| Popis: | The 3D-printing technology allows to manufacture polymers into desired shape. This work presents novel bio-based copolyesters (PHPF) prepared by the polycondensation of 2,5-furandicarboxylic acid, 1,6-hexanediol and 1,2-propanediol as 3D-printed materials. These PHPF exhibit superior thermal stability. By tailoring the contents of 1,2-PDO, the PHPF exhibit optimum mechanical properties with tensile strength of 42.7 Mpa, elongation at break of 515% and impact strength of 35.62 KJ/m2, respectively. The 3D-printed PHPF shows a satisfactory mechanical properties obtained from tensile test and reliable microstructure observed by SEM. Both the thermal stability and mechanical properties of PHPF were far beyond polylactide, a present most used bio-based 3D-printed polymer, which revealed PHPF deserve to be promising 3D-printing materials. |
