Table 4.
Changes in physical dimensions on stretching in the warp direction for samples PCL A and PCL B. The scaffolds showed an increase in volume when the samples were stretched, demonstrating a negative Poisson’s ratio.
| Scaffold Samples | Before Extension in Warp Direction | After Extension in Warp Direction | Change in Volume | ||||||
|---|---|---|---|---|---|---|---|---|---|
| Length (mm) | Width (mm) | Thickness (mm) | Volume (mm3) | Length (mm) | Width (mm) | Thickness (mm) | Volume (mm3) | ||
| PCL A | 50 | 50 | 0.87 | 2175 | 88 | 50 | 0.8 | 3520 | +61.8% |
| PCL B | 40 | 50 | 1.84 | 3680 | 105 | 50 | 0.76 | 3990 | +8.4% |
