Mechanical testing. (a) Tensile testing plot of samples strained parallel (||) or perpendicular ( ⊥ ) to fiber axis. (b) Comparison of fibrous PGS to previously reported mechanical properties for porous and non-porous films under similar conditions. Note: UTS values for nonporous and porous films was during testing of dry samples. C2 crosslinking was 120°C for all samples. C5 crosslinking for porous and nonporous films was 150°C-48h but 120°C-24h, 150°C-24h for fibers. (c) Multi-cycle testing of C5 sample, strained 10-100% for 100 cycles. (d) Suture retention strength.
