Abstract:

Poly(ethylene 2,5-furandicarboxylate)(PEF)/poly(butylene succinate)(PBS) blends were obtained via melt blending, and the factors, such as the blending temperature, blending time, the screw speed and blending ratio on mechanical properties of PEF/PBS blends were studied in details. Their compatibility, thermal property, and mechanical property were investigated by scanning electron microscopy, differential scanning calorimetry, thermogravimetric analysis, and tensile testing and impact testing. When the content of PBS is 15%, the optimal blending processing conditions are mixing the blends at 230 ℃ for 90 s under the screw rotation speed of 150 r/min. Under the optimal conditions, the compatibility and thermal performance are good, the impact strength and tensile strength are the largest. Compared to PEF, the impact strength and the tensile strength of the blend increase 6 times and approximate 20%, respectively. The results in this work provide a new possibility for the application of biobased polymers.
