Resistances of Nano-Titanium Dioxide on the Ultraviolet Aging of Poly(butylene succinate)

Abstract:

Poly (butylene succinate)/titanium dioxide nanocomposite was prepared by melt blending in a HAAKE mixer. The degradation was studied under ultraviolet aging conditions. The SEM results showed that there were not any visible pores in the nanocomposite surface, which indicated that the addition of TiO₂ could resist the ultraviolet degradation in some degree. The FT-IR results presented that the neat PBS and 1 wt% PBS/TiO₂ nanocomposite had an overall increased peak intensities, especially for the carbonyl group. The intensities of neat PBS after 72h ultraviolet aging were increased significant than that of the 1 wt% PBS/TiO₂ nanocomposite. FT-IR results further confirmed the SEM results and revealed the mechanism of the PBS degradation under ultraviolet aging conditions.
