Study on Structure and Properties of Degradable Polymer/Modified Nano-Si0₂ Composites

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.
