“…In the PLA/PBS blends, the T g of the PLA component was close to that of pure PLA, indicating that PLA and PBS were thermodynamically incompatible [36]. In addition, only a slight decrease in the T m of PLA in the blends was observed (0.9-3.9°C), and so the presence of PBS did not significantly influence the T m .…”

This study aimed to improve the brittleness and thermal stability of poly(lactic acid) (PLA) by inclusion of poly(butylene succinate) (PBS) and microcrystalline cellulose (MCC). Of the three PLA/PBS blends (10, 30 and 50 wt% PBS) evaluated, the 70/30 wt% blend exhibited the highest impact strength and elongation at break, but a lower thermal stability compared to that of the pure PLA. Scanning electron microscopy analysis confirmed the better compatibility of this 70/30 PLA/PBS blend. This blend was further filled with MCC. Based on thermogravimetric analysis, the thermal stability of the 70/30 PLA/PBS blend was improved by the addition of MCC [optimal at five parts by weight per hundred (phr)] and further still by the addition of the chain extender, Joncryl TM , at 0.5 phr. The 70/30/5/0.5 PLA/PBS/MCC/Joncryl TM composite exhibited the highest impact strength, while the elongation at break was acceptable.

“…Extrusion can chemically modify polymers to improve thermal stability, mechanical strength, elongation, adhesive strength and other mechanical properties of polymers. This process involves grafting, in which monomers are covalently bonded onto the polymer chain [18][19][20][21][22] . Considerable work has been carried out in recent years using the different grafting techniques such as chemical, radiation and reactive extrusion.…”

Polyhydroxybutyrate fiber biocomposites were prepared via twin screw extrusion. Results show mechanical properties of short natural fiber composites can be greatly improved with the addition of a compatibilizer. Compatibilizer composites exhibited an increased resistance to water absorption at low temperatures. A considerable increase in flexural modulus was also observed, in particular for the jute fiber composites. The dispersion of fibers was visibly improved as was observed using optical microscopy which allowed for a more even transfer of stress throughout the composite matrix. Lyocell composites however continued to display fiber agglomerates and although these were visibly reduced as PHB-g-MA content increased.

To improve the interfacial interaction between poly(lactic acid) (PLA) and bamboo particles (BP), sodium hydroxide solution was employed to pretreat BP, and then maleic anhydride (MAH) was used to compatibilize PLA/ BP biocomposites. The biocomposites were prepared through melt blending and hot-pressing. Effects of MAH concentration on the properties of BP and PLA/BP biocomposites were investigated using Fourier transform infrared spectroscopy, mechanical measurements, differential scanning calorimetric, melt flow rate (MFR) analysis and scanning electron microscope. Results showed that interfacial interaction between PLA and BP in the biocomposites was improved with MAH compatibilizer. Tensile strength and elongation at break of PLA/BP biocomposites, reached maximal values of 47.6 MPa and 6.22 %, respectively, when treated with 1.0 % MAH. Maximal flexural strength of 72.61 MPa and flexural modulus of 4.65 GPa were obtained with 0.5 % MAH treatment, and thermal properties were also improved at this concentration. MFR of the blends was enhanced with MAH compatibilization.
