Abstract
By using Isopropyl tri (dioctylpyrophosphate) titanate modified nanoSi02. Poly (ε-caprolactone)(PCL) and Poly (Butylene Succinate Adipate)(PBSA) blends was prepared by melt mixing. Its structure and mechanical properties were studied respectively with infrared spectrometer (FT-IR), universal material testing machine and scanning electron microscope (SEM),and analysis the degradation behavior by soil buried experiment The results showed that the modified nanoSi02 content is 4%, the mechanical properties of composite degradation material is improved obviously. The SEM results showed that a low amount of modified nanoSi02 can be dispersed evenly in the blends, while agglomeration of was observed in blends with increasing modified nanoSi02 content. Compared with SEM image after degradation, the degradation behavior of the composites was good.
