Effects of Levan on the Biodegradability and Thermal Properties of Polybutylene Succinate

Abstract:

In this study, the biodegradability and the thermal properties of PBS and levan were prepared in the internal mixer with levan contents of 0, 0.5, and 1 wt%. The results from Differential Scanning Calorimetry (DSC) present that the melting temperature of PBS was slightly decreased with increasing levan contents. That means there was no significant effect of levan on melting behavior of the composites at the added content. From the TGA thermograms, it could be seen that there was no significant effect on the thermal stability when adding levan. The degradation temperature at 5% weight loss for all composites were in the rage of 377-379 oC. Furthermore, char yields for all contents were closed to zero. Moreover, the water absorption of PBS/Levan composites was increased with levan content. The biodegradation was observed after 4-day burial period; the holes from degradation were larger with levan contents.
