Study on Aging of Zinc Oxide/Poly(butylene succinate) Composite

Zinc oxide/poly (butylene succinate) composite (ZnO/PBS) were performed by aging test of 1008h. The chemical structure and crystallinity of the materials were characterized by fourier transform infrared spectroscopy and X-ray diffraction, and the aging properties of composite were studied by mechanical properties. The results showed that: the scale of characteristic functional groups had some change. And any of the reciprocal actions or effects, that can occur in composite molecule. The crystallinity of composite had reduced from 26.13% to 15.56% after aging. Mechanical properties of materials reduced gradually in aging, and reduced extent of ZnO/PBS composite was less than that of PBS.
