Figure 4: Comparison of (a) thickness, (b) stiffness (Young’s modulus), (c) strain at break, and (d) energy to break in multilayered mineralized electrospun PDO and PDO:nHA scaffolds under dry and hydrated testing conditions. The effects of compression welding the scaffolds are also shown. In scaffolds containing more than 1-layer, compression welding of the scaffolds was done before SBF treatment (C1M2) or the scaffolds were mineralized separately and then compressed at the end of 2 weeks (C2M1). Non-compressed (NC), compressed (Comp).
