| Popis: | This article presents data from the investigation of the thermal characteristics and mechanical behaviors of twelve different compositions of a polyurethane shape memory polymer (SMP). Each of the SMP compositions has a unique molar ratio of three monomers: (i) hexamethylene diisocyanate (HDI), (ii) N,N,N′,N′-Tetrakis(2-Hydroxypropyl)ethylenediamine (HPED), and (iii) Triethanolamine (TEA). The thermal characteristic datasets for each composition include the glass transition temperatures, as obtained from differential scanning calorimetry (DSC) and dynamic mechanical analysis (DMA), and the thermal degradation thresholds, as found from thermogravimetric analysis (TGA). The mechanical behaviors of the SMPs are represented by the failure stresses and strains, as obtained by cyclic tensile testing and failure testing, respectively. The interpretation of these measurements as well as a discussion of the potential usage of candidate SMP compositions for medical devices can be found in the companion article by Kunkel et al. (2018) [1], “Synthesis and characterization of bio-compatible shape memory polymers with potential applications to endovascular embolization of intracranial aneurysms.” Value of the Data • The data presented in this DiB article will provide quantitative measurements of the thermal characteristics and mechanical properties of twelve different compositions of aliphatic polyurethane shape memory polymers (SMPs), associated with glass transition temperatures that may permit their usage in biological applications. • This information can assist researchers in making informed selections or comparisons of SMP compositions for research applications, such as SMP-based endovascular embolic aneurysm devices or other biomedical devices. • The glass transition temperatures and elastic modulus reduction values may be used for in the development of an SMP-based device with desired biologically compatible actuation temperature and mechanical properties for endovascular aneurysm occlusion. • This data may also be useful in informing researchers of adjustments to be made to the SMP molar compositions that will allow fine tuning for targeted SMP thermomechanical properties for specific applications, as performed by Landsman et al. (2016) in the development of an SMP-based peripheral occlusion device [2]. |
