- Abstract
- Renewable poly(ether-block-amide)s (PEBAs), with different polyamide/polyether (PA/PE) ratios, are characterized for the development of biomedical devices. The effect of the chemical composition on the mechanical properties is studied via Fourier transform infrared (FTIR) spectroscopy, thermogravimetric analysis (TGA), differential scanning calorimetry (DSC), tensile tests, dynamic mechanical analysis (DMA), and broadband electric spectroscopy (BES). FTIR spectroscopy evidences the presence of different PA crystalline domains depending on the PA/PE ratio, as also evidenced by TGA and DSC. Such differences influence the molecular dynamics, as shown by DMA and BES, and the mechanical properties characterized by tensile tests. Indeed, PEBAs with a higher PA/PE ratio are stiffer due to a higher crystalline degree. (literal)
