites are determined by the competition of two mechanism.
