Abstract:
In this work, PLA /PEBA blends with the addition of different PEBA contents were prepared via self-made Triple-Single Screw Extruder, the phase morphology, mechanical properties thermal stability of PLA /PEBA blends with PEBA content were investigated. For the pure PLA, the tensile strength decreased, while the elongation at break and the impact strength increased significantly with addition of 15% PEBA. The which were improved nearly 23 and 5 times. The results illustrate that the soft component PEBA was beneficial to improve the tensile ductility and the toughness of PLA. SEM measurements indicate the PEBA and PLA intertwined with each other, two phases interface bond tightly, improving the compatibility of the blends when PEBA content is not more than 15 wt%, with further increasing PEBA, the two-phase interface appears and decreases the interfacial adhesion, resulting in the poor mechanical properties of blends.TG results reveal that thermal stability of PLA/PEBA blends was improved.
