Biodegradable Poly

Biodegradable poly(butylene succinate) (PBS)/Alfa fiber biocomposites were prepared through the compression molding method. Scanning electron microscopy images were acquired to assess the effects of reinforcement and homogenization of mixtures and to determine the characteristics of the microstructure. The rheological properties, melting, and crystallization behavior of neat PBS and its biocomposites were investigated. Regarding the thermal properties, it was observed that the presence of Alfa fibers facilitates the crystallization of the PBS matrix, which suggests that Alfa cellulose fiber acts as a nucleating agent. The rheological analysis suggests that the biocomposites show a better dynamic behavior with the addition of Alfa fibers. Indeed, the incorporation of fibers increased the complex modulus and complex viscosity of the composites. Also, increasing the percentage of fibers in the matrix induces percolation, the shift and change in the slope of Cole–Cole curve of the PBS/Alfa fiber composite compared to that of neat PBS indicate that the PBS microstructure has changed with the addition of fibers. Moreover, the improvement of biocomposites properties is believed to be largely attributable to the homogeneous dispersion of the Alfa fibers within the polymer matrix and also to the strong interfacial interactions between the two constituents.

Plastic Industry

In the plastic industry, recycling waste from production is normal practice for reducing waste and cost. When they were reproduced, their mechanical properties are changed. These changes may affect the quality of the end product. Hence, this work studied the mechanical, thermal and rheological properties of recycled biodegradable poly (butylene succinate) (PBS) with reproduction of 10 cycles. The results showed that tensile strength was slightly increased with increasing reproduction cycle until 6thcycles and reduced in the further cycles, respectively. The elongation at break was abruptly decreased with an increase of the cycle number. Moreover, the hardness was quite constant in the lower cycle number but it was slightly decreased in the higher one. Melt flow index (MFI) measurements indicated a significant change in the material after 2rdrecycles. The results on thermal properties measurement showed that degree of crystallinity decreased in the 6thcycles.
