Material and mechanical characterization of xSIBS. (A) ATR-FTIR spectroscopy was performed on samples of xSIBS with 25% styrene content that were either unused or had been exposed to GFP and fluid shear stress of 20 dyne/cm2 for 12 min in the HSD. A divergence region at 1160 cm−1 indicates C-O bonds on the used xSIBS sample. (B) Tensile testing results for 6 xSIBS specimens indicate nonlinear hyperelastic behavior, with ultimate tensile strength at approximately 35 MPa.
