Abstract
The presented paper concerns scientific research on processing a poly(lactide-co-glycolide-co-trimethylene carbonate) copolymer (PLLAGLTMC) with thermally induced shape memory and a transition temperature around human body temperature. The material in the literature called terpolymer was used to produce smart, nonwoven fabric with the melt blowing technique. Bioresorbable and biocompatible terpolymers with shape memory have been investigated for its medical applications, such as cardiovascular stents. There are several research studies on shape memory in polymers, but this phenomenon has not been widely studied in textile products made from shape memory polymers (SMPs). The current research aims to explore the characteristics of the PLLAGLTMC nonwoven fabric in detail and the mechanism of its shape memory behavior. In this study, the nonwoven fabric was subjected to thermo-mechanical, morphological, and shape memory analysis. The thermo-mechanical and structural properties were investigated by means of differential scanning calorimetry, dynamic mechanical analysis, scanning electron microscopic examination, and mercury porosimetry measurements. Eventually, the gathered results confirmed that the nonwoven fabric possessed characteristics that classified it as a smart material with potential applications in medicine.

The material in the literature called terpolymer is defined as a polymer that consists of three distinct monomers ( known as ABC triblock copolymers). The poly(lactide-co-glycolide-co-trimethylene carbonate) copolymer (PLLAGLTMC) was obtained in a ring open polymerization (ROP) using zirconium (IV) acetylacetonate as a terpolymerization initiator. The used zirconium complex was shown to be effective and have low toxicity [12,14,15]. The low toxicity of Molecules 2017, 22, 1325; doi:10.3390/molecules22081325 www.mdpi.com/journal/molecules
