“…Exfoliation of graphene in PBS has been achieved by Wang et al 9 when preparing PBS/graphene nanocomposite by solution processing. While in the case of PBS/GO composites, solution processing did not achieve exfoliation of GO as reported by Du et al 43,44 , and the exfoliation of GO was only achieved by in-situ polymerization as reported by Wang and coworkers 10 . While in-situ polymerization seems too complex to practical application, because this method usually requires suitable modification of conventional equipment and polymerization process.…”

“…Graphene and graphene oxide (GO) show many supreme properties such as high mechanical strength, Young's modulus, thermal conductivity, gas barrier property, and etc., which makes them ideal reinforcing fillers for various polymer matrices [38][39][40] . Both graphene and GO have been incorporated into PBS to reinforce mechanical properties 9,10,[41][42][43][44] . In-situ polymerization and solution processing are the two commonly used methods to incorporate graphene or graphene oxide into PBS.…”

“…The loading of exfoliated GO could decrease to show similar crystallization and mechanical behaviors in comparison with platelet-like dispersion. Although the morphology and non-isothermal crystallization kinetics of aggregated GO platelets reinforced PBS composites have been reported systematically 43,44 , those of exfoliated GO lamellas reinforced PBS nanocomposites have not been reported. Different crystallization and mechanical behaviors are anticipated if dispersion of GO enhanced.…”

Graphene oxide (GO) was incorporated into poly(butylene succinate) (PBS) via a solution coagulation method to fabricate PBS/GO nanocomposites. Scanning electron microscope and transmission electron microscope observations indicated that GO with very thin layer dispersed in PBS uniformly and showed a good interfacial adhesion with PBS matrix. Differential scanning calorimetry analysis suggested that the crystallization ability of PBS increased first and then decreased with increase in the content of PBS. Isothermal crystallization kinetics investigation manifested that the overall crystallization rate of PBS increased first and then decreased with increasing PBS content while the crystallization mechanism remained unchanged. Polarized optical microscopy analysis indicated that GO worked as an effective nucleating agent for PBS. X-ray diffraction characterization suggested that incorporation of GO did not change the crystal structure of PBS. Both tensile testing and dynamic mechanical analysis witnessed the reinforcement in mechanical performance of PBS by incorporation of GO.

The effect of epoxidized soybean oil on mechanical and rheological properties of poly(butylene succinate)/lignin via vane extruder AIP Conference Proceedings 1713, 120001 (2016) Abstract. The Butyl Glycidyl Ether (bge) is selected as a branch mononers and correspondingly poly(butylene succinate) PBS-bge copolymers is synthesised by polymerization. In this study, the dynamic viscoelastic is employed to study the rheological properties of homogeneous PBS and PBS-bge copolymers. The results indicated that all copolymers showed high mole weight and well matched the reaction mole ratio. But the PBS-bge copolymers exhibited a higher shear thinning behaviors than homogeneous PBS. And all PBS-bge copolymers exhibited a higher complex viscosity at low frequency indicating network-like structures were formed at the low shear frequency. In addition, the tanδ is remarkable decreased with the introducing of bge, which reflects that the elasticity of polymer is significantly improved. As a result, the branched modification has improved the ductility and toughness of the material obviously, especially when the branched ratio is more than 5%.
