“…Pure PBS is limited by its low impact strength . To overcome this problem researchers have focused on blending PBS with other aliphatic polyesters like poly(hydroxyl butyrate), poly(ethylene oxide), poly (butylene terephthalate), and poly(butylene carbonate) . These blends with the exception of poly(butylene carbonate) have a detrimental effect on the biodegradability of PBS.…”

This work studies the effect of processing parameters on mechanical properties and material distribution of co-injected polymer blends within a complex mold shape. A partially bio-sourced blend of poly(butylene terephthalate) and poly(trimethylene terephthalate) PTT/PBT was used for the core, with a tough biodegradable blend of poly (butylene succinate) and poly (butylene adipate-co-terephthalate) PBS/PBAT for the skin. A 1 =2 factorial design of experiments is used to identify significant processing parameters from skin and core melt temperatures, injection speed and pressure, and mold temperature. Interactions between the processing effects are considered, and the resulting statistical data produced accurate linear models indicating that the co-injection of the two blends can be controlled. Impact strength of the normally brittle PTT/PBT blend is shown to increase significantly with co-injection and variations in core to skin volume ratios to have a determining role in the overall impact strength. Scanning electron microscope images were taken of co-injected tensile samples with the PBS/PBAT skin dissolved displaying variations of mechanical interlocking occurring between the two blends.

“…In general, for homogeneous blend systems, the Han−Huang plot usually exhibits a composition-independent correlation, whereas the incompatible systems display a composition-dependent correlation. 39,40 In the LLDPE/ATPS blends, a concentrationdependent correlation was observed at the lower angular frequency for samples with higher ATPS content, such as L6 and L7M. L6M was found to have shown a better compatibility, of which the correlation was similar to those with less ATPS content blends.…”

Antimicrobial packaging films have been widely used in various applications. However, because of concerns regarding safe food and consumer demands for preservative-free products, the antimicrobial agents applied to packaging have to be highly effective and the leaching effect is not allowed. In the present work, the antimicrobial agent polyhexamethylene guanidine hydrochloride was compounded with starch to prepare antimicrobial thermoplastic starch (ATPS). ATPS was then melt-blended with linear low-density polyethylene (LLDPE) to prepare the novel antimicrobial packaging film. The resultant LLDPE/ATPS films exhibited excellent antimicrobial properties against Escherichia coli in the shaking-flask test. The ringdiffusion test further confirmed the nonleaching effect of the films. However, the addition of ATPS decreased the crystallinity of LLDPE. Both rheological analysis and scanning electron microscopy images indicated that a high ATPS content might result in poor compatibility even in the presence of a compatibilizer.

“…The peaks of PBS were observed at 2θ = 19.70, 22.55, and 28.89. [36] The major characteristic peaks of TTCP, at angles of 2θ = 29.32, 29.89, 31.20, 32.14, and 32.46, were evident when TTCP was added into the PBS.…”

Tetracalcium phosphate (TTCP, Ca 4 (PO 4 ) 2 O) was functionalized by poly (l-lactic acid) (PLLA) in order to improve the dispersion of TTCP particles in poly (butylene succinate) (PBS) matrices, and then a series of the PLLA grafted TTCP/PBS (g-TTCP/PBS) composites were prepared via melt processing. Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), tensile analysis, differential scanning calorimetry (DSC), thermogravimetric analysis (DTG/TGA) and melt rheological analysis were used to investigate the structure and properties of the g-TTCP/PBS composites. The results revealed that l-lactide could be grafted onto the surface of TTCP, and the g-TTCP/PBS composites showed the best mechanical properties when the content of g-TTCP was 10 wt%. The crystallization temperature of g-TTCP/PBS composites tended to increase with the increase of g-TTCP contents. The functionalized particles played an important role in augmenting the thermal degradation rate and the complex viscosity of the composites due to their unique structure and the reasonable interfacial interaction between the particles and PBS matrix.
