以二氧化钛(TiO2)为填料,聚偏氟乙烯(PVDF)、聚甲基丙烯酸甲酯(PMMA)为基体,通过熔融共混制备PVDF/PMMA/TiO2复合薄膜,采用扫描电子显微镜、紫外/可见分光光度计、差示扫描量热仪和力学性能测试等方法表征了其各种性能。研究表明,PVDF与PMMA有良好的相容性,TiO2可以均匀的分散在基体中;TiO2的加入对材料的力学性能产生一定的影响,同时通过剥离实验对PVDF/PMMA/TiO2复合薄膜的粘结性能进行了表征。
PVDF / PMMA / TiO2 composite films were prepared by melt blending with titanium dioxide (TiO2) as filler, polyvinylidene fluoride (PVDF) and polymethylmethacrylate (PMMA) as the matrix and scanning electron microscopy and UV / visible spectroscopy Photometer, differential scanning calorimeter and mechanical properties testing methods to characterize its various properties. The results show that PVDF has good compatibility with PMMA and TiO2 can be uniformly dispersed in the matrix. The addition of TiO2 has certain influence on the mechanical properties of PVDF / PMMA / TiO2 composite films Performance was characterized.
