Mechanical property of transformed 3D nanofiber scaffolds. (a) Compressive tests of cuboid-shaped nanofiber scaffolds (dimension: 20 mm × 10 mm × 10 mm) under 70%, 80%, and 90% compressive strains. (b) Compressive tests of 0.5% gelatin-coated, cuboid-shaped nanofiber scaffolds under 70%, 80%, and 90% compressive strains (the 70% compression curve is behind the 80% compression curve). (c) Cyclic compressive tests of cuboid-shaped nanofiber scaffolds under 90% compressive strain (1, 10, and 20 cycles). (d) Cyclic compressive tests of 0.5% gelatin-coated, cuboid-shaped nanofiber scaffolds under 90% compressive strain (1, 10, and, 20 cycles). (e) Elastic modulus of cuboid-shaped nanofiber scaffolds with and without 0.5% gelatin coating under different compressive strains. (f) Energy loss coefficients of cuboid-shaped nanofiber scaffolds with and without 0.5% gelatin coating under different compressive strains. **p < 0.01.
