Recently, the green polymers such as the biodegradable polymers are attracting substantially more attention. Due to the characteristics of biodegradation, good processability, and mechanical properties, many studies have been devoted to exploring the scientific and technological issues of biodegradable polymers. The crystallization property is important among the physical properties of polymeric materials because it is closely related to processing and end-use application. In this work, we discovered the novel blends and composites comprising biodegradable polymers and thoroughly discussed their crystallization properties. We found that in the blends of green ionic liquid and biodegradable poly(3-hydroxybutyrate) (PHB), ionic liquid influenced the crystallization behaviors of PHB. Discussions on mathematic modeling analysis indicated that the crystallization rate of PHB was decreased when the ionic liquid content was increased in the blends. The presence of ionic liquid would retard the crystallization kinetics of PHB. Possible ion-dipole interactions were suggested between the ionic liquid and PHB according to the spectroscopy results. Finally, multinary composites containing biodegradable poly(ethylene succinate) (PESu) were also discussed for the interest in their crystallization properties. The superior crystallization kinetics in the multinary PESu composites with the plasticizer and the nucleation agent were investigated. |
