summarizes some mechanical and physical properties
of the composite films with and without ZnO. Overall, the film
impact strength of PBS slightly decreased with increasing ZnO content from 19.2 to 13.6 J/cm when ZnO was applied at 6 wt%.
This implied no complete stress transfer paths were occurred
under impact force. In comparison, the film impact strength was
larger than that of commercial poly(lactic acid) (PLA) by more than
fivefold
