  Abstract

In this study, a series of novel controllable shape-memory polymers composed of poly(ethylene terephthalate) (PET) and poly(琯-caprolactone) (PCL) were synthesized using the one-pot method and were spun using the melt spinning process. The chemical structure and composition, thermal properties, crystallization properties, mechanical properties, and shape-memory behavior of these copolymers were characterized. The results revealed that the incorporation of a flexible PCL segment achieved random copolymers. The aliphatic PCL segment decreased the melting point, crystallinity, and glass transition temperature. The thermal stability of the synthesized PET-co-PCLs was higher than that of the blended polymers, and the decomposition temperature of PET-co-PCL-30 % reached 377.2 . The shape recovery ratio of PET-co-PCL-30 % was between 38.32 % and 82.69 % and was temperature dependent. The as-spun PET and PET-co-PCL fibers were melt spun at a winding rate of 1,000 m/min. The strength values of the fibers ranged from 2.16 to 1.2 gf/den depending on the increase in PCL content. Because of the biocompatibility of both PET and PCL and the shape-memory features of these copolyesters, PET-co-PCL fibers can be applied in intelligent textiles.
