Compression of Multilayered Composite Electrospun Scaffolds: A Novel Strategy to Rapidly Enhance Mechanical Properties and Three Dimensionality of Bone Scaffolds

Figure 1

SEM of electrospun PDO scaffolds after biomimetic mineralization in SBF for 2 weeks. (a)-(b) Compressed and noncompressed control scaffolds in deionized water. (c)-(d) 1-layer compressed and noncompressed scaffolds in SBF, (e)-(f) 2-layers C1M2 and C2M1, (g)-(h) 4-layers C1M2 and C2M1. PDO scaffolds containing 50% nHA are designated in the same format. (i)-(j) Compressed and noncompressed control scaffolds in deionized water. (k)-(l) 1 layer compressed and noncompressed scaffolds in SBF, (m)-(n) 2 layers C1M2 and C2M1, and (o)-(p) 4-layers C1M2 and C2M1. Scale bars = 20 𝜇m.
