- Abstract
In this paper, poly(butylene succinate) (PBS)/hollow glass microsphere (HGM) composites were prepared with three HGM - K25, S60 and S15. The true density of K25, S60 and S15 were 0.248, 0.604, 0.153 g cm-3, while their average particle size (D50) were 55, 30, 55 mm, respectively. PBS/HGM composites were prepared by a twin screw extruder and an injection molding machine. The melting and crystallization behaviors, mechanical properties, as well as morphology were investigated. Thermal and crystallization behavior test results indicated that the degree of crystallinity of PBS increased by at least 1.7 times with the addition of HGM at all types. Microscopic observation indicated some agglomerations and the pulled-out HGM particles. These restricted the HGM-polymer matrix stress transfer and reduced the tensile strength of the composites. Moreover, some broken HGM particles were clearly observed at 7.5 and 10 wt. %, especially for the HGM with K25 and S15. The density of the PBS/HGM composites were all reduced with the concentration. Minimum density reduction by 17 % was observed when S60 was applied at 10 wt. %.
