(A, B) SEM and 3D optical profile of 3D woven PCL scaffold surface. Outlined area in panel A denotes total scanned area in panel B. (C) Cross-sectional image of 3D woven PCL scaffold. (D, E) SEM and 3D optical profile of 3D woven PCL-Alg/PAAm IPN composite surface. Outlined area in panel D denotes total scanned area in panel E. (F) Cross-sectional image of 3D woven PCL-Alg/PAAm IPN composite scaffold. (G, H) SEM and 3D optical profile of Alg/PAAm IPN surface. (I) Average RMS of the 3D woven PCL scaffold (scaffold), Alg/PAAm IPN (hydrogel), and 3D woven PCL-Alg/PAAm IPN composite (composite) constructs. * P < 0.05 for hydrogel vs. scaffold & composite. + P < 0.05 for composite vs. scaffold and hydrogel. All scale bars = 200 µm.
